Please dont be upset. This attitude of some people I have personally experienced. And its really sad that a human can treat an animal in such a way.

I have seen here posts and topics about QAWS. I have no idea if they can help but would suggest you approach them and find out. And since it is his dog I doubt if any outsiders can interfere but it is certainly worth a try.

I do hope for the sake of the animal someone can help it.
