Leonberger
At first glance, you might think the Leonberger is a teddy bear because of how fluffy and cute they are. They are muscular and large dogs that have a generous double coat. When you buy a puppy, it would immediately melt your heart, but they grow up to become even more adorable.
Their faces often have a black mask, and their bodies are a mixture of black and different shades of brown. Leonbergers get their name from a city of Germany with the same name. They are pretty intelligent, so they make perfect search-and-rescue dogs.
