Puppy classes are a must. While these dogs are tiny to the point that their accidents and bad behavior is less impactful as say, a much larger canine, they can still be difficult to train.

  These little dogs love to love, but also require the same amount of attention in return. They’re incredibly keen to their surroundings, which make them fantastic watch dogs, but, they are known to bark a lot. 

First and foremost—especially when your puppy first enters your home—early socialization is key. Introduce your Chihuahua to different environments, strangers, and other dogs. The more you accustom your puppy to foreign environments, people, and dogs, the likelihood of him being more confident and sociable increases immensely
