He set up camp for himself right next to a main road. He was so terrified we had to trap him.
He's extraordinarily wary and mistrusting with humans even at today's date, but he's not aggressive and he doesn't attack. It's impossible to stroke him, though. As soon as you approach him he runs to the other end of his kennel. He does not walk on the lead, but he runs free every day with his mates in the yard. He's indifferent to other dogs.
It may be that the shelter is his final home.
His heartworm test result on 21st October 2020 came back negative.
