Good genes??? One of mine, Sugar, yodels constantly, at everything, usually because she's happy. My older boy, Shadow baroos when I come home, snarks and mouths off at the other dogs all the time, and is very vocal in many different ways. My other girl, Damisi, I have heard her about two to three times in total-she's three. Of the puppies, Frankie (a Tri) is very vocal, and Johnny is very quiet. Johnny will vocalize, but not very often. As for, I think what you are getting at by 'good genes', correct me if I'm wrong, is their attitude, it depends on the line, the dog, (for me) the colour. My tri boy is a trouble maker all by himself. My black girl is 'busy' and very energetic. My older black boy is too smart for his own good, but very lazy and will only get into something if he can figure it out-like opening doors. My tri Girl is usually very good-once in a while she gets into something. My little black puppy boy is simply put-a puppy and will get into things, but is very sweet.
