My dog's peeing is unusual, but vet tests found no cause. Why?

Updated On September 23rd, 2025

Pet's info: Dog | Greyhound | Male | neutered | 6 years and 1 month old | 74 lbs

My dog's urination has is unusual. He will sometimes pee for a long time (several minutes), or pee multiple times in a very short period of time, or go outside to pee, then have an accident inside the house. Sometimes his urine stream is normal, sometimes it's comes in 'spurts'. Our vet has run blood & urine tests, and done an X-ray and MRI, but no cause has been found. What could be causing this, and how can we find out!?

I would make sure you vet has cultured the urine to ensure there is no infection. You could also ask them to do an ultrasound or refer you to a radiologist to do a detailed ultrasound of his bladder, urethra and prostate. I would also ask your vet if they have done a prostste exam. With Frankie being a neutered male, I am less concerned about a prostate problem but it never hurts to check. If he is drinking excessive amounts of water or if the irons looks dilute then I would also run some bloodwork to ensure all of his other values look normal. Finally, if everything looks normal then this could be a behavioral thing. And you may need to go back to basics with crate/house training. I hope this helps!
