Affenhuahua #1 Average weight: 3 lbs Maximum weight: 6 lbs Coming in at three pounds on average, the Affenhuahua is the smallest recognized dog breed in the world. A cross between Affenpinscher and Chihuahua purebreds, Affenhuahuas are friendly and social, but are not known for being good with kids.
Chihuahua Average weight: 4 lbs Maximum weight: 6 lbs Chihuahuas are tied for spot number two, with an average weight of four pounds. They’re an extremely intelligent breed, and with a life expectancy between 14 and 20 years, one of the longest-living as well.
Average weight: 6 lbs Maximum weight: 8 lbs The Chin-wa is a mix between the purebred Chihuahua and Japanese Chin. They’re not known to be good around children, but they’re still loving, playful, and would be a great choice for anyone looking for a small pup that doesn’t shed much.
Average weight: 6 lbs Maximum weight: 9 lbs Like the Yorkillon, Cheeks dogs are a cross between two breeds—the Chihuahua and Pekingese. They have both long and short coats, so if you don’t like grooming but love the breed, you can always opt for a Cheeks with shorter fur.
