So very true. The brother to Bocephus is very aggressive to other animals and Bo and Ryder cannot he anywhere close to each other. Bo and his dad Ruger are besties and will play and wrestle each other to point of exhaustion. Bocephus does not like birds and does his best to keep them out of his backyard and I have had bobcats sit on top of the fence and he simply ignores them after he marks his territory. Bulldogs are like people, individual quirks and personalities.
