Doctors are now warning people against kissing their dogs because doggie kisses can spread salmonella, ringworm and in some cases, bacteria that causes gum disease.

Dr. Khaled Kasem says,  “Dogs aren’t known for their hygiene. They don’t (usually) brush their teeth or rinse with mouthwash, and they’ve probably never visited a dentist. Their daily routine consists of eating leftovers on the floor, licking their bum, and checking out dead animals left on the pavement. Ultimately, their mouth is filthy. Such activities result in a build-up of bacteria in your dog’s mouth, and although the majority is probably harmless, they can pick up parasites and bacteria that can make humans ill. Whether they’ve drunk contaminated water or sniffed animal waste, these bacteria will not boost your immune health as some have argued. Not only can human infection with pet parasites cause a wealth of intestinal diseases, but it also transfers damaging bacteria to your teeth and gums, causing gum disease. If left untreated, the jawbone can decay, opening up spaces in between the gums and teeth – resulting in tooth loss.”
