My Cavapoo leaks urine after peeing in heat, is it UTI or diapers?

If the antibiotics didn't make much difference, I'd be suspicious of puppy vaginitis, which is a relatively common inflammatory condition that can lead to accidents and sometimes make them more susceptible to urinary infections. It generally resolves with age. I would also check for a stricture (this may require sedation as they don't love vaginal palpation...). For now, since your vet hasn't been able to check a urinalysis, that would be the first priority. See if you can get a sample- sneak a small container under her when she squats. If you have to hold onto the sample a few hours before dropping it at your vet, stick it in the fridge, but the fresher the better. If you're having no luck, your vet can collect a sterile sample via cystocentesis. Hope this helps.

Your puppy may have a urinary tract infection. Since puppies can deteriorate very quickly (they heal quickly as well), I suggest you make an appointment with your veterinarian. He may need to be prescribed antibiotics and pain medicine.

Thank you for using Petco Pet Education Center, formerly Petcoach! While it is normal (although frustrating) to have “good” days and “bad” days while house training a puppy, the episodes you describe may be an indication of something more serious, such as a UTI. This is definitely possible if Phoebe is straining to urinate, urinating small amounts, or has reddish colored urine and if you notice her licking her vagina more frequently. If these signs continue, she should definitely be seen by a vet as soon as possible. I hope all is well!

The most likely reason at her age is a urinary tract infection, i strongly recommend taking her to your vet ASAP in order to get it checked and treated, the vet will need to perform a urine analysis, if it is positive for an infection she will need to take a course of antibiotics.

This could definitely be a sign of a UTI or a vaginitis (infection in the vagina). I would take a picture for your vet to see just in case they request it, but this isn't a requirement. I would have your vet take a look at her. They will likely run a urinalysis and start her on some meds if needed. I hope this helps!

Thank you for submitting your question regarding Hazel. Anytime you acquire a new pet, it is important to have an examination by a veterinarian. A urine sample can be tested at this time. It can be hard to differentiate puppy behavior from disease without testing the urine. Based on these results, medication can be prescribed if a urinary tract infection is found. Rarely puppies will have congenital disorders causing the urine to leak. This is rare though. I hope this information helps!

It is possible that Koa has a urinary tract infection. But at her young age it could just be that she is not sufficiently potty trained yet (which is normal for a pup her age). I would recommend having her checked by the vet. They will likely want to do a urinalysis to look for an infection.
