Teresa,
What a very informative post !
And if we focus on one thing that Suze said...
"If ANYONE goes near my shoes, except for me......she attacks"
Makes me think there's a little more to this than just Resource Guarding,
and your #5 Item, is probably the best way to go with it.
I'd be very interested to hear how Bella acts, when Suze and one of
her children play with a Toy, just with each other. ie: not including
Bella in the play. (tug/throw/whatever) Then, a comment if
that toy or item, was then included in Bella's Guarding Inventory.
