Does the fact a dog drinks a lot of water point to any health issues?
My dog drinks more than a litre a day. He drinks until his whole bowl is empty and i have to refill it straight away. I thought it was a problem and asked the vet as i was concerned about diabetes he did a blood test and he was fine. He said that it was just the fact that he liked water. It is a good thing though that he drinks alot. If you are concerned get a blood test for the dog, it will put your mind at ease. But i am sure he is fine. This was at anytime of the year and not just in the summer. But if you have only noticed it now then it is most probably due to the heat.
