He is close to be one of the most intelligent dogs who have come into our home. We got one of those flip top crash cans (where you step on a lever on the bottom and it opens). He's actually learned that if he steps on that lever the top opens up to reveal all this garbagy goodness treasure inside!
He and Luna are both smart enough to get into a lot of trouble and nether care about getting in trouble.
At least Zorro and Kire care if they get in trouble.
