Chihuahuas are a smart and intelligent dog breed. Chihuahuas are also know for being fast learners. While Chihuahuas are smart, they are not known as people pleasing dogs. This means you will need to persuade a Chihuahua to perform desired behaviors.
The Chihuahua dog breed ranks 67/100, just ahead of Lhasa Apso and Bullmastiff. The intelligence rating of 67 is considered to be a “Fair Working Intelligence”, meaning Chihuahuas require 40-80 repetitions to learn new commands and obey first command 30% of the time or better.
