Thanks for your comments. :-)

She has always guarded prized bones, which are not all bones....the really good ones with smoke flavoring for example. She will wait for her food, she will wait for her bone. I could put the best prized bone on the floor in front of her, 3" from her and tell her to wait. She will wait until I say OK. Once she has it, it's hers and she would bite me if I tried to take it.

As far as dry food in her bowl, either of us could walk up and she would at us with a soft happy face. If either of us told her to sit, she would.

Canned food, yet another story. Low level growl if hubby gets anywhere near her while she has canned food. She will wait for him to say OK before beginning to eat. But, once it's hers, she becomes angry if hubby goes near. She doesnt' get angry if I am near, but I touch her while she is eating canned food, she would give a very low level growl. I could sit on the floor next to her and she would do nothing. She would growl loudly at hubby if he got near her canned food.

She's in the FR now with me, blocked from te sofa. She is sitting on the floor beside the obstacle that is preventing her access to the sofa. She's happy, playful, and seems a bit confused, since she has always been allowed on the FR sofa. BTW, she has never been allowed on the chairs, or the LR furniture, and wouldnt' think of getting up on those items. She was with us 3+ years, on the FR sofa daily before ever showing signs of aggression.

She's so sweet, it's hard to imagine this behavior is coming from her.
