Maggie is very insecure and has been doing better but still has her moments. Anyways, her and Indy got into a tiff the other day and I didn't know the best thing to do. The situation was: the dogs had been in the house for a few hours, playing, sleeping, etc. Overall, being very good. Then I sat down and started to eat something. They both of course came over and stared hungrily at me (def. not a new thing!) but I tried to ignore them b/c I wasn't going to give either one anything - I never do. Well, Maggie didn't like Indy being there all the sudden. She started giving him the stinkeye, and showing her teeth a little. Indy was trying to ignore her - you could tell he was purposely not looking at her and was kind of sitting back. He tried to go behind her to get out of the way and she tried to get at him and I distracted her. So, he came around to the other side of the chair where I was sitting. She walked over to him and bit him on the face. He turned around and snapped back at her. I got up immediately to try to "break it up" but didn't know how to react to Maggie. I just pulled her back and she was still showing her teeth to Indy. I tried to ignore her and went in the kitchen to put away the food. They followed me in the kitchen and were cool. I then put them out by giving them each a cookie and they were cool then too. All has been fine since then - they've been playing off and on all day. *wanted to add that the bite wasn't an "I want to tear you to pieces bite" it was like a warning bite. Didn't hurt him a bit - she wasn't trying to - but still unacceptable. I'm wondering if this is a bit of a teenagerlike phase - she's about 1 1/2 now. Indy is technically the boss/dominant one but he is really laid back so he doesn't act like it until he absolutely has to. She gets away with a lot and is very pushy/neurotic. Also, what should you do? I've heard to ignore it, but that sort of went directly against my instinct. That is why I just sort of lightly scolded her. I didn't want to make a big deal of it, but I didn't want her to think it was OK either. This isn't the first time she's gone after him, but I've ignored the previous times b/c he sort of deserved it. He's very annoying and likes to play all the time and doesn't know when to quit. so, when he gets to playing too rough (biting her tail, head, everywhere, wrestling, etc.) and he hurts her or goes to far, she goes after him. He tries to get away from her but if she gets too out of hand being nasty he'll snarl back at her and that ends it. This has only happened maybe 4-5 times. Is this something to be worried about or is it normal sibling rivalry? I've been working with her stranger socializiation and she's been doing good. This at home thing is new.
