WHAT DOES THIS MEAN?
If your dog seems to be constantly chugging away at the water bowl, especially if he isn’t doing anything strenuous to need such rapid water intake, that is a tell-tale sign that there could be a serious underlying medical issue. Three major issues associated with excessive drinking can point to kidney failure, diabetes, or Cushing’s Disease.
HOW DO I KNOW IF THE DRINKING IS CONSIDERED EXCESSIVE?
If your dog can not seem to quench his thirst, and makes more than usual stops to the water bowl you will notice a consistency in this behavior if there seems to be a problem. If your dog, however, is on the medication Prednisone, one of the indicated side effects is extreme thirst, and in this case the excessive drinking is normal. If you are unsure, call your local veterinarian and ask about your specific breed, giving details about the frequency of drinking for further advice and information.
