I visited him again 4 days later. He looked the same and when I approached his kennel, he wagged his little tail. He didn't get up, but still. I got a tail wag.
I was asked by a volunteer if I wanted to take him for a walk. The home had a volunteer come with us, as security that I wouldn't try to steal the dog. Not that the thought had crossed my mind.
The walk went well. He pulled but I expected it, he was just so excited to be able to stretch his legs and have a good smell of the grass and bushes. After the walk we returned him back to his kennel and I stayed with him to talk. I chattered away and he listened the whole time.
Ii didn't want to say goodbye so soon after arriving but I had to go. The staff were looking at me more often now. Perhaps I had been here too long. It had been 2 hours since I arrived. They probably thought I was waiting for the perfect moment to grab him and run.
The thought hadn't crossed my mind.
