I'm so sorry to hear this. I'm not going to judge your decision, and hope Chad recovers. My brother adores dogs and has owned at least 5 large breeds, but I swear everytime he walks past a small dog they bite him. thankfully no one ever had their dog put down because of it. Maybe Mr. Biggles just needs to be in a male-free home. The dogs that have bitten my brother all had issues with men.
