To bring more variety in the hypoallergenic breeds, the expert breeders own crossed hypoallergenic dogs with other dog breeds. Most favorite breeds of them are Poodle, Chihuahua, Maltese, and Shih Tzu. Interestingly, Poodle is the one with over 2 dozens of crossbreeds including Goldendoodle, Shih Poo, Bernedoodle, and numerous others.
Researchers own shown that frequently bathing dogs reduces the quantity of allergen related protein on the fur or hair of the dog and the quantity of airborne allergen. Bathing a dog at least twice a week will minimize or even eliminate the reaction of an allergic person to a dog.
Frequent cleaning and vacuuming of the home, using air filters, restricting the dog to certain rooms, and adopting a little dog that can easily be given frequent baths are every recommended by the Humane Society of the United States to control allergens. Scientific research has repeatedly shown that excellent cleaning practices in the home remove allergens from the environment.
Many allergists propose that a dog not be introduced to the environment of a dog allergic individual.
While «allergy shots» can reduce numerous individuals’ dog-allergic reactions, the most common approach remains avoidance.
There own been recent studies suggesting early introduction of pets to home may reduce the likelihood of developing sensitization. There are reports of individuals who will become less sensitive with continued exposure to a pet in the environment. But allergists warn that pet owners cannot rely on a breed being non-allergenic just because a specific allergic pet owner can tolerate a specific dog of that breed.
Though some studies propose the possible existence of hypoallergenic dog breeds, there is too much variability to conclude that such a breed exists. According to researchers, claims about the existence of hypoallergenic dog breeds may own been fueled by unsubstantiated articles on the internet. In a recent interview, Christine Cole Johnson, Senior Staff Scientist at the Henry Ford Hospital & Health System, referring to the findings of her article in the July issue of the American Journal of Rhinology and Allergy, explained that it was unclear where the name hypoallergenic dog breed came from, and asserted that the existence of such a breed was just a myth. The significant allergens are proteins found in the dog’s saliva and dander. Some studies own suggested that the production of the allergen, and therefore human allergenic reaction, varies by breed, yet more recent scientific findings indicate that there are no significant differences between breeds in the generation of these allergens. One study found hypoallergenic breeds to own significantly more allergen in their coats than non-hypoallergenic breeds although there was no differences in the allergen levels in the air or on the floor.
Effect of size
Size may be a factor in determining hypoallergenicity.
It is possible that the entire body surface area of the dog is more indicative of reduced production of allergens than its breed.
Smaller dogs will also leave fewer environmental pollutants containing dog dander and dog allergens (reduced fecal matter, urine and saliva). Little hairless dogs may be less likely to cause allergic reactions «because it’s so simple to bathe them and the dander falls off them.» Dogs may leave behind urine, saliva and fecal matter as allergen sources. Dogs with access to the outdoors may introduce outdoor allergens such as mold and pollen with larger animals tracking in more of these allergens. It is well established that most individuals with dog allergy also suffer with additional environmental allergies. Individuals with dog allergy may also be at increased risk for human protein hypersensitivity with cross-reactivity of dog dander allergen and human seminal fluid.[clarification needed]
Breeds that shed less are more likely to be hypoallergenic, since the dog’s dander and saliva stick to the hair and are not released into the environment. However, protein expression levels frolic a major role and quantity of shedding alone does not determine degree of allergic reaction.
«Even if you get a hairless dog, it’s still going to produce the allergen,» Dr. Wanda Phipatanakul, chair of the Indoor Allergen Committee for the American Academy of Allergy, Asthma, and Immunology is quoted in the newsmagazine U.S. News & World Report as saying. How hypoallergenic a specific dog is for a specific person may vary with the individual dog and the individual person.
If a person is allergic, they may be best capable to tolerate a specific dog, possibly of one of the hypoallergenic breeds. Dr.
Thomas A. Platts-Mills, head of the Asthma and Allergic Disease Middle at the University of Virginia, explained that there are cases in which a specific dog (not breed) might be better tolerated by a specific person, for unknown reasons. «We ponder there really are differences in protein production between dogs that may assist one patient and not another,» Dr. Platts-Mills said.
All dogs shed, and every dogs produce dander and saliva in some degree. As noted above, the quantity of the allergenic protein present on the dander and in saliva varies by breed.
