Normally a human cannot get a dog virus like canine influenza or parvo. However, people can catch viruses through exposure to dog feces and the unsafe handling of sick or infected dogs. The dog virus a human can get is rabies. A bite from an infected dog is usually how the virus is transmitted. Though it is rare, a person can also get rabies if the saliva from an infected animal gets into their eyes, mouth or an open wound. When handling dogs, be aware that you can get parasites such as ring or tape worms, too.
