Chugs have sturdy, well-muscled bodies with their legs being on the short side. They have well developed necks that blend in well with a dog’s shoulders which are nicely muscled.  Chests are broad and deep with a Chug having a nice level back and well developed and well-muscled loins and rumps. Their tails curve over a dog’s back when at rest and when on the move too which is a trait they inherit from the Pug. Feet are small and compact with Chugs having firm paw pads and strong nails.
