I have an African, she's 9 1/2 months old. Got her at 3 days old. Highly socialized her every day. Lots of hands on and spend time with her every day. This helped ALOT, especially with her breed. We selected African cause they're very loud and known to be guard dogs which is what we needed. I researched and read they can be social if appropriate time is spent with them so that's what she did and she's a doll. She's skeptical of people she doesn't know which is what we wanted but can be bribed if you know what to give her, then she's your friend. When strange cars or UPS comes she goes toward the front yard and stands tall and intimidating looking. As far as a noisy alarm system, so far, she actually gets quiet, so she doesn't draw attention to herself when she's concerned about something. The Runner and Welsh Harlequin we got with her are braver up to this point. She's noisy at times when people come to the house, or the drakes are getting too rowdy but hasn't alarmed about a potential predator, she gets silent (as she did when a racoon came onto the property). She was months younger then though and hasn't had another opportunity to react toward a wild animal yet. She's even scared of our guinea pig so.... She's definitely not that Doberman pincher of geese as the breed is known to be. Could be of how well she's been socialized I dunno. She's also a single goose with a bunch of ducks so not sure if that makes a difference and she's possibly absorbing some of their characteristics when it comes to certain things.
