There are 8 allergens associated with dogs, they are all allergens which affect the airways.
Can f 1, 2, 4 and 6 are all lipocalin proteins. These proteins are the most likely candidate for your allergy to pet hair. These proteins transport molecules like lipids and steroids around the body.
Can f 3 is a serum albumin protein, people who are allergic to this protein are more likely to be allergic to other mammals and very rarely can become allergic to eating mammalian meats such as beef, chicken and pork, which also contain these proteins.
Allergy to dog dander is strongly associated with allergic rhinitis as well as asthma, rhinoconjunctivitis and atopic dermatitis.
A dog allergy can be strongly linked to other animal allergies due to the lipocalin proteins. There is evidence of cross reactivity due to this protein with cockroaches, cows, cats, guinea pigs, horses, hamsters, mice, rabbits and rats.
