14 Rare Facts About Dogs

  1. Have you seen how sometimes dogs press their tail in front of their fellow tribesmen? From the outside, it may seem that the animal expresses fear in this way. But this is not the case. The dog's tail covers the scent glands.

  2. Research has shown that dogs can actually be jealous. Their body produces the hormone oxytocin (the same as in humans), which is associated with the ability to express love and jealousy.

  3. Cognitive abilities in dogs are much more developed than it might seem at first glance. Studies have shown that dogs can memorize 150 to 250 words, which is comparable to the vocabulary of a two-year-old.
