has anybody got any experience with keeping 2 ddb males together?they are both around two years old??

I have 3 ddb 2 bitches 1 male. I know many many breeders of ddb and most of them would not keep two together as they are well know to dislike the same sex, but i also do know a person who has two males and they are inseprable. So before doing so make sure you reserch the breed properly. I would not fancy trying to split up a fight with two sixteen stone dogs ripping and tearing at each other.

I wouod suspect havign two same age would pose the greatest likelihood fo fighting in any dog dominant breed.  It isn't worth the risk, as who suffers if it doesn't work?
