Those Special Guinness World Records for Dogs

1. The oldest dog breed

The oldest known domesticated dog breed in the world is Saluki, which is believed to have appeared in 329 BC. Saluki was highly revered in ancient Egypt and kept as a royal pet and mummified after its death. Some sculptures have been found in Sumer (it is the south of Iraq now), among which, the dog representative is very similar to Saluki in 7000 BC.


2. The smallest police dog

Midge, a hybrid mixed by a chihuahua and a rat terrier, is 58 cm (23 inches) long and 28 cm (11 inches) high. It works as an official law enforcement working dog (or "police K9") together with its owner, Sheriff Dan McClelland (from the USA), in the Geauga County Sheriff's Office in Chaton, Ohio, USA. Midge passed the certification of drug detection dog in Ohio on November 7th, 2006, which means that it is alert to the existence of marijuana. It can be used for arrest, search and drug control and its actions are recognized by courts and judges.


3. The smallest service dog

The smallest service dog is Cupcake, a female long-haired chihuahua with a height of 15.87 cm (6.25 inches), which is owned by Angela Bain from Morristown, New Jersey, USA.


4. The heaviest dog hairball

The heaviest dog hairball weighs 91.172 kilograms (201 pounds), which was created by a Texas hearing aid dog in Austin, Texas, USA on April 7th, 2012.


5. The longest-lived dog

According to records, the longest age record of dogs is 29 years and 5 months. The record belongs to an Australian cattle dog named Bluey which was raised by Leshall from Rochester, Victoria, Australia. Bluey was born in 1910, and worked in cattle and sheep for nearly 20 years, and passed away on November 14th, 1939. Most dogs have a life span of 8-15 years, but it is rare to record a dog life span which is more than 20 years, which usually falls into the smaller breeds of dogs.

At the bottom of the list is the Afghan hound. The dog at the top of Professor Colon's scale is proved to be particularly smart, it is even able to understand the vocabulary amounting to 250 words, which is equivalent to a two-year-old human child.
