ST. LOUIS, MO (KTVI)– Doctors at St. Louis University say dogs may not only be “man’s best friend”, they may keep children from developing asthma and allergies later in life.

Researchers exposed mice to dust from a dog owner’s home then tested the mice’s immune response to a substance that commonly triggers asthma attacks.

The mice exposed to the dust did not have as severe of an allergic reaction, as the mice not exposed to it.

Doctors say the exposure teaches your immune system how to react.

Findings appear in the “Proceedings of the National Academy of Sciences.”
