Thank you for all your experiences. We made it through the first week and a half and only had one short period when we weren't sure what to do with the dog. It was like the dog took crack and was off the hook bouncing off the walls for a few hours. It hasn't helped that it has rained every single day since we got the dog, and my back yard is so wet and muddy.
We bring him outside to let him run around several times a day. It's balancing act, because he loves to pick up objects and chew them, including roots, sticks, rocks, etc. Once he gets a hold of them, he is very stubborn about letting go. I just don't want him to choke on anything or ingest something harmful.
Potty training is a work in progress. We have been encouraged at times.
We also take him for a walk around the block, and when it isn't pouring rain, at a local park. Since he is so young, he is very close to the ground and sniffs EVERYTHING along the way. So we are trying to teach him to walk along with us and how to heel. It's a work in progress. He's actually a better walker than our previous dog, which was a Westie.
Over the winter I'm going to start bringing the dog into the TT to get him acclimated to it. Our previous dog wanted no part of the TT and would try to leave immediately after she went in there.
