I once made a couple hundred tiny sample paw butters to give away at a local event my boss had a booth at. They were a hoot! You can get cheap tins bulk for a decent price on Amazon, plus any other ingredients there too (not an ad, just an addict). 

Dogs are renowned for their exceptional olfactory abilities. With around 300 million scent receptors in their noses, compared to a mere 5 million in humans, their sense of smell is truly a superpower. This extraordinary talent allows them to detect various scents, identify emotions, and even sense medical conditions!
