Well the vet rang a few hours ago and spoke to my dad, said the orthopaedic surgeon would charge at least £500, but he was going to send him the x-rays to find out more, so will hear back either this afternoon or tomorrow morning. My dad forgot to ask about pain relief so I rang the vets back straight away, but the receptionist said he was with a patient, but would get him to phone back. It's been almost 2 hours I think and he hasn't yet, so will ring again.
