Out for the Count Once Again

Took Little B back to the vet this evening just to check that the wound is healing well, which it is. She prescribed some more Tramadol to sedate him but when I got back to the reception area, it appears that they can't get any! Phoned his specialist vet and am waiting to find out how to get some...... we really need it if we're to keep him still as he's very lively and wanting to play now!
