Chihuahua vs Human
Chihuahua is the smallest of all the dog breeds in the world.
It is named after the state of Chihuahua in Mexico and is very popular breed, particularly in America.
These small dogs were first recognized by the American Kennel Club in 1904.
They are also called by people with the name Chiwawas and Chi Dogs.
History and Origins
The History of Chiwawa is very hard to trace, but there is sufficient evidence to prove that it is originating from Pre-Columbian Mexico.
The most common theory is that Chiwawas are descended from the Techichi,
a companion dog favored by the Toltecs and that the modern dog developed through breeding
with miniaturized Chinese dogs brought to the Americas by the Spanish Conquistadors.
Compare with their ancestors, present day Chi Dogs are much smaller. Genetic tests have placed Chiwawas originating in the 1800s.

it is especially important to know what group your dog belongs to in the Kennel Club of your country.

Exercise
Before you learn how to train a Chihuahua, it is important to know that Chihuahua training should come together with exercise.
Chi's body is tiny, but it still needs to exercise.
I suggest exercising with you dog for 45 minutes daily.

barking and other dog behavior problems.
Remember that all dogs are NOT meant to be confined in a location.
Even if you have a big backyard, your dog still needs to go out and explores the outside world.

All dogs shed. Smooth-coated Chi dogs shed more frequently than long-coated.
Long-coated Chi dogs shed seasonally, about twice yearly.
