Some Facts on Dogs You May Not Know
While researching for articles on this website, I often come upon little known pieces of information about dogs. Some of these facts, while great to know, do not fit neatly into the structure of this site. Therefore, I created this page, to share with you some of these interesting tidbits of information, and perhaps peak your curiosity to get more information. If enough desire for any of the below facts is shown, I will be glad to expand on them in a different article.
Oldest evidence of a domesticated dog, 33,000 years!
A dog skull was found in a siberian mountain cave. Radiocarbon dating at the University of Arizona's Accelerator Mass Spectrometry Lab determined the age of that skull was 33,000 years. An additional piece of dog information and facts: Equally old remains of a dog was found in Belgium, meaning that domestication of dogs appears to have been occuring in more than one place at the same time, challenging the thought that all modern dogs shared the same ancestor from one domestication event.
Smallest to biggest dog
The tallest dog ever recorded weighed 245 pounds, and measured 7 feet, 3 inches when standing on his hind feet. This was Great Dane named Giant George, once the runt of the litter. Sadly, Giant George passed away on October 17th, 2013, three years after being recognized by Guinness as the tallest dog on Earth.
In contrast, a Yorkshire Terrier named Sylvia takes the honors for smallest dog ever, measuring 3.75 inches nose to tail, 2.8 inches tall, and weighing 4 ounces. Sylvia died extremely early, less than 2 years old.
A Dogs Intelligence and a Two Year Old Child.
According to a 2009 study in British Columbia, the average dog can learn 165 words and signals, while the most intelligent of them can learn 200 words and signals. This study also determined dogs are able to count, as well as intentionally deceive other dogs and humans in order to get a treat. According to several behavioral measures, the dog's mental abilities equate to a human child between 2 and 2.5 years old.
This study also concluded the smartest of dogs was the Border Collie, followed by the Poodle and the German Shepherd Dog. The least intelligent? The Afghan Hound takes that dubious honor, followed by the Basenji and the Bulldog.
Dogs May Not Taste Good, but They Sure Can Smell!
A dog typically has 1700 taste buds, compared with 9000 in humans. Due to this deficit, dogs typically do not enjoy their foods based on their taste, but rather by the smell. And in smell they excel! While humans have around 5 million smell-detecting cells, the dog has 220 million. The dogs ability to interpret those smells is about 4 times more than humans also. This ability has made the dog a new potential job... smelling out diseases in humans, such as cancer and low blood sugar.
I Hear You!
Continuing with the senses, a dog can hear sounds in a significantly larger band than humans, and for a greater distance. While the human range of hearing is from 20 Hz to 20,000 Hz (20 KHz), the dogs range is from 40 Hz to 40,000 Hz (40KHz) and some say up to 60,000 Hz. Dogs also have the ability to move their ears independently, so can locate the source of the noise quickly, allowing it then to use both ears to capture the maximum sound waves.
