Another Reason To Own a Dog: Linked With Lower Asthma Risk

Studies have shown that kids with dogs are less likely to develop asthma. Now a new study shows if results from mice may apply to us as well. The work was presented at the American Society for Microbiology.
[Kei Fujimura et al., "Microbes in house dust from dog-owning homes protect against a common viral infection associated with increased risk of asthma development"]
Called hygiene hypothesis, the idea is that extreme cleanliness may actually promote disease later on. The researchers collected dust from homes that had a dog, and they fed that house dust to mice. They infected the mice with common childhood infection called respiratory syncytial virus or RSV. mice who ate dog dust were protected against RSV infection symptoms like inflamed, mucus coated airways. This suggested that exposure helped them avoid the virus.
