fausto is a male and it depends on how you raise you pup. fausje does mark his territorium outside our boundrys. he never does it within our yard and we have an enormus back yard. he has never peed inside the house! (to mark that is ofcoarse! when he was a puppy he did have his acccidents!) i tought him to pee at specific areas and he does it only where it's allowd.
