My Bella, is similiar. She's very Alpha and she does go after Newman and Noel. Never Tia though. Tia is very small and as cranky as Bella is she is also very nurturing and protective of anything smaller then she is. I'm not really sure why they do this. We've had Bella since the age of five weeks and she's always been loved, well cared for and raised to be a polite well mannered pup and she's great with people. She doesn't hurt Newman or Bella but she will "Attack" them. I've noticed it occures more at night when she's tired or cranky. I'm honestly not sure what to tell you except that I constantly correct her and she doesn't do it all the time. It goes in spurts. Based on my own experience I think that it's just their temperment. She just may be an Alpha and letting your male know it. Does she actually hurt him or does she just make a lot of noise? Bella never bites but it sure looks like she's attacking. Of course I break it up immediately. I hope it works out for you and your babies. Elaine |
