Dog Facts

  • Domestication of the dog began around 15,000 years ago and during this process, humans selected for particularly desirable traits such as coat colour and leg length.
  • This selection process has resulted in over 400 different breeds of dog, 209 are recognised by the UK Kennel Club.
  • Dogs have an incredibly well-developed sense of smell, far superior to humans.

  • Dogs can see better than humans in dark and dim light.
  • Communication is very important in helping dogs form and maintain social groups.
  • To transmit scent information, dogs use urine, faeces and secretions from special scent glands.
  • Many dogs can use their body, face, tail, ears and limbs to communicate with other dogs.
  • The fastest recorded speed for a greyhound is 42 miles per hour, similar to that of a mounted racehorse, which can reach speeds of around 43 miles per hour.
