My dog has a UTI and strains to pee. Is his bladder blocked?

Updated On September 23rd, 2025

Pet's info: Dog | Greyhound | Male | neutered | 3 years and 3 months old | 78 lbs

My 3yo male greyhound was diagnosed with a UTI earlier this morning. He is drinking a whole lot of water, which I know is good, but he is having a hard time letting much out when he urinates. I'm concerned about his bladder getting too full and not being able to fully void. When should I start to worry?

A UTI can cause frequent urination but does not cause a pet to not be able to urinate. They can go frequently and produce urine and then strain but the bladder is usually small due to frequent voiding. If your pet is straining to urinate and not producing any urine then this is a much different scenario where obstruction would be a concern. How was the UTI diagnosed as these are more rare in neutered male dogs? Urinalysis? Urine culture? Other considerations would be stones, a prostatic issue (although your pup is neutered and young), or a urethral issue. Did your vet feel that the bladder was large on palpation? If so this is atypical with a UTI. If you feel that your pet is not urinating a recheck is warranted to rule out obstruction as this can be an emergency if present. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
