Not much to add, sounds like you have a good PMA. Good to hear you have the dog around for some companionship and support. W and I had to put ours down just prior to the bomb dropping. Probably part of her scale tipping. Miss that little guy a lot. She actually got me a lab 5 days prior to leaving, and I had to give her up since I was now alone and she was a pup and alone all day. Wish I could get a dog right now but between work it just wouldn't be good for the dog.
I've found in GAL that trying new things is pretty cool too. Do the dog park for sure, it is as much for the owners as it is for the dogs. I always used to meet the coolest people there.
