My dog does laps too. She has always had that mentality. I think it is a corgi thing, like they think in circles. She loves our house for that reason because all the rooms open to eachother and she can do laps around the house.
Morgan is a corgi mutt, so he does not hurd the house, but he is just as nuts.
First I need some $$ for fencing for everyone. But funny thing -- I took Bertie to a herding fun day to see if he had "it" -- but when the handler took him into the pen with the sheep, he's such a momma's boy, he wanted to get out and be with me. I had to go in the pen and chase the sheep to demo for him! I figured he was laughing and pointing out to the other dogs just how low he can make me go. But once we weren't separated, he had a blast driving them around and around the pen.
I think your video is hysterical -- and believe me, I'm sure the ferrets can take care of themselves (and they could get away from the pup if they really really wanted to!). Your puppy is a cutie pie -- now my guys are jealous and want their own pets, too! My neighbors have goats, and I keep offering to get them one to herd around the yard (in the hopes it would eat up all the poison ivy), but we'll see...
