Ok the girls are CONSTANTLY (and I mean CONSTANTLY) fighting!!! Anytime they are out of their crates they are running around bite and attacking each other. I know Hannah is just trying to play because she'll give her a little nip run away and grab a toy and wait for Lily to come and play. Lily, on the other hand, is constantly jumping and biting and growling at Hannah. I think Lily is trying to become the dominant dog in this family. Hannah will chill her out if she gets to rough and will bite and won't let go until she yelps but Lily will just keep coming right back. Lily is always showing her teeth while they are playing. If I say "knock it off" Hannah immediately covers her teeth back up and relaxs where Lily's still showing her teeth at Hannah and will jump on her two seconds later. I'm very worried about them. I have tried giving Lily time outs but she doesn't care and the second she is out she is jumping and attacking Hannah agian. She isn't drawing blood but I'm afraid that is what she is attempting to do. Is this just me being paranoid about them playing? I have never really seen these two actually get along without biting and chasing each other unless they are dog tired (excuse the pun). I'm just worried maybe Lily doesn't like Hannah. She always wants to be with her, they have to have their crates by each other and when I let Lily outside she immediately runs and sits by Hannah's so I can let Hannah out for them to play. Hannah goes outside first and gets food and treats and I TRY to give her attention first as well. Any suggestions?
