Oh, Souraya, I just read this topic. I am as outraged as you are that a shelter manager would even consider putting a puppy down for nipping. This sounds like such a beautiful dog with so much potential. He even sounds like Dog of the Day material! I certainly hope some group will step up to the plate to help you if your friend doesn't adopt.

Thank you for your efforts to help this dog, Souraya, You are indeed the advocate he needs.
