Small Dogs Originate in Middle East, Says Gene Study

Small dogs may all originate from the Middle East, according to research from the University of California. A study published in the journal BioMed Central found a gene found in small dogs, IGF1, is closely related to one found in Middle Eastern wolves. Archaeologists have found the remains of small dogs dating back 12,000 years in the region. In Europe, older remains have been uncovered, dating from 31,000 years ago, but these are from larger dogs
