When photographer Stephanie McCombie saw her two German shorthaired pointers eating peanut butter, she couldn't resist grabbing her camera and taking a few shots.

"I burst out laughing at the faces they were making," she said on Instagram’s blog.

McCombie posted Travis and Gus’ peanut butter photos on Instagram with the hashtag #peanutbutterseries.

Her rescue dogs’ hilarious photos inspired hundreds of other dog lovers to break out the peanut butter and start snapping pictures.

Want to capture your own dog's peanut butter face? McCombie has a little advice.

"Don’t be afraid of a little mess, and have lots of peanut butter on hand. Shooting in a space with lots of light works best — must avoid blurry tongues!"

Check out some of the adorably messy photos from #thepeanutbutterseries below.
