Probably fleas. Check for small dry dark specks on that area and if they turn red when wet with water that is dried blood from the flea.If the dog only gets the rash and or hot spots in summer months it is a good sign it is fleas. Fleas carry tapeworm larva. Not all fleas do
but there is no way to tell which ones do and don't. If the dog happens to injest a flea with the larva it will get tapeworm. Also, people can get tapeworm if they kill a flea with their fingers and happen to touch their mouth without washing their hands. So, control the flea problem before anything else.
