Contract law does not provide for punishment, except in cases of fraud. If you have evidence that the buyer was abusing the animal, your recourse is to contact law enforcement (police/sheriff) and report the abuse. If you accepted the return of the animal, then the buyer is entitled to her payment. Stopping payment may constitute a fraud on your part, leaving you open to punitive damages,in addition to the original payment amount.
I understand that you may feel justified in your actions -- however, the court may find that the law compels a different outcome. So, you may want to consider returning the buyer's money.
Hope this helps.

This woman purchased my puppy through the breeder who also believed her that she was a "doberman" person and knew what she was doing? Is that fraud?
In other words, you want to counterclaim that the buyer defrauded you by claiming to be other than she actually was, and that had she not, you would never have sold the animal to her.
Okay, you could do that. This still doesn't give you the right to stop payment on the check, but if you could show that the animal is permanently injured, then you could get damages for that.
