The Chihuahua is the smallest breed in the world. Chihuahuas are small dogs with big personalities. Chihuahuas are extremely loyal and loving and tend to become very attached to one or two of their human family members. Chihuahua's crave love and attention all the time from their humans. Once your Chihuahua has warmed up to you they tend to be very sweet and gentle dogs, although they are great watch dogs because they have a hard time warming up to new people. Chihuahuas are always ecstatic to greet their owners, it doesn’t matter if you have been gone 10 minutes or 5 hours they are always happy you came back home! They also make excellent lap dogs, because they love being near or "on" them as much as possible.
Many people have called the Chihuahua "yappers" or "ankle biters" and if you are a Chihuahua owner then you know why. Chihuahua's are excellent watch dogs; they will let you know as soon as someone pulls into your driveway. This is why socialization is very important with the Chihuahua. If your Chihuahua has been properly socialized at an early age then he will be more outgoing and confident towards certain situations.
Some people tend to think potty training a Chihuahua is more difficult than potty training a lager breed. This is not true; as long as you’re consistent with you puppy then potty training should be easy. Never stray from the house breaking rules and make sure to keep an eye on your puppy as they run through the house. People tend to let small dogs get away with what they want because they are small and this is a big mistake, Chihuahuas need boundaries just like any other dog. If these boundaries are not set at a young age your puppy will develop bad habits.
