Interesting about dogs

  • Dogs are statistically the second most popular pets in Germany after cats
  • All dog breeds are descended from the wolf. Humans began taming the wild wolves (domestication) about 80,000 years ago.
  • Although dogs can recognize colors (especially blue and green), they are blind to red.
  • With a total of 78 chromosomes, the dog has almost twice as many chromosomes as humans (46).
  • The sense of smell in dogs is by far the most pronounced sense. With their sensitive nose dogs can even smell through locked suitcases, which is why they are used by the police as explosives and drug detection dogs.
  • Currently, a distinction is made between about 350 different dog breeds.
  • Especially intelligent dog breeds are suitable as guide dogs. In a long and intensive training, the dog is taught important commands (such as bringing certain items).
  • Small dogs have a higher life expectancy compared to large dogs.
  • One dog gives birth to between three and fifteen animals per litter. If the female dog is covered by several dogs during the heat phase, it can even happen that the puppies are descended from different fathers.
  • In summer, dogs regulate their body temperature by panting. Because in contrast to humans dogs can not sweat.
  • Dogs are habit animals and therefore always prefer the same sleeping place.
