Jeez – what vets do you use? That would have cost us around £25.
At that point, a very well know chain of vets. Suffice to say we now use a local vet.
I remember the vet clicking a button on his computer and it was charging us by the second (or so it seemed).
Our vet (whom we called last night) was fantastic. The way I felt after trawling through tens of google pages last night I would of happily paid any amount to make sure he was ok.
Just got back from a moorland walk , he seemed right as rain.
Thanks to all for taking the time to respond!
