@Alex Always suggest that it is a male/female pair... of course it would depend on each disposition... but rule of thumb is male/female...so I would think that you might be better with one of each sex, that said, your breeder for the dobie can help you with that especially since Chance is older (way older... LOL) now and yes, always suggest separate feeding... I have always used crates to feed them in... But disagree that temperament doesn't matter in the beginning, but it can... so make sure that your pup has a good temperament and from a responsible breeder.
