Least Intelligent Dog Breeds; Sorry if Your Dog’s Included

The Chihuahua is a tiny dog paired with a GIANT personality. Known for being “purse dogs”, they are among some of the oldest breeds of the Americas. Their coats come in various amounts of colors, and they can be long or short. They can be fast learners, but their retention for teachings doesn’t last too long, which is why they are number 13 on our list. Chihuahuas are actually one of the most difficult breeds to potty train and become attached to their owners, making meeting new people difficult.
