We start off the list with a dog that may be so cute, it's ugly, or so ugly it's cute. The pug, hailing from China, is described often times as "Multum in parvo", or "much in little". Typically this breed grows to heights of 10 to 12 inches or 25 to 30 centimeters, and usually weigh between 14 to 20 pounds or 6 to 9 kilograms. The pug has a short, compact and barrel chested body, with a round head and a flat, dark, snout. Said to be strong willed and rarely aggressive, this breed is suitable for all household environments, as the breed is typically fond of having children around.