Also, the quantity of the allergen can be reduced or eliminated in individual dogs by treatments such as bathing. But for most breeds, when not regularly bathed, even a dog who sheds extremely little or has little dander can trigger a reaction in a sensitive person.
Barack Obama has promised the future First Daughters a dog, and his eldest, year-old Malia, has zeroed in on a so-called hypoallergenic breed to accommodate her allergies.
Her top pick is a goldendoodle, a cross between a golden retriever and a poodle, though the future prez has hinted about adopting a save dog, noting that "a lot of shelter dogs are mutts love me."
We asked Bernadine Cruz, a spokeswoman for the American Veterinary Medical Association, to explain the hypoallergenic concept. Cruz is a veterinarian in Laguna Hills, Calif., and in was also a paid spokeswoman for Allerca, a company that claimed to own bred a hypoallergenic cat.
For an update on Allerca and its research, see this tale in The Scientist.
This is an edited transcript.
Why are some people allergic to dogs?
For numerous people, being allergic to dogs is a matter of having a sensitivity to a protein in their saliva which also exudes through their skin.
Would a hypoallergenic dog be a excellent option for people who are otherwise allergic to pooches?
There is no such thing as a hypoallergenic cat or dog.
One cat has been bred that’s considered hypoallergenic: A company called Allerca in San Diego found a line of cats considered hypoallergenic because of a naturally occurring divergence (mutation) of the protein Fel d 1. The protein is (normally) found in cat saliva, urine and exudes from their skin. I’ve found people who are extremely allergic to cats who are capable to frolic with them and not own the sneezing. But in dogs, a mutation in any similar protein has not been found.
What types of dogs might be better for allergy suffers?
Every person will own his or her own degree of reactivity to certain dogs — their saliva and proteins in their bodies.
Those dogs that are more universally less allergenic come from more specific breeds such as Poodles, Kerry Blue Terriers, Schnauzers, Bichons and Lhasa Apsos. [They] don’t shed a lot or they go to the groomer frequently and by getting their hair washed and trimmed, get the allergens off their skin. When those dogs mate purposely or accidentally with breeds exterior of those breeds, their offspring may be less allergenic.
But some people can own allergies to a Poodle and then be playing with a German Shepherd and own no problem.
What about the Peruvian Hairless Dog, which that country has offered to the Obamas?
Is it better for allergy sufferers?
They’re not going to be shedding a lot, but (allergenic) proteins will exude through their skin so that’s not always going to be the answer.
Are purebred dogs healthier than other dogs?
There’s no difference.
Are purebreds available at shelters, or only through breeders?
Many times you will discover them in shelters. Going to shelters or breed rescues is a grand way for the Obamas or anyone to get a pet.
Q—I own a 6-year-old short-haired cat.
My husband had allergies when he was young. He always wanted a cat; so when we got married he said he would put up with any discomfort. Fortunately, it only bothered him for a while. Our doctor said my husband may own become immune to our cat.
We are expecting a kid shortly and are concerned that the kid might own the same allergies.
Also, my husband`s parents are moving and are not capable to take their 5-year-old poodle. We are fond of the dog and would love to own it.
I own been told that poodles are not likely to cause allergic reactions because of their hair. Is this is true?
A—To minimize exposure of your husband and kid to animal allergens, set aside one area, perhaps part of the basement, for grooming your cat and dog.
Don`t permit the kid access to that area. Groom both animals every two or three days.
These precautions may not be sufficient if the kid is allergic. A pediatrician or a pediatric allergist may be capable to tell you what the baby`s chances are of being allergic.
Poodles are less likely to cause allergies than some other breeds because they don`t own an undercoat that sheds extremely much. But they are not non-allergenic. The allergic reaction in people is a reaction to the saliva that dogs and cats lick onto their fur, to the microscopic flaking of surface skin, and to hair protein.
Someone extremely allergic to dogs probably will own a reaction to a poodle.
Q—How can I assist my 5-year-old Doberman lose some weight?
A—If he has not been examined by your vet in the final six or eight months to make certain he is in excellent shape, that`s move No. 1. This is especially significant if he has symptoms other than obesity such as dry skin or excessive shedding or if he tires extremely easily. Obesity can be caused by hormone imbalances.
