Hello everyone, I'm in need of some help and advice as I'm at my wits end. We have a 2 year old male neutuered bulldog. He is outgoing and playful, although has some resource guarding when it comes to toys. We were asked to take in a 4 year old male neutured rescue Bulldog mix that was from an abused home. It all happened rather quickly but we brought Winston home. We tried introducing them in a neutral place, with scents, they go for walks together and do great. But in the house they can't be off leash or in the same room without trying to fight. They got into one major one where Winston latched on to diesels head and neck and we couldn't get him off until we sprayed water on him. There was quite a bit of blood. We just don't know what to do from here, we want to help Winston have a home, but Diesel is our baby and we don't want to see him hurt again.
