Onyx knows which one is our vitamin/meds cabinet in the kitchen. I keep her ear stuff in it too and she knows when it is time for ear treatment. She is such a good girl about it. I feel bad that her ear hasn't cleared up, but she is getting tested for allergies, so maybe we can get this taken care of soon! She also knows, when I grab my cell phone that it is time to go in her crate... even if I don't lock her in she goes automatically. Aren't GSD's the smartest???
