It's possible that now that Kaddie has passed, Twinkle is stepping into the position of Alpha dog - but she doesn't really understand her position and what it means as regards the humans in her "pack".
Other than the necessity to teach her who the Boss *really* is, I'm not sure what to tell you: I've never had a dog that didn't accept the humans as being the true Alpha. I guess there's always the chance there's a medical issue, but I think it's probably more behavioral.
Good luck! |
