Small Dogs Are Likely Decendents of Middle Eastern Wolves

Scientists at UC Los Angeles have found a genetic connection with tiny dogs and Middle Eastern Wolves.  The study found that the IGF1 gene controls body size and they were able to determine that the diminutive size of dogs was likely created through breeding after the domestication of dogs.  The genetic connection with the Middle Eastern Wolf combined with archaeological evidence makes a good solid argument that maybe that Chihuahua came from the Middle East.

Dr. Melissa Gray one of the leaders of the study spoke with ABC News about the findings: 

"We have had some other studies that have pointed to the Middle East as being involved in either domestication or body size," she said.

"For instance archaeological evidence has found that there are remains of small dogs in this region. So it's one of the first regions that has been identified with small dogs."

Those remains are dated back about 12,000 years.

The study of dog genetics helps us understand the history of domesticated dogs and may actually help breeders and developers of medications in the future.
