SOCIAL LIFE OF ANIMALS 



Dog. — The dog is supposed to be the oldest domesticated animal. 

 From the savage Australian Bushman to the cultivated people of the 

 world's greatest cities, we find that the dog is a companion and 

 servant. He seems happiest in caring for the possessions and person 

 of his master and will follow and protect the drunken sot or the filthy- 

 beggar. 



There are about 200 breeds of dogs, 50 breeds being sportmg 

 dogs. Theories of the origin of the dog place his ancestry as from 

 the wolf or a jackal-wolf hybrid, although there are seven wild 

 species which may have been contributory. The reputed ancestors 

 include the jackal of Western Asia, the jackal-wolf of northeast 

 Africa, the landga of India, the walgie of Thibet, and the coyote 

 and gray wolf, both of America. Fossils of the American dog are 

 found in the Southern Appalachian Mountains near the Cumberland 

 Gap in Eastern Tennessee.
