We have all heard that pets can help teach kids patience, responsibility, and empathy, but according to a recent study, having a dog in the home during childhood, especially during the first year of infancy, seriously decreased a child's likelihood of developing sensitivities to allergens like pollen. Our own Maggie first broke this story a few days ago but it's worth repeating for those thinking about investing in a canine commitment -- and for those who like photos of cute kids and cute dogs. See gallery that follows.

So the science behind this theory is that dogs bring germs inside on their coats and in their mouths, thus exposing kids to them and boosting the child's immune system. Older generations were often exposed to more dirt and germs as children (you know, because kids used to actually play outside instead of sitting indoors playing video games), and therefore developed a greater resistance to many allergens than kids today.

This study in particular has taken blood samples from 3,000 six-year-olds and will test the samples for hints that the child might become allergic to things like pet hair, dust mites, and pollen. The children will be retested at age 10, but the lead researcher has already stated with confidence that, "Our results show clearly that the presence of a dog in the home during infancy is associated with a significantly low level of sensitization to pollens and allergens."