Once it`s confirmed that he is in excellent health, eliminate every table scraps and in-between snacks.
Second, measure the quantity of dog food he`s getting so you know exactly how much he is being fed.
Third, reduce that quantity by one-half to one-third, depending on how severely overweight he is.
For example, if he`s now getting three cups of dry food and one can of dog food a day, give him two cups of dry food and half a can a day. This is done best by breaking it into two meals.
Fourth, a excellent endless stroll at least twice a day is significant. If possible, take him someplace where he can be off leash legally and let him retrieve a ball or a Frisbee.
Q—I own a year-old inactive, but not overweight, poodle.
For the final few weeks, he has had symptoms of a slipped disk. It is a grand effort for him to climb the stairs, he does not put any pressure on his back left leg, and he limps around on three legs. He has been to the vet, and she said there is nothing she can do for him. What should I do?
A—Most dogs with slipped disks will be incapacitated equally on both back legs or will own one leg worse than the other, but both legs definitely are involved.
Your dog needs to own the problem clearly diagnosed. This might be accomplished with a thorough exam and X-rays. If they do not clarify the problem, it may be necessary to own a myelogram, which involves injecting a dye into the spinal column.
If he has a slipped disk, medication may control it, although surgery may be necessary.
By medication I am referring to pain relievers, muscle relaxants or anti-inflammatory drugs.
Ask your vet for a referral to a veterinary surgeon for further diagnosis, or go to the nearest veterinary college.
Q—What are your theories on »stomach bloat» or »twisted stomach»? I recently lost my year-old German shepherd because of this.
What is the cause? Are there any warning signs, such as changes in bowel movements? Is it always fatal? Does age or breed own anything to do with it? A—The medical term for bloat is gastric dilation/volvulus complicated. It`s generally fatal within hours after it starts. Worse yet, there are no changes in bowel movement or any other warning symptoms.
Unless it`s treated quickly, it is almost always fatal within two to four hours. This allows extremely little time to get the dog to the veterinarian. Only the vet can attempt to alleviate the problem by passing a tube into the stomach to relieve the abdominal pressure, and surgery generally is required. The dog also must be treated for shock with intravenous fluids and istration of a steroid and an antibiotic.
This killer illness most commonly strikes any breed of large, deep-chested dogs.
It`s not specific about age, but it seems to prefer male dogs. Extremely little if anything is known about its cause. Some possibilities are the anatomy of deep-chested dogs, bacteria in the stomach causing gas, overeating, overdrinking, too much activity before or after meals, or trauma caused by changes in routine and environment.
Dr. Huntington welcomes questions from readers. Although she cannot reply to them individually, she will answer those of general interest in this column. Record to Dr.
Huntington, c/o The Chicago Tribune, N. Michigan Ave., Chicago, Ill. If your pet`s problem is urgent or an emergency, consult your vet.
Your dog’s eye(s) can become inflamed for a variety of reasons, ranging from conditions that are simple to repair to some that are extremely serious.
Some of the most common are:
- Foreign body: a foreign object in the eye, even eyelashes, can cause the eye to be irritated
- Glaucoma: a much more serious condition caused by increased pressure within the eye itself
- Allergies: as with us, our pets can suffer from allergy-induced itchy, watery eyes
- Conjunctivitis: the mucus membranes of the eye become inflamed and itchy (This is the most common eye problem among our four-legged friends.)
- Scratched cornea: a scratch on the eye can develop into a more serious condition, such as an ulcer
- Entropion: when the eyelashes are turned inward instead of outward, causing the eye to tear, become irritated, and ultimately infected, if not treated
There are numerous less common eye conditions that can cause eye inflammation.
Your veterinarian will work to identify what is troubling your teary-eyed friend.
The most common sign your pooch’s eyes are irritated is redness. Additionally, she may blink or squint excessively, hold her eye closed, rub or paw at her eye, and her eye might tear a lot. There may also be some mucus or pus-like discharge around your dog’s eye(s).
If you ponder your pet’s eyes are irritated, you should contact your veterinarian for advice. Numerous of the most common situations need medical attention in order to get better. Your veterinarian will most likely act out a finish ophthalmic examination to determine the cause of the inflammation.
