That’s really awful. I found some info about veterinarian malpractice. but I don’t know if this will help. It sounds like you would need to prove injury to you over the issue. I’m sure a lawyer could help to determine if you can sue for negligence based on emotional damage.

For a plaintiff (animal owner) to recover damages for injury to an animal, in an action based on malpractice, all the following elements must be proven by the plaintiff (FN 14):
(1) The defendant was under a duty of care toward the animal in question. The veterinarian had accepted the responsibility to treat the animal.
(2) The actions or nonactions of the veterinarian did not conform to the professional standard of conduct (C & D infra.).
(3) The failure to conform to the professional standard was the proximate cause of the injury or harm at issue (E infra).
(4) The injury or harm resulted in damages to the plaintiff (not just the animal in question.
