does anyone know what breed of dog that is on the show? is it a mut?

That was my exact reason for coming to this site. I'm not an expert but I do have 4 pugs my self. Rags has a 'Pug' nose, face, and body structure.
But. . . pure bred pugs only come in fawn with black mask and ears or solid black. no brown or brendle according to the American Kennel Club. Looks like maybe a pug mix. Any opther opinions?
