Dog Allergy Dogs have a number of allergy-provoking protein particles in their saliva and skin scales. A dog's lick may set off a severe allergic response, as can breathing in the allergen particles. With rabbits, rats, mice, hamsters and guinea pigs the most important sources of allergens are the saliva and urine. Once dry, these secretions become airborne and can be a source of allergic sensitisation for children and laboratory animal workers. Horse and cow skin scales can be allergenic to those exposed to them.
Birds carry allergy-provoking mites, moulds and pollen on their feathers.
Budgie droppings can release proteins into the air which induce insidious lung problems and asthma. Tropical fish may be problematic, in that individuals can develop allergies to the ant's eggs upon with the fish feed, and moulds that may grow in the fish tank. Even the Cockroach, although not considered a pet, is also a 'source' of domestic allergic sensitisation. Treatment Finally, when avoidance is not possible or can only be partly accomplished, medication may be needed. Oral antihistamines and topical sodium cromoglycate or corticosteroids can be used when nose and eye symptoms occur, while bronchodilators and inhaled sodium cromoglycate or corticosteroids can be used to control asthmatic symptoms.
