We just learned about the Siberian Husky.
Another type of dog is the Shar Pei.
The Shar Pei has very loose skin all over it's body as a puppy. As it grows older, the skin stretches out a little, but it is still very loose especially on the their face.
These dogs were used as farming, hunting and fighting dogs, because if whatever animal they were fighting got a hold on their skin they could stretch their skin out to turn around and bite them back.
