Yes, Chihuahuas are hard to train. Although they’re small and cute, they’re also very stubborn. They often display ‘small dog syndrome’ acting as if they’re bigger, scarier, and more important than those around them. Also, as they’re highly strung and often pampered, they typically respond badly if things don’t go their way.
While Chihuahua fans adore their tantrums and entitled behavior, training is a challenge, even for the basics such as potty training.
While it is possible to train a Chihuahua, expect it to be a battle of wills. You’ll need to be ready to invest a lot of time and patience and have lots of positive reinforcement and treats.
