My pet is drinking a lot and peeing a lot; what could that be?

Dogs and cats can drink and urinate excessively for several reasons. The source of the problem may be in the urinary tract itself, or it could be in another area of the body but be affecting the urinary tract secondarily.

The first step to diagnosing the problem is usually with a urine test. Often a blood test is also required to assess the blood sugar, kidney function and liver enzymes.

One common cause of excessive drinking and urination in older pets is diabetes mellitus. Diabetes occurs when there is a deficiency of the pancreatic hormone insulin; this results in excess sugar in the blood and the urine. These pets often have excellent appetites but will empty the water bowl in one sitting! They may even urinate in the house despite being housetrained; these pets should not be scolded. They usually can’t help it!

If you think your pet might be drinking or peeing more than normal, consult your veterinarian!

1. WE CAN NOW SEE ALL CASES BY APPOINTMENT ONLY This includes vaccines, wellness exams, blood work, spays and neuters, dental services, and more!


  • Continue our "closed waiting room" policy to protect our clients and staff. When you arrive, please remain outside the hospital and use your cell phone to call us. We will take a history of your pet's health and discuss any concerns. A staff member will then meet you outside to bring your pet into the hospital for an examination. The Veterinarian will call you to discuss the recommended treatment plan. After your appointment, a staff member will return your pet to you outside, and take care of any needed medications and payment.
  • Continue the use of credit cards as the preferred payment method.
