Some people believe that since dogs lick their own wounds to help them heal, they should be able to work the same magic on human cuts and scrapes, too.

The ancient Egyptians used to praise dog saliva for its healing ability. They even had temples devoted to dogs where people would encourage pups to lick their open wounds and heal them from illnesses.

That might seem a little weird now because we know a lot about germs that seems to contradict what the ancients knew.

That is until now.

New research suggests that those puppy kisses may actually be good for you.

Wait, Aren’t There Germs in Dog Saliva?

Just like our mouths are full of germs, your dog’s mouth is teeming with bacteria and parasites that can infect you and your family members.

From salmonella and E. coli to worms and giardia, you have to be careful about your playful dog’s licks all the time. You see, when a dog licks his bum, the nasty bacteria released from his intestines may move from his bum to his mouth.

You’ll be receiving this transfer of nasties every time your dog licks you. Yuck!

Research on Dog Saliva

University of Arizona researcher Charles Raison, MD, believes that dog saliva may have a “probiotic” effect that may help humans “develop healthy bacteria colonies that in turn boost the immune system.”

Maybe they’ll start adding dog saliva to yogurt?

Dog saliva also has lysozyme, which prevents certain bacterias from growing, histatins that help skin cells heal a wound, and nerve growth factor (NGF).  Scientists at the University of Florida discovered that when a wound is doused with the NGF in saliva, it heals twice as fast.

But this evidence is still up for debate.

Psychology Today says that licking a wound may be positive just for the simple act of loosening debris to keep the wound clean so it heals well. After all, a dog can’t bandage his wound himself.

So What Should You Do?

Dogs have been licking their wounds since the dawn of their existence, but you definitely shouldn’t let them lick yours.