In more serious situations, they may send you to a dog eye expert, also referred to as a veterinary ophthalmologist.
Your veterinarian will advise you regarding the best way to care for your pet’s eye(s). One of the most common treatments is to apply medicated drops or ointment to the affected eye. Having your compadre sit still while you apply the medication can be challenging. For assist with this, watch an expert apply eye drops to a dog.
Because there are so numerous diverse causes of eye inflammation, there is no single prevention that works for every situation.
To assist your dog reduce the risk of eye problems, check her eyes daily for any obvious signs of irritation, such as redness or tearing.
If you own any questions or concerns, you should always visit or call your veterinarian – they are your best resource to ensure the health and well-being of your pets.
One of the most common medical complaints that we see in our office is dogs with skin infections, “hot spots”, or allergic dermatitis, also known as atopic (atopy) dermatitis.
Unlike people who react to allergens most commonly with nasal symptoms and/or hives, dogs react with skin and/or gastrointestinal problems.
This is because there are a higher proportion of mast cells, which release histamines and other vasoactive substances in the face of an allergic challenge, in the skin of dogs. These problems may range from poor jacket texture or hair length, to itching and chewing, to boiling spots and self-mutilation, gastrointestinal pain and discomfort, diarrhea, and flatulence. Allergies may also frolic a part in chronic ear infections.
The most common causes of canine allergic dermatitis are flea allergy, food allergy, inhalant or contact allergy, and allergy to the normal bacterial flora and yeast organisms of the skin. To make matters more hard to diagnose and treat, thyroid disease may add to the problem as well.
Canine atopic dermatitis (allergic dermatitis, canine atopy) is an inherited predisposition to develop allergic symptoms following repeated exposure to some otherwise harmless substance, an “allergen”. Most dogs start to show their allergic signs between 1 and 3 years of age.
Due to the hereditary nature of the disease, several breeds, including Golden Retrievers, most terriers, Irish Setters, Lhasa Apsos, Dalmatians, Bulldogs, and Ancient English Sheep dogs are more commonly atopic, but numerous dogs, including mixed breed dogs can own atopic dermatitis. Atopic animals will generally rub, lick, chew, bite, or scratch at their feet, flanks, ears, armpits, or groin, causing patchy or inconsistent hair loss and reddening and thickening of the skin. The skin itself may be dry and crusty or oily depending upon the dog. Dogs may also rub their face on the carpet; ear flaps may become red and boiling. Because the wax-producing glands of the ear overproduce as a response to the allergy, they get bacterial and yeast (Malassezia ) infections of the ear.
In order to overcome these frustrating symptoms, your veterinarian’s approach needs to be thorough and systematic.
Shortcuts generally will not produce results and only add to owner frustration and canine discomfort.
Inhalant and Contact Allergies
Substances that can cause an allergic reaction in dogs are much the same as those that cause reactions in people including the pollens of grasses, trees and weeds, dust mites, and molds. A clue to diagnosing these allergies is to glance at the timing of the reaction. Does it happen year round?
This may be mold or dust. If the reaction is seasonal, pollens may be the culprit.
Numerous people don’t suspect food allergies as the cause of their dog’s itching because their pet has been fed the same food every its life and has just recently started having symptoms.
However, animals can develop allergies to a substance over time, so this fact does not law out food allergies. Another common misconception is that dogs are only sensitive to poor quality food. If the dog is allergic to an ingredient, it doesn’t matter whether it is in premium food or the most inexpensive brand on the market. One advantage to premium foods is that some avoid common fillers that are often implicated in allergic reactions.
This type of reaction generally is not to the flea itself, but rather to proteins in its saliva.
Interestingly enough, the dogs most prone to this problem are not dogs who are constantly flea ridden, but those who are exposed only occasionally! A single bite can cause a reaction for five to seven days, so you don’t need a lot of fleas to own a miserable dog.
Bacterial hypersensitivity occurs when a dog’s immune system overreacts to the normal Staphylococcus (Staph) bacteria on its skin. It appears that bacterial hypersensitivity in the dog is more likely to happen if other conditions such as hypothyroidism, inhalant allergy, and/or flea allergy are concurrently present.
