That is totally wonderful! That sweet little dog probably never knew he had a problem, but now he can be a little more like the other doggies he sees. Just have to love it! What a clever, and simple looking invention!
Amazing story, what a loyal, sad dog to gather the belongings and sleep with them. And an incredible job of detective work to find the family. Thanks for sharing this touching tale.
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.
