My little dude Oliver is the classic example of a "mutt" by definition.
Here he is as a puppy.

If he behaved better would have possibly tried to make him a dog model, as he is pretty damn cute. But he is a mischievous little dude.
What is pretty awesome is his parents are my cousins two dogs.
Here he is pretty recently hanging out with this mom and dad. He is the top right.

His father (middle left top) is half Cavalier King Charles Spaniel and Half Poodle, so he is what is known as a "Cavapoo."
His mother (far bottom right) is a miniature Alaskan Eskimo Dog (apparently once known as the Spitz breed but it was changed because they were a German breed).
His parents were not supposed to be able to breed, but the vet she used "messed up" and said they were both spayed and neutered when they actually were not. Pretty crazy story and my cousin had no idea the mother was pregnant until about 5 days before she gave birth. She is super fluffy so her belly was not obvious.
