A charming dog, the Pug makes a wonderful companion, loving of its owner and gentle with children. This is a very intelligent and intuitive Molosser, usually responsive to obedience training, but sometimes fairly stubborn and undemonstrative. Some specimens are quite feisty and can be unfriendly towards other dogs, but the Pug is generally a relaxed and even-tempered pet. The body is stocky and muscular, with a very short neck and a round, short-muzzled head. The skin is moderately wrinkled and flexible, especially on the face, which has fairly large and expressive eyes. The tail is tightly curled over the dog's back.

The coat is short and smooth, coming in solid colours of fawn, silver, apricot and black. Light-coloured examples have black masks covering the muzzle, eyes and ears. Some specimens even have a black line on the back, extending from the head to the tail. The average height is 10 inches.
