Why does your dog not drink very much?

Answer 1

Mine drinks water, though if he knows that he can manipulate me to get milk instead like yours did with you, he will turn down water, just like yours did! If a dog has a chance to have anything out of its ordinary diet it will. Even if it is as simple as milk and once it starts liking milk it will keep wanting it. Basically it will keep manipulating you until you make it stop drinking milk.

Answer 2

It means he/she is getting sick if this happens to your dog Take him or her to the vet
