I am glad that Keva seems basically alright.

That poor German short hair, being kick by its owners? I mean, I understand it was at the point that they HAD to do that, from the sounds of it. But this is not going to help in their relationship with their dog.

I hope they can find some trianing program for the dog, and are willing to put in the time to work with it.

Sad for the boxer as well, to live with a dog which attacks it.

I suppose you don't always know until you get the dog home. But once you DO know, you need to address the issue!
