Hi, I have been potty training with one of those little plastic pools with newspaper in them. The Breeder whom i got Otto from trained him to go in that. Works perfectly. In the beginning I had to sense when he was going to go and i would have to put him in. A few days ago he was able to jump in on his own. So he knows to use the pool. The Question I have is how do I transition him from the pool to a place outside? I don't really have a yard, but we do have a doggie park 3 houses down. I havent taken him there because I want him fully vaccinated first. So i have a month or so before he will be. Anyone else ever potty train a dog this way? Thank you...
