In case you needed further proof that dogs are human souls in adorable furry packages, look no further than Lynn Terry's photo series of dogs in a photo booth. Apparently humans aren't the only mammals capable of posing for an adorable series of quick shoots that make your heart melt. 

Look at that range of emotion! 

Hopefully you are smiling a little wider after that beautiful display of genuine puppy love.
