Just an update...
Ickey was hitting the Potty Paper 98% of the time on his second day.
(That may be a residual from the Breeders training)
And on the third day, he was pushing through the Doggy Door, just like my big guys do. (monkey see monkey do, I think) It's REALLY nice to have Roll Models !
I have a large (securely fenced) back yard, and he is moving around it like he owned it (all of it). Same attitude as my other two had/have.
All in all, He's going to be a real contribution to our Pack, and I'm SO glad I got him.
