spud knuckle

A dog that is 15 pounds, male and a cross between a Chihuahua and a Beagle. A nickname for a spud knuckle is 'spuds'. To be a spud knuckle the dog must qualify all standards. Spud Knuckles often have a 'Wrinkly' or 'Crinkly' face.

I was walking my spud knuckle today. I threw a stick and little spuds brought it back like a good doggy.
