Okay, I am hoping that tonight's eposide is a little more in depth than last weeks season premiere. I kind of felt like there weren't too many answers to questions that were left last season. Anyone else feel that way?
I believe the sharper front teeth are the pinchers and rippers, the back molars are for really chewing, with big surfaces for grinding. We humans don't usually chew with our front teeth either, we bite and move the food to the rear of our mouths for chewing.
Something similar was at a big dog show in my area a few years ago. The one I ran my dog through had an A-frame and tunnels as well as the jumps and tire. It was a blast!
