We got this can to keep my Labrador puppy out of the trash, and sure enough, there's no way he can open this lid with his nose.  But it's also just a great design and good quality. The way the trash bag fits snugly around the inside compartment means that garbage stays in the bag, not all over the inside of the can, so much less smelly and nasty.  I wasn't sure about spending this much on a trash can, but worth every penny!
