Study links asthma risk to dogs, not cats

I feel like I have a built-in radar for dog versus cat stories. Or rather, I’m sort of a magnet for them. I know it drives some Bark readers crazy—those who don’t feel a need to make comparisons and think I should stop feeding the feud. Well, if you are such a high-minded egalitarian read no further. If you’re with me (and keeping score), add a hash mark to the “Cat’s rule” side of the ledger.

 

A recent study, led by Dr. Chris Carlsten of Vancouver General Hospital in British Columbia, Canada, revealed a three-fold increase in the risk of asthma for children who were exposed to high levels of dog allergen. According to Carlsten, the culprit may be high levels of endotoxin on dogs, a microorganism known to cause inflammation in the lungs. Meanwhile, neither cat nor dust-mite exposure seemed to increase a child’s asthma risk. I wonder if parents who read the study will opt for cats when Susie and Jimmy start begging for a pet? (A big meow to our friends over at PawNation for this story.)
