Daisy got her vaccination booster this evening! Thankfully she didn't even feel the needle going in and there were no hysterics! I actually forgot to ask the vet not to inject her neck but all went well.
He gave me the name of a veterinary clinic in Cork City who can do MRI scans but would need to be booked well in advance.
I'll call them and see if they still offer the service and ask how much it costs,otherwise it's the veterinary college or a trip across the Irish sea.
