Bella is most likely resource guarding. I would start by feeding her by hand and making her do something to get the food. With bones I would take them away altogether for a while until she starts to realize her place. She should not get on the furniture until you give her permission, or your bed. She should sit before she goes out to pee and before she comes in. Repeat that for a week or so to when she seems to respond positively, and then giver her a bone but again, she has to sit to get it.
Yeah I make her sit before I give her food or take her out for walks. I also have her sit as soon as we get back from walks and patiently wait for me to take the leash off. Thank you for all advice I definately am willing to try anything.
