Sadly, we have to move him.
He needs an experienced person who can allow him time to get used to being in a home. A quiet environment would be most suitable and with a single person or a couple.
He’s not been treated well and it appears he’s been slapped at least and is head shy. You can put a lead on him no problem but he doesn’t like people to get close to his face, he will react and has done so.
Happy to share more with anyone interested in helping.
