You post is very well written. I am so sorry that you and Kirk are having to go thru this. Perhaps you could phone the breeder and reiterate what you've written here - it's great. The breeder should be notified and in turn should notify the other puppies owners - that would be the responsible thing to do. Kirk sounds like he's in very capable hands and will be getting the very best of care - good for you girl!!! Take care of that sweet boy, I pray that his problems can be fixed and that he can live a happy, pain free life going forward. To help release some of his energy is he having at all the chew toys?
