The basics: We think our puppy is about three months old; he was rescued off the street by another family, but they didn't have the time to devote to him and their two small kids, so we took him on about a week ago. The first family had him for about six weeks, and they crate trained him pretty well - we still have the occassional accident, but he's pretty good about going in the yard.
A little too good. He will not go potty of any sort when we are out on walks or visiting friends. Yesterday, we took him on a playdate with two grown dogs at a friend's house. (We think he was separated from the litter way too early, and we're doing our best to introduce him to other dogs to play.) With the walk to and from our friend's, we were out and about for around four hours. That included a little walk with our friend and his grown male dog, who marked territory every block or so. Still, our pup held it in until we were back, inside our gate, where he relieved a very full bladder.
How can we teach him that it is OK to go potty outside of our own yard? I'm worried about what would happen if we take him away for a day trip, or even an overnight.
THANKS
