If you get him cut, do you think it would defuse the situation?
Getting a new dog in the house often disrupts the order of things for dogs. They're going to scrap. That said some lines of German dogs have been bred to not back away from a fight or scratch. Great if you need it, terrible if you don't want it.You're probably making the right choice.
