Hi there. There are quite a few different things that can cause increased water intake in middle-aged and older dogs, including diabetes, Cushing's disease, or chronic kidney disease. I would recommend taking Hailey to the vet for an exam when you are able to. He/she can do blood work and a urinalysis to help diagnose the problem and get her started on appropriate treatment depending on what is found.

    Increases in drinking and urination can happen with a few different diseases. The first thing I would want to rule out is a severe organ disease (i.e. kidney or liver failure), or a condition like diabetes, or Cushings disease. This can also happen if Zoey is on a steroid medication like prednisone. If she's not on any steroid medications, then it's best to have her evaluated by a veterinarian as soon as possible to prevent potential life-threatening complications. The sooner the problem is diagnosed, the better the chances are that it will be treated appropriately. I hope that helps and all is well with Zoey.
