It may be possible to limit exposure to certain allergens. For example, exposure to house dust mites can be limited by keeping animals out of the bedrrom and using hypoallergenic matresses and pillow covers. Filtered vacuum cleaners can be used, and animals should be kept out of rooms for two to three hours after vacuuming. Soft toys harbour many dust mites and so should be avoided, or frozen for 24 hours once a month to kept the burden low. The animal's bedding should be washed at a temperature of greater than 70°C and the bed wiped out regularly with a damp cloth. Environmental flea control products are effective at killing dust mites in the home. If the animal is allergic to pollens, walking routes can be altered to avoid contact with the specific source, be it grasses, trees or weeds. Dogs can be washed after walking through vegetation to remove allergens, and lawns can be mown short.

significant improvement is controversial, although

avoidance was beneficial in canine AD (6).