Bacterial hypersensitivity is diagnosed through bacterial culture and examination of a biopsy sample. Microscopically, there are certain unique changes in the blood vessels of the skin in bacterial hypersensitivity.
Allergy testing is the best diagnostic tool and the best road to treatment for dogs that are suffering from moderate and severe allergies. There are several diverse testing methods available. The most common is a blood test that checks for antigen induced antibodies in the dog’s blood.
Intradermal skin testing may also be performed. In this method of testing, a little quantity of antigen is injected into a shaved portion of the dog’s skin. This is done in a specific pattern and order so that if the dog shows a little raised reaction, the offending antigen can be identified. After a period of time (hours), the shaved area is examined to detect which antigens, if any, created a reaction. Allergy testing is performed to develop a specific therapy for the allergic animal.
Numerous medicated shampoos own compounds in them that are aimed at soothing injured skin and calming inflammation.
In addition, frequent bathing (weekly to every other week) of the dog can remove allergens from the hair jacket, which may contribute to skin allergy flare-ups. The medicated baths we recommend are those that actually contain antimicrobial and antifungal agents as well as ingredients that permit the skin to be bathed on a more frequent basis without drying it out. Application of a rinse afterwards also helps to prevent drying out of the skin and hair coat.
Antihistamines can be used with excellent safety in dogs.
About one third of owners report success with antihistamines. These medications tend to own a variable effect between dogs. For some allergic dogs, antihistamines work extremely well in controlling symptoms of allergic skin disease. For other dogs, extremely little effect is seen. Therefore, a minimum of three diverse types of antihistamines should be tried before owners give up on this therapy. Examples of antihistamines commonly used for dogs include Benadryl, Chlortrimeton, Atarax, Claritin, Zyrtec, and Clemastine.
However, antihistamines are considered to be worth trying in most cases since the side effects associated with antihistamines is low, and they are typically inexpensive medications.
Antibiotics and Antifungal Medications
Antibiotics are frequently needed to treat secondary skin infections. Anti-fungal medications are frequently needed to treat secondary yeast infections.
For dogs with this problem, a strict flea control regime must be maintained.
The best flea control options include the use of products such as Advantage, Revolution, Frontline, Comfortis, and Sentinel.
The Omega-3 and Omega-6 essential fatty acid supplements work by improving the overall health of the skin. These fatty acids are natural anti-inflammatory and anti-oxidative agents. They reportedly are helpful in 20% of allergic dogs. My own experience puts this figure a little higher. They are certainly worth a attempt because they are not harmful and own virtually no side effects. Omega-3 fatty acids are found in fish oils and omega-6 fatty acids are derived from plants containing gamma-linolenic acid (GLA).
These supplements are diverse from those sold to produce a glossy jacket. Products that contain both omega-3 and omega-6 fatty acids include Allergen Caps and Halo.
Allergies develop through exposure, so most hypoallergenic diets incorporate proteins and carbohydrates that your dog has never had before. As mentioned previously, the quickest and best way to determine which foods your dog may or may not be allergic to is through diagnostic allergy testing. As dairy, beef, and wheat are responsible for 80% of food allergies in dogs, these items should be avoided.
Novel protein sources used in hypoallergenic diets include venison, egg, duck, kangaroo, and types of fish not generally found in pet food. Carbohydrate sources include potatoes, peas, yams, sweet potatoes, and canned pumpkin.
Hydrolyzed protein diets are diets in which the protein source has been synthetically reduced to little fragments. The theory behind feeding a hydrolyzed protein source is that the proteins in the food should be little enough that the allergic dog’s immune system will not recognize the protein fragments and will not mount an immune response resulting in an allergy.
Most pets with food allergies reply well when switched to a store-bought hypoallergenic diet, but occasionally an animal suffers from such extreme allergies that a homemade diet is the only option.
In this case, the diet should be customized with the aid of a veterinarian.
Corticosteroids and Immunosuppressive Agents
Cortisone products such as prednisone, prednisolone, and dexamethasone reduce itching by reducing inflammation. These medications are not without side effects, so they need to be used judiciously in treating skin allergies. Steroids should be considered only when the allergy season is short, the quantity of drug required is little, or to relieve a dog in extreme discomfort. Side effects can include increased thirst and appetite, increased need to urinate, and behavioral changes. Long-term use can result in diabetes and decreased resistance to infection.
