The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it was domesticated from an extinct population of wolves during the Late Pleistocene, over 14,000 years ago by hunter-gatherers, prior to the development of agriculture. The dog was the first species to be domesticated by humans. Experts estimate that due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
The Taiwan Dog (Chinese: 台灣犬) is a breed of small or medium dog indigenous to Taiwan. These dogs are also known as the Formosan Mountain Dog. They are well-adapted to the uneven and thickly forested terrain of Taiwan, having become a semi-wild breed prior to the arrival of several colonial reigns and foreign powers. Notwithstanding these adaptations, Formosans retained the potential to be trained and are now used as hunting dogs, guard dogs, stunt dogs, rescue dogs, or simply as companions. Formosans are classified into one medium type and two small types. (Full article...)
A Border Collie herding sheep. Border Collies can take direction by voice and whistle at long distances when herding. Their great energy and herding instinct are still used to herd all kinds of animals, from the traditional sheep and cattle, free range poultry, and pigs, to deer and ostriches. They are also used to remove unwanted wild birds from airport runways, golf courses, and other public and private areas.

Kennel cough (also "canine infectious respiratory disease" (CIRD), "canine infectious respiratory disease complex" (CIRDC) or "canine infectious tracheobronchitis" (CIT)) is an upper respiratory infection affecting dogs. There are multiple causative agents, the most common being the bacterium Bordetella bronchiseptica (found in 78.7% of cases in Southern Germany), followed by canine parainfluenza virus (CPIV; 37.7% of cases), and to a lesser extent canine coronavirus (9.8% of cases). It is highly contagious; however, adult dogs may display immunity to reinfection even under constant exposure. Kennel cough is so named because the infection can spread quickly among dogs in the close quarters of a kennel or animal shelter.
Viral and bacterial causes of canine cough are spread through airborne droplets produced by sneezing and coughing. These agents also spread through contact with contaminated surfaces. Symptoms begin after a several-day incubation period post-exposure, and in most cases will clear up on their own. However, in young puppies or immunocompromised animals, mixed or secondary infections can progress to lower respiratory infections such as pneumonia. (Full article...)
