We're having to rehome him whatever happened prior to us finding him has left him with a weakness in his back. He's off steriods and fine now but he can't play too rough which is all he and Tia do and the vet is worried about the risk of long term damage. We're trying to rehome him ourselves but the logistics or keeping him and Tia seperate aren't manageable long term so going to speak to some rescue centres later this week
