Housebreaking for us has been a bit of a mystery. Bear does not "cue". Even now, I have to be very watchful and see if he's pacing to the door or just roaming.
We had quite a few accidents previously. We actually just had one a few days ago that dumbfounded us. Bear was laying on his mat, I called him and he got up to come to me and pissed the whole way. No signs. I think it surprised him as much as me. He's almost 5 months old, now.
When he was younger (9 weeks) he peed everywhere!! It was very embarrassing. Try stoping him in the act. When he squats to pee, you can voice "no!" Or "uh uh" or clap your hands. Anything to stop the stream. Then promptly pick him up and take him outside to his potty spot. Whenever he successfully potties outside, give lots of praise and treat with a high value treat. Now Bear will squat to pee even if he just went, as soon as I say "go potty". The trainer told us housebreaking is like have two identical bathrooms, one inside and one outside. If someone bothered you every time you used the inside bathroom, you'd prefer the outside one. So you have to get your dog to think along those lines too.
Make sure your cleaning the accidents up with an enzymatic cleanser. I use diluted vinegar and let it soak for 20 mins before wiping it up. We have laminate floors, so it's easier than carpet.
Bear was only crated if a) we weren't home; b) he was supposed to be sleeping; c) I needed a break (5-20 mins max); d) he didn't potty right away during a break (10 mins then we tried again until he pottied). Other than that, Bear was either leashed to us or blocked in with an xpen so we always had an eye on him. Since he doesn't cue, anytime he started sniffing we'd rush outside to potty. I prefer out of crate time, because it gives us the opportunity to learn about each other and bond. I'm sure the crate gets tedious and boring after a while. He only gets access to certain areas of the house until recently. He's graduated and now has full run, though I prefer him to be near so if he disappears for more than a min, I'm calling him back to the living room.
Now a days his only cues are sitting at/near the door, pacing from me to the door, heavy panting in the crate, the "potty dance" where he gets all antsy and can't stand still. Is a work in progress and some dogs take longer than others. Consistency is your best friend. Sent from my iPhone using Petguide.com Free App
