So Nemo has been a dream when it comes to house training. We have only had a handful of accidents and they were all because I was slow reading the signs.
In my own defense his signs can be a little vague. Usually he sits in front of the door and sometimes he will bark. But he also likes to sit in front of the door even if he doesn't have to go out, particularly at night when he can watch the bugs.
To help make his signals more obvious, we hung a cow bell on the door knob. After we hung the bell, the next time we went outside I rang the bell before I attached his leash. The next time he had to pee he went over and nosed it himself. We were so excited that he had figured out the bell so quickly. Point goes to me.
The bell worked great for about two days and then it clicked in his head that "hey if I ring the bell I get to go out, even if I don't have to pee." After the 5th trip out in a 15 minute period I knew I had created a monster and would have to modify the training. Point goes to Nemo.
The downside to the bell is that in order for it to work, I have to always put him out, even if I know he doesn't have to go. If he doesn't trust that it works, he won't use it anymore. So the training modification has to get him to understand that it only works for potty time and not play time.
Training Modification Attempt 1: Every time he rang the bell, I would immediately take him out, directly to his pee spot, I would stand and not move. No wondering, no playing, no sticks. If he didn't go within a minute or so I would take him back in. After about 20 iterations in about 30 minutes, his patience won out over mine. He seemed quite content to just sit there and stare at me. Point goes to Nemo.
Training Modification Attempt 2: We set up a run at the back door. Every time he rings the bell, I attach him the the run and leave him to his business. He seems to dislike being alone so he will pees quickly and chases me back into the house within minutes of putting him out. This has greatly reduced the bell ringing in the house while still getting him to use it.
Another key to this technique is that I initiate all outdoor playtime. The only way he will get to go outside to play is if I call him over.
Hopefully this will stick. The point of failure with this technique is that it requires that he dislike peeing in the house more than being left outside alone. If he decides he would rather pee inside than go out alone, we will have to try something different. But for now, point goes to me.
