My springer spaniel, Trixie!! She is the best dog/friend I ever had (neck and neck with my husband). I've had her since she was 6 months old, now she is 10 years. Talk about a wagging tail, hers is like a motor ready to take off. Very smart as well. I only have to show her once how to do something and she's got it. My husband likes to take off his socks and put them on the living room floor, drove me crazy for years. I taught Trixie to pick up the socks and put them in the washer (I refused to, lol). Then I had to have gamma radiation, I couldn't put my head down afterwards for awhile, so I taught her to take off my socks, put them in the washer, and then bring me my slippers.
I always have to be where she can see, whether inside or out, otherwise she will come looking for me like a crazy dog. I'll find a way to put a picture of her on here.
