I am so sorry that you lost your baby. I know it must be devastating but don't blame yourself. You didn't know. We all make mistakes. That's what makes us human. You might want to post something under Boxer Ring so others will learn from your mistake and possibly save another life in the process. I feel terrible guilt because my Kianna bolted out the door when she was a pup and was hit by a car, broke two vertebrate. I thank God that she survived and is okay but sometimes she is skittish and fearful because of it and I feel responsible. We just have to be able to forgive ourselves and move on. God bless you.
