Wild diseases can also be transmitted to dogs and from them to humans. They pose a significant risk, especially for hunters and their families. New diseases are spreading due to climate change. Maintaining wildlife health is becoming an increasingly important task for hunting, particularly concerning the quality of game meat. The second part of the book focuses on dog diseases, their recognition, preventive measures, and first aid for dogs. Not only hunters who have direct contact with the hunted game can contract zoonoses, which are diseases transmitted from wildlife to humans. Such diseases can also be transmitted to children and other family members through hunting dogs. Therefore, a significant section is dedicated to self-protection against infections originating from animals.
