£2000 for a cruciate? Crikey, is that what ALL vets are charging now? What a rip off! We had an idiotic 40kg dog who, 2002 I think, needed her cruciate replaced, £236 the bill was. Went back a few months later to have it replaced with one suitable for an elephant (the vet said, as he'd never known such a loon!) A few months later, went back and had the other leg done with elephant ligament, waste of time otherwise. But each op was around the same price.
They are also an independent practice. Even now, they are independent but have had to raise fees, but still cheaper than many.
