Under normal circumstances, dog saliva is not harmful to people, but if a dog licks a wound on a person, it may cause infection and inflammation of the wound, because the dog's mouth contains a large number of bacteria. If you have a rabid dog, the rabies virus will also be present in the saliva, so you need to pay more attention.
Tips:
If the dog is injured, try not to let the dog lick it. The dog needs to be vaccinated, bathed, and Deworm, brush teeth, and pay attention to your dog’s hygiene.
