Here is a 7 lb Chihuahua playing with Bud. She slaps him in the face when they are playing and he just takes it. Chihuahuas think they are big dogs. Here she is waiting for him to come back to chase him.
Chihuahua's country of origin is Mexico. Their date origin is puzzling but it is estimated they have been around since the 5th century AD. They were first recognized as a breed in 1884. They are companion dogs with an energetic, alert, loyal, and sometimes feisty temperament. With proper training and nutrition, you can have a happy and calm Chihuahua. They need to be exercised just like big dogs. They do not need to be carried around all the time. They are smart and be trained just as much as big dogs. In a puppy class I took Bud to, my dog trainer said there was a Chihuahua in her class and that is was unusual to see a Chihuahua in training. It makes me sad when people do not train Chihuahuas and just carry them around in their purses all the time. Please give them as much attention as you would a big dog.
