I really appreciate the kind words and support. I know that it's been a lot to throw at the poor little guy at one time, and all things considered, I'm sure he's doing as well as can be expected. We did spend some one-on-one time clicker training today and did lots of practice with him staying in the crate for a few minutes at a time. At one point, I had him crated for about 20 minutes with the door open and me in the room, and things almost felt like normal! He got a greenie for that.
We'll hang in there - not much choice in that anyway! And I'm glad that I didn't board him, considering the icy weather in Texas right now. At least we're cozy inside a house here, and he gets to be around us while we work.
We've got another business trip here coming in March - this time for about a month, but it should be the last one for a good long time. Urggh...
