Find out the name of the vet.

I like the above suggestion, call the vet yourself and see if this is what he said or if there is some misunderstanding.

Then, based on the second reply, I would not hesitate to contact the state licensing board. At that point, the vet will have told you directly to give a dog chocolate, and you ahve good reason to file a complaint!

I hope youa re able to follow through on this, those poor doggies! what will she be doing "for" them next???
