Dogs have been bred for desired behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They have the same number of bones (with the exception of the tail), powerful jaws that house around 42 teeth, and well-developed senses of smell, hearing, and sight. Compared to humans, dogs possess a superior sense of smell and hearing, but inferior visual acuity. Dogs perform many roles for humans, such as hunting, herding, pulling loads, protection, companionship, therapy, aiding disabled people, and assisting police and the military.
Communication in dogs includes eye gaze, facial expression, vocalization, body posture (including movements of bodies and limbs), and gustatory communication (scents, pheromones, and taste). They mark their territories by urinating on them, which is more likely when entering a new environment. Over the millennia, dogs have uniquely adapted to human behavior; this adaptation includes being able to understand and communicate with humans. As such, the human–canine bond has been a topic of frequent study, and dogs' influence on human society has given them the sobriquet of "man's best friend". (Full article...)
The Afghan Hound is a hound distinguished by its thick, fine, silky coat, and a tail with a ring curl at the end. The breed originates in the cold mountains of Afghanistan. Its local name is Sag-e Tāzī (Dari: سگ تازی) or Tāžī Spay (Pashto: تاژي سپی). Other names for this breed are Tāzī, Balkh Hound, Baluchi Hound, and Barakzai Hound.
The American Kennel Club (AKC) describes the breed as among the most eye-catching of all. The Afghan Hound is an "aloof and dignified aristocrat of sublime beauty." Despite their regal appearance, the Afghan possesses an "endearing streak of silliness and a profound loyalty." (Full article...)
A Standard Poodle in "working clip" retrieving a mallard. Retrievers were bred primarily to retrieve birds or other prey and return them to the hunter without damage. Although spaniels and some pointing breeds routinely retrieve game, and many retrievers are skilled in finding game, retrievers are distinguished in that non-slip retrieval is their primary function. As a result, retriever breeds are bred for soft mouths and a great willingness to please, learn, and obey. Poodles, though developed as hunting dogs, are most commonly used as companions.
The Egyptian dog Abuwtiyuw, also transcribed as Abutiu (died before 2280 BC), was one of the earliest documented domestic animals whose name is known. He is believed to have been a royal guard dog who lived in the Sixth Dynasty (2345–2181 BC), and received an elaborate ceremonial burial in the Giza Necropolis at the behest of a pharaoh whose name is unknown.
An inscribed stone listing the gifts donated by the pharaoh for Abuwtiyuw's funeral was discovered by Egyptologist George A. Reisner in October 1935. It was apparently part of the spoil material incorporated into the structure of a Sixth Dynasty mastaba (pharaonic-era tomb) after the demolition of the funerary chapel belonging to Abuwtiyuw's owner, where the stone likely had originally been installed. The white limestone tablet measures 54.2 × 28.2 × 23.2 cm (21.3 × 11.1 × 9.1 in). The inscription is composed of ten vertical rows of hieroglyphs, separated by vertical lines. (Full article...)
