Hello, I'm Dr. Deb and will do my best to help you today.

I'm sorry for this concern for Addy.

There actually is quite a long list of possible reasons why a dog might consume more water:

Kidney disease

Liver disease

Diabetes Mellitus (high blood sugar)

Cushing's disease

Urinary tract infection

Diabetes Insipidus

Psychogenic (which is basically ruling out other causes)

Increased sodium in the diet

Infection in the kidneys (pyelonephritis)

Leptospirosis

Addison's disease

....and this is just a partial list.

In most cases, unfortunately, blood work and a urinalysis will be needed as a starting place to try and determine the underlying cause of a dog's increased thirst. Then based on the results, additional testing might be suggested to get to the bottom of the problem.

In some patients, it can be a challenge to determine the underlying cause. I've also seen some patients who drank more water for a short period of time but then returned to drinking a more normal amount. This isn't common but it can happen.

I hope this helps. Deb
