Thanks Baz,
We have been giving him positive reinforcement and he has shown signs of coming around. He had his first vet visit on the 16th and he immediately took to a chair in the exam room so we know he like to sit up higher than floor level.
He has stepped up at home and likes personal contact with the wife.
Vet time:
Riding in the truck
Staking territory on the couch
Ignoring the new humans at 0430 getting up for work.
