I have a new 9 week old puppy. I think housebreaking is going pretty well as when he starts to sniff around like something is going to happen, he does it near the door and we go out and he pees. However, we are having one weird issue. Sometimes it is like he does not finish outside and then comes back inside and pees again. I give him plenty of time outside and try not to do anything that will distract from finishing his business, but it has happened several times anyway. Sometimes, he does not pee immediately when he comes back in, but does so within 5-10 minutes. Is this just because he has a baby bladder or could there be another cause? Thanks for any input!
