Okay, my little chi Petey has always had a problem with vocalization. He was a single pup, and he was given to us at 6 weeks - so he missed those crucial 2 weeks with his mother, so he's never had normal vocalization.
Now, when we added Winnie and Prince - who were young, but had the benefit of being 2 of 3 pups with a pretty good mom - Petey kind of got more of a hang of pack behavior.
But, his vocalization is still bizarre. He doesn't bark at people - but he will bark and howl when he's playing with Winnie. For example, if they're playing tug-of-war and she gets the frisbee from him, he'll stand there and bark/howl at her while she runs off with it. Needless to say, it can be a bit annoying, but I'm not sure if I should or how I could curb the behavior.
Winnie, on the other hand, (Prince has since left us to live with my cousin), vocalizes more like I've experienced with other dogs - she barks at strangers, at kids on bikes and at passing cars (and we're working on the latter two - and she's responding really well to Cesar Milan's techniques).
Any suggestions? Should I do anything about Petey? Is there anything I can even do?
