i am new and i have only had pete for about 3 months he is almost nine months and he drinks alot!!! of water i read in all of the books to take it away at a certain time but he will just sit and drink and then have to pee. He has drank so much that he has thrown it up. i have been to the vet three times and he had kennel cough at first so he had been sick they have tested him for a bladder infection and he was fine. just curious how much should he be drinking?
