‘Dog Dust’ May Combat Allergies and Asthma

“Exposure to “dog dust,” or the dried flakes of skin that fall from Fido, may protect against developing allergies and asthma in later life by altering intestinal bacteria, a new study in mice suggests.

The dust appears to contain bacteria that, when present in an animal’s gut, affects the production of immune cells in the animal’s airway.

…..

Past research has shown that exposure to pets, particularly dogs, during infancy may prevent people from developing allergies, and other work has found that bacteria in the gut can affect allergies and asthma. The new study adds to the research because it links these ideas — showing that the reason exposure to dog dust may prevent allergies is that the dust affects the population of gut microbes.”
