Today Power had surgery to fix the tear in his skin. While he was there I got out an old sweatshirt, cut the sleeves off, and made a strap to tie over his hips . When I went to the Vet's office to pick him up, he was still sleepy, and yet he was able to walk with a bit of help. He had a rather vacant look in his eyes! The vet lifted him into my car, but when I got home to the motorhome, my friend Carol came over to help me get him out of the car and into the motorhome. I did most of the lifting, but needed help holding doors, leashes, etc. Power was a real sweety. He didn't make things more difficult by screaming, kicking, biting, or collapsing. I've had other dogs do those things.
After getting him inside, I put his sweatshirt pants on him and he tolerated them well.
I hoped that the strap over the back would keep them from sliding off, but found that after about an hour he was having them slip.
Perhaps I will be able to keep them up with a modification.
