Animal allergies in children are similar to those in adults. The proteins found in dander shed by cats, dogs, birds and other animals can cause sneezing, a runny nose and itchy, watery eyes. Proteins in dried animal saliva, urine and blood can also trigger allergy symptoms in some children.  

Though pets are the primary source of animal allergies in children, symptoms also can arise from exposure to farm animals or proteins shed by rats, mice and other rodents. The classroom can be another source of animal allergens, because many teachers keep animals in the classroom. In addition, dander is very sticky and children with pets can bring it with them to school on their clothing.

Once a child has been sensitized to an animal allergen, families should take steps to reduce the child’s exposure to the source of the problem. While there are medications available to address allergy symptoms, the most effective way of controlling animal allergies is avoidance. This can be difficult if the animal is a pet, but failure to remove the pet from the household increases the risk that the child’s allergy will grow worse. Eventually, other health conditions such as asthma may develop.

Parents often wish to limit their child’s exposure to animals as a way to prevent allergies, but such precautions may not be effective. Additional research is needed into the connection between early animal exposure and the development of animal allergies. In the meantime, most experts do NOT recommend making pet choices based on the desire to prevent allergies from developing. Parents are encouraged to discuss their concerns regarding animal allergies with their child’s physician.
