This is so sad, tell your SIL and her family that our hearts go out to her. Chopper is just what the doctor ordered for the weekend I would say. Our boxer mix had three fractures in her neck that we didn't know about right before we had to euthanize her for cancer, I assume that her bones were just weak and just to lift her head caused her neck to fracture. That is a sad thing for your SIL's baby. Godspeed Kelsie
