He has a lot of interesting quirks.
This morning I had him loose while I was getting ready for work. He walked by Zorro's crate (with Zorro in it) and of course Zorro barked at him (how dare another dog go near his crate). Pollux stopped and gave him a look.
Then, Pollux pulled part of the blanket that was on top of Zorro's crate so that it blocked the front of the crate.
Sometimes he's too smart.
