While it is fairly clear that single coated dogs that don't shed are best for owners who suffer from allergies, breeds that may be the worst choices are not quite as clear. Humans can be allergic to pet skin dander and pet saliva. Dogs that shed heavily, those that have wrinkled skin and dogs that drool due to the shape of their mouths top the list of those breeds and mixes not advisable for people with pet allergies.
Double Coated Breeds
Double coated breeds are dogs that possess a top coat and an undercoat that sheds multiple times per year. With shedding comes the dander that is typically at the root of the cause of most pet allergies. Some of the more popular double coated American Kennel Club registered purebreds are huskies, German shepherd dogs, golden retrievers, Pembroke Welsh corgis, cardigan welsh corgis, Shetland sheepdogs, Labrador retrievers and shih tzus.
Dogs with Skin Folds
Taking into consideration the fact that most pet allergies come from pet dander, breeds with natural skin folds need to be considered as breeds that may not be suitable for allergy sufferers. Bloodhounds, Chinese shar-peis, basset hounds, mastiffs, pugs, boxers and bulldogs are popular American Kennel Club registered breeds that tend to have wrinkles on their bodies or face. Wrinkled breeds also tend to get yeast and other skin fold infections, making them even less desirable pets for allergy sufferers.
Dogs that Drool
Since saliva can be considered an allergen for some pet allergy sufferers, dogs that drool may not be appropriate to have as pets. Most of the dogs that drool are large breed dogs that have extremely loosely formed lips. Some are also double coated and have wrinkled skin or faces, which would make these breeds far less suitable for allergy sufferers. American Kennel Club breeds to be considered are Great Danes, mastiffs, boxers, rottweilers, Saint Bernards and Newfoundlands.
