Ok...our pup is now about 9 1/2 weeks old. We brought him home at age 8 weeks. We've been working very diligently with him to house break him; we watch him like hawks and try to take him out about every 15-20 minutes and every time we take him out, he pees immediately and of course we praise him. He sleeps through the night in his crate, and I get up at 5:30, take him out and he immediately goes #1 and #2. Sounds good, right? Here's the problem: There are times when I take him out, he pees once or twice, and then I bring him back in. He'll walk around a bit, and then proceed to pee on the floor, less than a few minutes after I brought him back in! I don't get it. Could there be something wrong with him? At almost 10 weeks, a pup should be able to hold it in for more than 10-15 minutes, shouldn't he? Especially right after he comes back in from outside? When we catch him, we raise our voice, pick him up and take him out, then clean the area thoroughly. I mean, it seems like he "gets" it. Go outside, go potty. Everything else, he's catching on so fast. I say, "let's go outside" and he goes running down the stairs to the door and is ready to go. He's learned to sit (well, about 75% of the time, LOL) but the potty training, well, that's a bit frustrating right now. When I take him for his next round of shots next week, should I mention this to the vet to see if she thinks there may be something physically wrong like maybe some infection?
