What's a mom to do?

I'm worried about Buddy. As you probably know, if you ever read this badly-neglected blog, Buddy was attacked by some neighbor dogs on Valentine's Day. Three weeks later, still recovering from his wounds, I had to board him with the vet so I could go on a business trip. When Rob and I picked him up, his front leg was bothering him. He was limping on it, and the vet could not determine why. A week later, as the symptoms grew and changed, we finally learned that the problem was an abscess caused by an undetected bite wound (from the Valentine's Day attack). Before he knew it, Buddy was back in surgery, back in the protective collar and on lots of heavy medication again.

Last weekend, we were finally able to take the collar of shame off of him, and Buddy is 95% healed from the trauma. But now he is acting like a different dog. He still enjoys a walk, but doesn't frolic as much as he used to. He is barely interested in his food. He is drinking plenty of water, which is good. But he seems content to sleep all of the time and I have to beg him to come up on the bed. This is just not the Buddy I know.

I really think that this may be a case of depression following the big event. But I'm not sure what to do for him. Do I just let him sleep and wait for him to start feeling better? Do I get the vet involved? I hesitate going back to the vet. I just don't know what they could do for him, and I don't want to traumatize Buddy any more.

I don't how people with human children do it. My hats are off to you. I would be a basket case if this were my actual child. Still, I am kind of basket case.
