Does she growl and get "aggressive" when she has a "treat"?

Seems to me like she may have possession issues.

Please give additional information. Is she given treats in a crate or out and about? Does she seem to growl when someone comes near her in general or when she has a high value item?

Answering these questions will give a better idea what type of advice to give you.

Thanks.
