Serendipity
New Born Pup
I have 2 bonded sisters that are 4 years old. Esther has always been the dominate one. I have got 2 four week girls and introduced them slowly and all seemed fine. Now Esther is bullying her sister and has taken control over the little ones. She has nipped her sister and taken some fur off her. She doesn't like her around the little ones. Any advice would be fantastic. I'm even thinking of getting a separate cage so I can split them up.
