My 6-month puppy won't poop outside & pees inside. Is it a UTI?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 5 months and 21 days old | 10 lbs

My 6 month old puppy Max won't poop outside at all anymore and pees so much more inside now then he did when I first go him 2 months ago. He was doing better with potty training at 4 months then he is now. Recently I have noticed that he is peeing a lot more & his pee is very yellow & stinky. Could this be a UTI or bladder infection? He also seems to be cleaning his potty area more often.

As far as the change in urination, I would certainly have your vet evaluate a urine sample to evaluate for a UTI. It will make housetraining much more difficult (or impossible) if there is something medical going on. So, that could certainly be a reason for the backsliding with his training. You may also check a fecal sample. One of my dogs started pooping in the house at 6 months of age, and we found an intestinal parasite was to blame. If there isn't anything medical going on, then it's time to work on housetaining. It is common that we see a little backslide in housetraining around 6 months of age because as owners we think they are doing well, so we get a little more slack in our training. I recommend going back to square one. Keep Max in a kennel or on a leash in the house so he is under very direct supervision. Take him outside immediately after eating or playing. Go outside with him and reward him for going outside. The longer Max goes in the house, the harder it will be to housetrain him, so put in the time and effort now. I hope that was helpful.
