Since ancient times, dogs have been a symbol of devotion and unconditional love. They were the first companions of a prehistoric man, and since then many great ones have noted the positive qualities of these animals. Roald Amundsen, who opened the South Pole with a dog sled, said that dogs have a soul; Remarque’s pets gave him a “feeling of home”, and Agatha Christie even dedicated the novel “Silent Witness” to her fox terrier Peter.

So we decided it’s time to devote an entire article to some dog facts.
