Apart from the obvious things, such as exertion or exposure to salt or excess heat, excessive drinking can be one of the first symptoms of a variety of medical problems including diabetes, hypothyroidism, Cushing’s disease, pyometra, urinary tract disorders and even poisoning. But before you jump to any conclusions you must first check to see if there are any other changes:

  • Did you change foods? Canned food contains more water than semi-moist or dry, so if your dog is eating drier foods, he will have to drink more to make up for the change.
  • Did you cut off another water source — such as, unfortunately, the toilet — so that your dog now only gets water from its bowl?

If no changes have been made, then there is a problem — one you cannot treat. You need to see your veterinarian as soon as possible.
