8 year old pit mix (Chambana)

8year old female pit/boxer mix needing an amazing home.
She is fixed, great with kids, good with small animals and cats but is starting to be protective around food.
Extremly loving dog but does get anxiety.
She is Obsessed with her stuffed animal toys and will happily carry them around with her.
We have never crate trained her and never had a reason to.
She may do best in a home with not many stairs as she does not do well with them at times.
