This little black and tan puppy is also known as the smallest puppy in the world and one of the cutest puppies I’ve ever seen. This puppy might even be in the Guinness Book of World Records if he doesn’t grow any more than he is right now. He is four inches and three ounces. He can even fit into a tea cup. He is the smallest of his three other siblings that are almost three times his size!! This puppy is so small, I don’t think it's going to grow anymore. They should just put it in the Guinness Book of World Records. It is three ounces. Not even a baby is that big. If a baby is that big it would be dead. I’m surprised that this puppy is not in the hospital. http://www.dogonews.com/2009/04/06/this-cutie-may-be-the-world-s-smallest-dog
