(Sorry, bandwagon time LOL)
My biggest worry with this whole subject is those owners who (insured or not) think their vets are God and agree to every last treatment offered.
I took a 13.5 year old dog in for a general check-up a couple of years ago. The vet told me she had some muscle weakness and wanted to send her for an MRI.
No shit, Sherlock - a 13.5 year old dog has some muscle degradation (although still happily walking a few miles a day). What did they think they were going to be able to fix if they found it at that age, I wonder?
Now, I have no issue saying no, I won't be doing that. (I am sure I probably have some 'awkward mare' marker on my customer file ...) Unfortunately, a lot of owners think their vets are always operating in the animal's interests and will agree to everything, whether they are insured or not. It really is not always the case, sadly.
Unfortunately round here, most vets are the same - and all are operating with the dreaded VetsNow as their out of hours cover too, with the only exception being just that bit too far away for comfort in emergencies.
We do have a shear-off independent vets recently opened up locally, and I will give that a go I think, although (touch wood) thankfully I don't go very often so haven't signed up yet.
