Sorry for the dumb question. I have my 3rd gsh who is exactly 1 yr old. I notice that whenever he eats and then drinks, the water is so dirty from the food he was eating. I never noticed this with my other dogs.. He is also a big drooler just as he leaves the water bowl , but never drooling after that. any ideas what he is doing different from my other dogs? Thank g-d he prefers tap water and not the bottled water that I always gave my prev gsh's.
