Dogs pose a minimal risk for transmitting a disease.
Dogs, particularly puppies, however, do carry some diseases that could be harmful to someone at higher risk. Parasites which dogs can transmit to people include roundworms, hookworms, whipworms, cryptosporidia and Giardia . In rare instances, dogs can also transmit bacteria such as Salmonella and Campylobacter . These parasites and bacteria are most often associated with puppies or with adult dogs who are in unsanitary environments. Any new dog or any dog having diarrhea may need to have his or her stools tested for these infections by a veterinarian.
