He is 10 weeks old. We take him out every 2 hours, and someone is always with him. But it seems he prefers to do his business indoors.
He may need to go out more often. I had one puppy that had to go every hour. They just lack bladder control at that age. It's a lot like having a newborn. I'm not going to lie, the first few months are rough. I would literally sleep on the couch by the back door and let my puppy out every 2 hours at night. Sometimes as soon as I heard them stir to prevent the habit of whining. During the day, I let them out more frequently. It's going to depend on their bladder control, how much water they drink, how often they play, etc. If he's still going inside after letting him out every two hours, I would start letting him out every half hour to hour. And I would stay outside until he went potty. Or I'd put him in is crate if he doesn't go potty within 10-15 minutes and repeat in another 10-15 minutes.
When he is out of his crate we are playing with him, but he will pee/poo out of nowhere without any signs (sniffing, circling etc.). However sometimes he runs off to poo, and by the time one of us has caught up to him, it's too late. My daughter tried to startle him once and even picked him up to take him out and he simply continued to go.
They will continue to go when you pick them up because they don't have the bladder control yet to stop mid stream...lol. If he's running off to pee by himself and you haven't caught up to him yet, he's being given too much freedom in the house. That's why I would anticipate him needing to go potty before it happens. If you take him out every half hour during the day, he's bound to eventually go outside. You can also tether the puppy to you so you can redirect him immediately.
There is no rythme or reason with this dog. Sometimes he even poos or pees on our mini schnauzers indoor potty..But we think he does it to drive our puppy up the wall.
LOL! Puppies don't try to intentionally drive anyone up the wall. They just do. It's part of their charm. It really is like having a newborn baby. He's only been alive 10 weeks. You have to teach him what to expect. Get rid of the smell with an enzyme cleaner (ie, Nature's Miracle) so he doesn't keep going in the same spot. At this point, he may not know it's bad to go in the house because he's not being redirected properly. And if you come own on him harshly for a basic biological need, you're going to make him go to the bathroom behind your back.
Also, you can't have an indoor potty for one dog and expect another dog not to use it when that is where they smell the urine/feces. I'm not a fan of pee pads for dogs unless you're in a high-rise. I don't like getting a dog used to going potty inside.
Compared to our 10 week old puppy, he just seems wild and untrainable. Of course they are different breeds. We are all first time dog owners so this is all new and VERY stressful. There is contradictory advice all over the internet about potty training and crate training. ?
It certainly sounds stressful because of your other responsibilities and it's not your puppy. It's your daughters. The bulk of this responsibility should fall on her. It's not fair to dump it on you when you have your own dog to train. GSD are ridiculously smart, and they do want works. But they are also a mouthy, nippy breed that needs to be taught what is acceptable. What works for one puppy may not work for another so you're going to get different advice. But most of the advice on this board is good and it's specifically for this breed.
