Despite the numerous positive effects of dogs on the physical and mental health of humans, we should not ignore the fact that dogs can be a source of various zoonotic pathogens. Dog owners very often consider their dogs as members of the family and accordingly achieve very close contact that favors the transmission of zoonotic pathogens. Bacterial zoonotic diseases associated with pets are a relatively neglected area, and there is a general lack of data on the prevalence of pathogens within the pet population, or the frequency of infections in humans that can be linked to transmission from pets. This paper presents the most common bacterial zoonoses in dogs. An overview of their frequency, mode of transmission and associated preventive measures is given. The different modes of transmission and associated preventive measures are presented. Bacterial zoonoses are divided into those that are transmitted by bites, scratches or contact with saliva (infection with Pasteurella spp. and Capnocytophaga canimorsus), fecal-oral route (salmonellosis, campylobacteriosis), direct or indirect contact with animal tissues, urine (leptospirosis), other body liquids or secretions (brucellosis, Q fever), by droplet or aerosol (infections with B. bronchiseptica, Q fever). Separate chapters briefly review the importance and zoonotic potential of multidrugresistant bacteria and vector-borne diseases.
