That is also part of the pecking order routine. But, even though they are brother and sister, when they do become sexually mature, they will mate with each other. Being related doesn't matter to dogs when they are driven by instinct to reproduce. So it would be a good idea to have them spayed and neutered before Shadow goes into heat. And having just Shadow done won't be enough. If Bull isn't neutered he'll still try to mount Shadow and his raging testosterone can start fights that you won't want to get in the middle of when they are older.
