They can reach a height of 6-9 inches (12.7–20.3 cm) and a weight of 2–6 pounds (0.9–2.7 kg). Chihuahuas can have a long or short coat, and come in many different colors. These are black, white, beige, brown, and dark brown. They only need grooming once a week if short coat or it may be twice if you have a long coat. Chihuahuas can have upto six puppies because of their small bodies.
The Chihuahua's start goes back to Mexico as the descendants of the Techichi, a long haired and silent dog. The Techichi was liked by the Toltec people, one of the indigenous (original) people of Mexico. Chihuahuas are believed to have been made by breeding the Techichi and Chinese Crested Dogs (a type of small hairless dog) to form today's Chihuahuas.
Another possible start for Chihuahuas was the breeding of Techichis with Spanish terriers, which were well liked at the time and were known for their small body and black and tan colors. Mating with another type of dog increased the loudness of the Techichi's bark while making it smaller.
