Thanks @downandlonely. When I said goodbye to the last one, I had to go to work after that and my boss made me go home for a few days. I'm at home most of the time now, so that should be helpful. But when it's just me an my other dog, it's going to feel very empty. The vet office had lots of information about all of this, but nothing for me, so I'll need to find something to help. I wonder what to do with my other dog? I wonder how she will handle it. She's already spending the day near him, so I suspect she might know what's happening.

Thanks again.
