i've been to vet offices where they have posted signs saying "let us restrain your dog" b/c its their liability if your dog bites YOU! wonder how that works in this situation.
for the record, i generally dont let anyone restrain my pets but me. sure they can have the back half but i always tell them that i'll take "the pointy end."
i'm kinda wondering tho if the owners were 'problem patients' and the dog had a history of being out of control? someone said earlier that some owners think its cute when their little dogs are all bitey and barky... i dont think this is funny either and no matter what the size, you should have control of your dog.
whatever the facts are... very very nutty.
