Dog saliva has bugs and bacteria in it that can spread through their sloppy kisses -- no matter how cute the dog is, the Wall Street Journal reported.
Most notable potential affects are gastrointestinal problems, including food poisoning and salmonella.
The best way to avoid any potential illnesses is to make sure all animals are up to date with vet appointments. Even then, people younger than 5 and older than 65 are most susceptible to health concerns, Sykes said. It's uncommon for healthy adults to get sick from kissing their dogs.
