Maybe this isn't OT, since dogs live in homes? Why do dogs scrach their side with their hind leg?
Is it only because of fleas or do they itch like people? Either way, what do they do about scratching their back and belly etc?
I ask because there is a puppy on Friday's rerun of Monk who is scratching his side with his hind leg and I wonder if they trained him to do that or if they put some fleas on his side to get him too. And how could they train him unless he had some reason to do it in the first place? He looks too small and young to know English already.
