I think it's safe to say he killed the dog.

We also have a reason for WHY he was so attached to that dog. It's an animal that is 100% loyal, doing everything it's told. Ward is the dog.
Weird, i always was under the impression he did not shoot the dog. And that it was the last time he actually made a decision on his own.
