Looking for advice on behalf of a FB friend. A senior rescue has a torn/damaged cruciate ligament and surgery has been recommended (1800 euros). Money is not an issue but the worry is that the dog is about 12, suffers separation anxiety, and he feels he won't come out of the surgery and the 4 months post-treatment ok. Has anyone managed this holistically or can anybody recommend supplements/treatmens or is surgery the only option?
