Millions of people on the planet believe in psychic phenomena - this doesn't irk me. But when your dog is lame you bring him/her to the vet, not to a psychic. In any case, shouldn't this psychic have predicted this dog's injury and prevented it?
I feel that imparting your own beliefs onto your dog is irresponsible, and potentially dangerous. A diagnosis can be missed if you're seeking help from people who have no business giving out medical/veterinary information. Trust your vet. This is exactly what we were trained for: not to be pill-pushers but to try to achieve diagnoses and institute appropriate treatments. And who knows? maybe the surgeon would have recommended acupuncture....
If your child were suddenly limping, would you take him/her to the ER or to a psychic?
Puh-lease people, enough.

At least she knows what he wants.
