Two very good dogs teach you chemistry

Paige the border collie can load the washing machine, pick up trash, and make toaster waffles (although you probably don't want to eat them afterwards).

And, with the help of her colleague Dexter — and their owner/trainer, who is also a chemist — Paige can even teach chemistry.

Here, Paige and Dexter serve as models for a discussion about chemical bonds — the forces that attract one atom to another and form the basis of all the chemicals that make up our world.
