My dog suddenly peed a lot. Is excessive urination a health concern?

Updated On September 23rd, 2025

Pet's info: Dog | Boxer | 6 years and 2 months old

Hi. Last night my dog suddenly had to go out to pee very badly. So much so that he was whining (not the norm). I took him out & he peed the longest pee he's ever done (that I've witnessed). He was fine after. Today, my dog walker commented on his report card "Cruz peed the longest pee in the world!". Otherwise everything is normal...is there something that may cause this/that I should be concerned about? Thanks!

I would not get too worried over two episodes. I recommend watching his water intake and urination over the next week or so. If you notice that both remain elevated he should get checked out by a veterinarian as it could be signs of early diseases like kidney issues and Cushing's disease. Also monitor him for any blood in his urine, dribbling, or straining to urinate as it could indicate an infection or even stones.

    Hello, and thanks for your question. A sudden and dramatic increase in urine production is always a concern, and is something that needs to be addressed by a vet as soon as possible. Increased urine production can indicate diabetes, kidney disease, Cushings disease, or another internal metabolic problem - have your dog sitter stop the carprofen until Higdon is seen by the vet, as carprofen shouldn't be given if there may be kidney disease. Your vet will likely want to look at some bloodwork and evaluate a urine sample to determine what's causing the increased urine production. I hope this helps!

    You should get him to your vet for an exam. With any abnormal urination problem an underlying medical issue should be ruled out first (like a urinary infection). If no medical problem is found, then it is likely a behavioral issue and you will need to consult with a professional dog trainer to essentially re-house train him.

    Poor Carl! There could be a medical cause behind his having to urinate so frequently, such as a UTI or bladder stones. It could also be an illness like diabetes that is causing him to have an increased thirst which then leads to the need to urinate often. I'd recommend giving your vet a call in the morning to set up an appointment for him. The vet can diagnose if he does have a medical problem causing this issue, and can discuss treatment options for him. Best of luck, I hope this helps!
