Differences in temperament between dogs and bitches?
In general the temperament should be similar. You may find that a Maremma male is not affectionate to male humans and associates more easily with women and vice versa. People who have lived with many Maremmas probably feel that one sex is as affectionate as the other. Differences are seen more when Maremmas are working with livestock, then, the male is certainly more aloof.
