People love dogs and they love peanut butter.

So why not combine the two?

That's what photographer Greg Murray did.

Murray said he decided to create a photo series out of boredom last winter.

The result was "Peanut Butter Dogs," a book featuring more than a hundred photos of dogs enjoying peanut butter.

The second phase of Murray's project is a calendar featuring rescue dogs eating peanut butter.
