Can dogs transmit many diseases to humans? Understanding the related health risks
Dogs can indeed transmit certain diseases, but specific conditions for transmission are required. As long as the dog is kept healthy and does not contract these diseases, humans will not become infected either. Generally speaking, households in large cities are able to meet these conditions. Feed dog food, do not feed raw or contaminated food, vaccinate according to regulations, take the dog for regular health checkups, and pay attention to daily hygiene -- always wash your hands after contact with animal waste. If all of this is done, the possibility of humans being infected by dogs is extremely small.
Although dogs can also have viral hepatitis, their virus is completely different from that of humans, and the dog hepatitis virus will never be transmitted to humans; even if the human hepatitis virus is inoculated into dogs, it cannot infect them. Therefore, the claim that dogs can transmit hepatitis B is purely a false rumor. The most terrifying killer of dogs -- canine distemper -- also does not transmit to humans.
So, it is true that bacteria do exist on cats and dogs, and the possibility of infection does exist when keeping cats and dogs. However, as long as owners take responsibility, ensure that the living environment of family members and pets is hygienic and healthy, and develop correct care habits, keeping pets will be safe.
