Every dog is different. If the mother didn't get as much nutrition as she should have when she was pregnant, or if there was a large litter and your pup didn't get as much milk, that could factor in her small stature. But if your vet is not worried, I wouldn't worry. Feed her a high quality grain-free puppy food and make sure you take lots of picture's, she'll grow up fast!
