Keep it, kill it, or bring it back

I just had a conversation about this last night with my wife. She was upset with me about culling a dog i had raised from a pup. My wife kept insisting I should have given the dog to a young hunter or to someone as a pet. I was trying to explain to her that the guy i got the pup from doesn't like just anyone having his dogs. The right thing to do in my eyes is to check with who ever gave you the dog first and foremost before doing anything with the dog. It burns me up having to get someones blessing to do something with a dog that I have fed for a few years. But i exspect the same respect from someone i might give a pup to. Just my thoughts on the subject.
