Golfer... your facts are fairly accurate. However, dogs are not a seperate species from wolves. The way to determine a seperate species if whether individuals of each can breed and create viable offspring (offspring that is not sterile).

Wolves and dogs can be bred together and their offspring is viable.

"After having slept together for 14,000 years, wolves and dogs are now joined together in scientific matrimony. Quietly, without fanfare in September 1993, wolves and dogs were recognized as the same species. Per the American Society of Mammalogists' Mammal Species of the World, adhering to the Code of the International Commission on Zoological Nomenclature, Canis lupus is the official species of both dogs and wolves. If you have a 'dog', your dog's classification is Canis lupus familiaris, where familiaris is the subspecies of wolf. If you have a 'wolf', your wolf's classification is Canis lupus X, where X is the subspecies of wolf. If you have a 'wolfdog', your wolfdog's classification is Canis lupus familiaris, according to United States Department of Agriculture, Animal and Plant Health Inspection Service, R.L. Rissler, February 21, 1986."
