Rhia is definitely intelligent.
She will take my socks from me when I take them off after work and places them in front of my closet, in which I keep my hamper! She also knows the sound of the bag of cheese in the fridge compared to other packaging. It's the only one she will come for. She also knows who "meemaw and pawpaw" (my parents) are. I'll tell her we're going to "meemaw's house!" and she will freak out and get on the couch, ready to have me put her harness on her to go!
