Long story short, I had 5 dogs for about 5 years. Molly (oldest and one of the of the smallest)has always been the alpha in our pack. A few months ago we adopted two small female dogs from the spca. Now Mojo (one of the adopted girls - pom x) has decided to try to dominate my one very submissive little dog to the point where she nips at her now. I am wondering how to handle this and correct it. I cannot put them in the dog run together because Mojo will corner Haley and Haley starts to shake. They have never had a "dog fight" and today was the first time Mojo ever nipped at her and refused to listen to me when I told her no. (She has always listened in the past and walked away from Haley at that point).
