There are too many types of skin allergies to cover here. Briefly – skin allergies can develop as a result of a number of different reasons, from stress, diet. disease, food additives, food intolerance, and topical irritants such as chemicals used in the home, grass, pollens, fabrics (e.g. wool, nylon), plastics, dust mites, flea bites, the list goes on.
It all comes back to the dog’s immune system, and if that is comprised in any way, due to illness or the immune system is under-developed or immature, then the puppy or dog will be unable to effectively fight off infection.
When allergens are inhaled, ingested or come in contact with the dog’s body, they cause the immune system to produce a protein called IgE, which attaches itself to ’tissue mast’ cells located in the skin, releasing various irritating chemicals such as histamine.
Breeds of dog most commonly predisposed to suffer from skin allergies include, but are not restricted to:
Terriers including Westies, Scotties, Cairns, Fox Terrier (wire hair); Cavaliers, Llasa Apsos, Golden Retrievers, Huskies, Dalmations, Setters, Bulldogs, Pugs, Miniature Schnauzers and various cross or ‘designer’ breeds.
