Intellectually, dogs are more highly developed than any other brute animal. Many forms act with a rational deliberation and follow carefully thought-out plans. The senses are wonderfully developed. The sense of smell is marvelous in many forms, while strength of eyesight distinguishes others. Of the three groups mentioned, the wolf without question was the ancestor of the domestic dog. In the German mythology, he was consecrated to the god Woden, but when Christianity reconstructed old beliefs, Woden was metamorphosed into "The Wild Hunter," and the wolves became his attending dogs, which finally were evolved into the ghost-like wolves of nursery and fable. The wolf has all the attributes of the dog except the nobility which necessarily comes from education. The tail always droops, never curling upwards as in the domestic dogs, and even when tamed they rarely wag the tail. Among the wolves may be mentioned the jackals of Asia, which are said to have entered largely into the breeds of oriental dogs. These were known to the ancients as "gold wolves," and are said to be the foxes whose tails Samson set on fire in order to burn the fields and vineyards of the Philistines. The Indian wild dog, or "Kolsun" is claimed by many to be the progenitor of all domesticated dogs. He closely resembles a greyhound, and is found all over the Himalaya and East India country. He exhibits many traits characteristic of our hunting dogs. Prominent among several distinctive and familiar breeds of dogs is the Greyhound, which while graceful and universally popular as a pet, and a sporting dog, is unfaithful and unsympathetic. The great lung capacity gives the animal unusual endurance, but while possessed of keen sight and hearing, the sense of smell is very deficient. The Mastiffs constitute another group embracing many of the familiar forms. Among these are the Danish dog, the German Mastiffs, the Bulldog and the Pug. With the exception of the Pug, which is justly called a caricature of a dog, the group is remarkable for fidelity, courage, determination and strength. Great Britain is the home of the Hounds which, because of their intelligence and docility, are considered to be in the first rank of domestic dogs. All the varieties of this group are born hunters, being strong, swift and possessed of unusually keen senses, especially that of smell. Among these are the Pointers, the German Bloodhounds, the Staghounds, the Beagles, and the Foxhound. This last is justly considered the greatest of hunting dogs, possessing the speed of the greyhound, the courage of the bulldog, the delicate scent of the bloodhound and the sagacity of the poodle, he is well equipped for his duties in field and forest.
