2 months ago we adopted a former stray from a shelter that is 2. He’s fiesty but sweet but whenever we pick him up ( even to move him gently) he will immediately go after the person who has picked him up attacking them. He’s been cleared by the vet of anything physical so I don’t know what this is. I would think he’s playing but it’s really rough and he actually digs in. Any advice??
