So smart! Mocha doesn't trade up but when I was in my office the other day, he looked at me and start hopping and turning. "What do you want?" More hopping and turning. "Show me" and I got up. I've never taught him to "show me", but he ran down the hall, stopped to make sure I was following. Ran into the kitchen, stopped to look back at me. Ran to the fridge and looked up at the top and then back at me. There was his bully horn on top of the fridge. "You want your bully horn?" More hopping and turning. I gave him his bully horn and he went back to my office. So smart!
