We have an English Bulldog, a Boston Terrier, and a Shar-Pei. We are responsible, experienced dog owners, have fostered many pups, and have never had a problem having new dogs in our home. Last week, we brought home an 8 week old Old English Bulldog. Today the dogs were outside with my husband and son. The English and puppy were laying together, her between his paws. She got up and started walking. The English hovered over her, then he put his mouth on her neck. She yelped and went limp. We drove straight to the ER vet while I performed CPR on the pup the entire 8 minute ride. My husband called ahead. She had fluid in her body and was showing no signs of life. The vet believes he snapped her neck when he bit her. The English has been in our family since he was 8 weeks old. He has recently attacked cats in our home, the behavior is random. In the past, he has attacked our old Shar-Pei, but again rare and random. He’s been with all of our foster pups without any issue. We can’t have a puppy with him now. But can we trust him at all? Do we re-home him? Put him down? Forgive and move on? We don’t understand why it happened now or where to go from here.
