Something that many toy-breed owners neglect is to sign up for a puppy or beginner obedience class. It is a common misconception that little dogs are perfect by nature and that they don't need training or socialization. Here's a news flash: Nothing could be further from the truth.

The Chihuahua is a dog. As such, the Chi will display natural dog behaviors, such as jumping up, barking, chewing, snapping, or biting. The Chihuahua also displays many terrier-like qualities, including what some affectionately call “selective hearing.” (“If I don't make eye contact with him, I can pretend I didn't hear him call me.”) The Chihuahua doesn't need to become an obedience champion (but wouldn't that be cool?), but she does need to learn basic house manners, and you need to learn how to teach her these manners.

Signing up for a training class may not be necessarily easy. Some times of year tend to be busier than others. For instance, the months of March and April are often packed with unruly Christmas puppies. You want to begin your Chi's training as soon as your veterinarian feels it is safe to expose your vaccinated puppy or adult dog to potentially infectious dogs. If you haven't already gotten a spot in a class, you may have to wait weeks or even months for an opening.

Investigate the different trainers and training facilities that are available in your community, and get signed up in advance. It may take a while to find someone you want to work with, who is within a drivable distance, and who has an opening in an upcoming class. Don't dally.
