Of dogs, house dust and asthma…

This is a tale of how owning a dog can help protect your child from asthma.  Strange, but true.

Researcher Dr Kei Fujimura used mice to test the impact of house dust from homes where a dog lived and from those that didn’t.  She found (and her study was presented at a recent meeting of the American Society for Microbiology) that the dust from households with dogs seemed to have a beneficial effect.

Mice who were fed dust from these households developed an immune response to RSV(respiratory syncytial virus).  Infants who contract this virus have a marked increase in their risk of developing asthma.  RSV affects 90% of children worldwide.  That makes this study significant.

Dr Fujimura says these results support the hypothesis that exposure to animals in early childhood stimulates the immune system to resist the development of asthma and other allergies.

Another reason to introduce your children to the wonders of dog ownership at an early age!
