Every year in Poland, 3 000-5 000 people are bitten by dogs, and a dozen people or so must undergo hospital treatment. Despite common belief, pure-bred dogs are not the main culprits, but mongrels and dachshunds. 300 cases are caused by domestic cats. Pet’s mouths contain teeth, but also tens of germ species. Not only do animals bite. 3.6-23% wounds requiring medical advice were caused by human bites.
