My dog suddenly drinks a lot and pees inside. Is it a UTI or diabetes?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund | Male | neutered | 16 lbs

My dog started drinking a LOT of water and can't stop peeing in the house all of a sudden. He pooped once too. He normally has no issues but he's having 2-3 accidents a day. Should I bring him in? He's an overweight dachshund I adopted 5 months ago and these issues just came on, although he's always drunk a lot of water. I'm worried he has diabetes or a UTI.

I am sorry to hear that Stanley is experiencing these issues I am sure it is upsetting for you both. Anything a dog experiences polydipia and polyuria, or an increase in water intake and Urine output, it is a good idea to have thnwk evaluated by a veterinarian. These clinical signs could be a UTI, diabetes, kidney concerns or even metabolic disorders like hypothyroidism and cushings. Your vet will be able to perform blood work and tribe analysis to be able to accurately diagnosis the problem and make a treatment plan with you.

    Hello. In an older dog, this could be an indication of some kidney problems in Foxy, a urinary tract infection, hyperthyroidism, or some other endocrine disease like diabetes. Please have Foxy evaluated at your earliest convenience to see if there is something to be concerned about. Thanks for using Petco Pet Education Center, formerly Petcoach.

    There are many diseases that cause dogs to excessively drink including urinary tract infections, diabetes, kidney disease, liver disease, Cushing's disease, Addison's disease, thyroid disease, etc. He needs to be examined by a vet to determine the cause. Your vet can run a urinalysis and blood panel to help diagnose and then determine the best way to treat.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Spud! There are many reasons for increased thirst and urination. It would be helpful to know Spud's age, for some of these conditions are more common in older animals. Causes of increased thirst and urination are: urinary tract infection, kidney and liver disease, diabetes mellitus (classic diabetes), cushings disease, addisions disease, increased calcium (cancer indicator), increased thyroid (in a dog this usually is due to thyroid cancer) and diabetes insipitis. I recommend scheduling an appointment with your Vet when they reopen. Most of the above conditions can be determined with blood work and a urinalysis, I hope this helps and I wish Spud the very best! Happy New Year!
