Peeing all the time, UTI is cleared.

I have a 9-16 week old puppy (not one vet has been in agreement on the age and between him and his litter mate that a friend has, they have seen 7 different doctors across 4 different clinics) that is still peeing EVERYWHERE. We’ve had him for 3 weeks now.

Since the day we brought him home, he has urinated every 10-15 minutes MINIMUM. We’ve had him checked for a UTI (he had one) and it’s now been cleared for almost a week. However, his frequency of urination hasn’t slowed at all. We kennel him at night, we take him out constantly, we monitor/limit his water intake, we kennel him if we can’t keep a constant eye on him, etc.

He never goes away from where he’s at to pee. He doesn’t sniff, walk around, or show any indication that he needs to go. He will just go right where he’s standing. He can be laying on the couch with us, will stand up, and will pee before we can even reach to grab him. He actually peed 3x in the ten minutes it took me to type this and once was on my leg while he was laying in my lap.

We easily clean up 50 puddles of pee a day. He’s a medium breed dog (currently 8lbs, estimated to be ~30 full grown) and the puddles are about 3-5mL each time.

He’s the 6th puppy I’ve had this young, so I’m not a stranger to potty training. I’ve just never had this much trouble. Even my chihuahua was easier to potty train at this age (she was 1lb as a puppy) than he’s been. I’m at my wits end and don’t know what else to do.

I will be taking him to the vet again to make sure he isn’t developing another UTI, but he was clear 4 days ago at his recheck.
