I honestly don't know. I leave Alphy in one when I'm gone and at night because he potties. I thought it was because he was lifting his leg on things although I've never seen him do that. Last night I discovered he'll just pee in it. We were all cuddled up for the night and I could smell it. He never got up or anything, just layed there and peed in his band.
When I'm home I let him run around without a band, I've never caught him pottying. But there are stains around my house which I think come from when he's home with the kids and they don't take him out.
Okay, I got off track. For me, I don't think they are training Alphy at all, just protecting my stuff.
