Hunting dogs are very often exposed to various bacterial diseases due to their movements in forest areas hunting wild animals. Bacterial diseases are present in the environment, but wild animals can also carry the infection and pass it on to dogs. The most common bacterial diseases affecting hunting dogs are: leptospirosis, brucellosis, salmonellosis, yersiniosis, bacterial dermatitis and bacterial diseases transmitted by ticks. In addition to dogs, diseases are also dangerous for humans because zoonoses are a group of infectious diseases that are common to humans and certain animal species, and can be transmitted from animals to humans and from humans to animals. The vectors do not have to be only wild animals, they can also be domestic animals. It is very important to react in a timely manner, determine the source of infection, diagnosis and prevent the spread of the disease, but also treat the infected animal correctly in order to avoid fatal outcomes. Nowadays, various researches and the development of medicine have been greatly expanded, so diseases whose treatment and implementation of preventive measures are very successful are discovered very often and in a timely manner. With a timely reaction, bacterial diseases are in most cases treated without major consequences for humans and animals.
