Oftentimes, when there’s a runt in the litter, he or she doesn’t make it past the first few days due to medical complications. But sometimes, with enough care and encouragement, they pull through. Even the teeniest of living creatures can thrive and overcome the odds…and Pip the tiny pug from the U.K. is one of those miracle stories.

She’s half her sister’s size and measures in at a mere four inches tall. Pip was born with a cleft lip, and has battled with pneumonia for most of her young life, but her vet says she should be just fine after she makes it past these first hard months.

I hope all the best for this pocket-size pup! It sounds like she’s had quite the tough time, but her vets and human parents are very optimistic about the future. She should probably be nicknamed Powerful Pip!