In some dogs, endless term, low-dose alternate day therapy is the only management protocol that successfully controls the atopic pet. This protocol should be used only as a final resort after every other methods own been exhausted to avoid the potential long-term complications of the medication.
Cyclosporine (Atopica) is a medication, which seems to be fairly effective at reducing the inflammation associated with skin allergies and calming the immune system of the affected dog. However, the pricing of cyclosporine may be prohibitive for larger breed dogs.
Allergy shots are extremely safe, and numerous people own grand success with them; however, they are extremely slow to work.
It may be six to twelve months before improvement is seen. Once the allergens for the dog are identified, an appropriate immunotherapy is manufactured for that specific dog, and treatment can start. After the offending antigens are identified, then a mixture of these antigens can be formulated into a hyposensitizing injection. Depending on the type of agents used, these injections will be given over a period of weeks to months until the dog or cat develops immunity to the agents. After initial protection, an occasional booster may own to be given.
If you know which substances your dog is allergic to, avoidance is the best method of control.
Even if you are desensitizing the dog with allergy shots, it is best to avoid the allergen altogether. Molds can be reduced by using a dehumidifier or placing activated charcoal on top of the exposed dirt in your home plants. Dusts and pollens are best controlled by using an air cleaner with a HEPA filter. Air conditioning can also reduce circulating amounts of airborne allergens because windows are then kept closed.
Healthy skin and a normal hair jacket are the results of numerous factors, both external and internal. There are several glands in the body responsible for the production of hormones that are vital for the regulation of other body functions as well as a normal skin surface and hair jacket.
Hypothyroidism may result in poor skin and hair jacket, including hair loss or abnormal hair turnover, dull or brittle hair, altered pigmentation, and oily or dry skin. A blood test is a simplest and most direct way to tell if your dog is hypothyroid. Thyroid testing may include every or part of the following:
Baseline T4 Test or Entire T4 (TT4): This is the most common test. Dogs with a failure of the thyroid gland will own a lowered level of the T4 hormone. However, there are other conditions that can cause the T4 to decrease, so if this test comes back positive for hypothyroidism your vet should recommend an additional blood test, either the T3 Test or the Baseline TSH test.
Baseline TSH Test: Measures the level of Thyroid Stimulating Hormone.
In combination with the T4 or T3 test, it provides a more finish picture of the hormonal activity of your dog’s thyroid gland.
Free T4 by RIA (radio immunoassay): The Free T4 test using RIA techniques does not appear to be more or less precise than the above TT4 test.
Free T4 by ED (equilibrium dialysis): This test may provide more precise data on the level of T4 hormone in your dog’s bloodstream.
Baseline T3 Test: In combination with the T4 or TSH test, these two blood tests can give a clearer picture of the hormone levels found in the bloodstream. This test is not dependable when used alone. The T3 Test should always be given in combination with one of the other blood tests.
TSH Response Test: In this test, the veterinarian takes an initial measurement of the thyroid hormones in your dog’s bloodstream and then injects Thyroid Stimulating Hormone (TSH) into the vein.
After 6 hours, a blood sample is drawn and the level of T4 is checked. If your dog has hypothyroidism, the level of T4 will not increase even after the TSH is injected. This is an expensive test and is being used less often due to decreased production by the manufacturers.
Hypothyroidism is treated with a daily dose of synthetic thyroid hormone called thyroxine (levothyroxine). Blood samples will need to be drawn periodically to assess the effectiveness of the dosage and make any adjustments necessary.
Successful management of the atopic, allergic dog is sometimes complicated and frustrating because multi-modal management is necessary in the majority of cases to control the allergic flare-ups.
Proper diagnosis by a veterinarian and owner compliance and follow up care is essential to maximize the chances of curing or at least controlling the severely affected allergy patient.
The term hypoallergenic dog breed is commonly used to refer to a dog breed (or crossbreed) that is more compatible with allergic people than are other breeds. However, prominent allergen researchers own claimed that there is no basis to the claims that certain breeds are hypoallergenic and, while allergen levels vary among individual dogs, the breed is not a significant factor.
