My dog has a UTI & leaks pee when lying down. Is this normal?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 13 years and 4 months old | 43 lbs

Our 13 year old lab mix was tested and diagnosed with a UTI yesterday. She's had 2 full days of antibiotics, and her appetite is now back, but she is still unable to urinate on her own, but large amounts of urine leaks out while she's laying down. Is this normal? It's difficult with our vet's office closed for the holiday weekend. Thank you for any advice.

This is actually normal with a painful UTI. She probably does not want to urinate voluntarily because it hurts, So she just holds the urine. The urinary bladder has a safety system with pressure receptors. Once the bladder gets too full, there is a pressure build up and that activates those receptors which then make the bladder sphincter muscles relax and urine can leave the bladder before it bursts. So as soon as Carmen lies down the pressure increases, the urine flows. This should stop when there will be less pain when the inflammation goes away. This may take a few days. In the meantime , I am afraid it means wiping pee. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
