A Hypoallergenic dog breed is a dog breed (or crossbreed) that is more compatible with allergic persons than other breeds.

Contents

Background

The significant allergens are proteins found in the dog's saliva and dander.[1][2] Production of the allergen, and therefore human allergenic reaction, varies by breed.[3][4][5][6][7]

Also, 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.[8] But protein expression levels play a major role and amount 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.[9] How hypoallergenic a particular dog is for a particular person may vary with the individual dog and the individual person.[10]

If a person is allergic, they may be best able to tolerate a specific dog, possibly of one of the hypoallergenic breeds. Dr. Thomas A. Platts-Mills, head of the Asthma and Allergic Disease Center 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 think there really are differences in protein production between dogs that may help one patient and not another," Dr. Platts-Mills said.[10]

All dogs shed, and all dogs produce dander and saliva in some degree.[11] As noted above, the amount of the allergenic protein present on the dander and in saliva varies by breed. Also, the amount of the allergen can be reduced or eliminated in individual dogs by treatments such as bathing.[12][13] But for most breeds, when not regularly bathed, even a dog who sheds very little or has little dander can trigger a reaction in a sensitive person.[14]

Effect of size

Size may be a factor in determining hypoallergenicity. It is possible that the total body surface area of the dog is more indicative of reduced production of allergens than its breed.[15]

Smaller dogs will also leave fewer environmental pollutants containing dog dander and dog allergens (reduced fecal matter, urine and saliva). Small hairless dogs may be less likely to cause allergic reactions "because it's so easy to bathe them and the dander falls off them."[16] Dogs may leave behind urine, saliva and fecal matter as allergen sources.[17][18][19] Dogs with access to the outdoors may introduce outdoor allergens such as mold and pollen with larger animals tracking in more of these allergens.[20] It is well established that most individuals with dog allergy also suffer with additional environmental allergies.[21] 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.[22]

Effect of barking

Excessive barking may also contribute to higher levels of allergen dispersal, as saliva and dander are projected from the animal during barking. Thus, many small breeds that are known for excessive barking may not be ideal, despite their smaller total body surface area. Those with dog allergy sensitivities seeking to adopt may wish to identify a small dog with a calm temperament.

Expert recommendations

Researchers have shown that frequently bathing dogs reduces the amount of allergen related protein on the fur or hair of the dog and the amount of airborne allergen.[13] Bathing a dog at least twice a week will minimize or even eliminate the reaction of an allergic person to a dog.[12]

Frequent cleaning and vacuuming of the home, using air filters, restricting the dog to certain rooms, and adopting a small dog that can easily be given frequent baths are all recommended by the Humane Society of the United States to control allergens.[23] Scientific research has repeatedly shown that good cleaning practices in the home remove allergens from the environment.[13][24][25][26]

Many allergists suggest that a dog not be introduced to the environment of a dog allergic individual. There is some concern that continued exposure may lead to asthma. While "allergy shots" can reduce many individuals dog allergic reactions, the most common approach remains avoidance.

There have been recent studies suggesting early introduction of pets to home may reduce the likelihood of developing sensitization.[27] 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 particular allergic pet owner can tolerate a specific dog of that breed.[10]

Examples

The list below cites dogs considered hypoallergenic allergens based on shedding and barking.

Breed name Details
Affenpinscher Doesn't shed[28]
Basenji Short hair no shed and dander is a minimum with this medium sized breed
Bedlington Terrier Doesn't shed[29]
Bichon Frisé Recommended by AKC for allergy sufferers. Does not shed. Hair will come out when brushed or combed.[29]
Bolognese Doesn't shed[28]
Bouvier des Flandres Recommended by the UK Kennel Club as a breed that does not moult.[30]
Chinese Crested Has very little fur, doesn't shed much[29] but still produces saliva and dander
Coton de Tulear Doesn't shed[28]
Dandie Dinmont Terrier Doesn't shed[28]
Greyhound Short hair, single coat
Havanese Doesn't shed[28]
Irish Water Spaniel Doesn't shed[29]
Italian Greyhound Short hair, single coat[31]
Kerry Blue Terrier Single-coated, short hair, sheds less[29]
Maltese Doesn't shed [29]
Peruvian Inca Orchid No hair[29]
Pomeranian Minimal dander due to small size [29]
Poodles of all sizes Recommended by AKC for allergy sufferers. Doesn't shed. Low dander.[28]
Portuguese Water Dog Doesn't shed[29]
Puli Doesn't shed[28]
Samoyed No dander[32]
Schnauzers of all sizes Short hair, sheds less.[29] However, the breed is known for excessive barking, [33] and barking can distributes the dog's saliva in the environment
Shih Tzu A Shih Tzu has two coats of fur, with the bottom coat shedding into the top coat rather than off of the dog entirely; as a result, this breed sheds very little in the conventional sense. With regular brushing and bathing, shedding can be reduced to almost nothing. As they shed so lightly, Shih-Tzu are considered to be one of the breeds more suitable for people with allergies.
Silky Terrier Recommended by AKC allergy sufferers. Does not shed. Hair will come out when brushed or combed. However, among the worst breeds for excessive barking, which thus produces saliva and dander. [33]
Soft Coated Wheaten Terrier Doesn't shed[28]
Welsh Terrier Doesn't shed
Xoloitzcuintli No hair[29] but still produces saliva and dander
Yorkshire Terrier Recommended by AKC allergy sufferers, along with some other breeds. Doesn't shed. Low dander.
