Do you smooch your pooch?
Lots of dog moms and dads do. After all, their mouth is cleaner than yours, right?
Think about it — what they eat, what they lick. Common sense tells you it’s a germfest.
But the truth is, those bacteria aren’t big health risks for most people. So kissing your furry baby is OK, if it doesn’t gross you out. Just have a healthy awareness of what could be in your dog’s mouth, says Clark Fobian, DVM, president of the American Veterinary Medical Association.
What has your dog been doing?
Before you kiss a dog, or let a dog kiss your face, “you have to think of where their nose has been,” Fobian says. “Has it been inside a dead opossum on the side of the road, or the posterior of another dog, or in the litter box?”
Don’t think that kissing your dog on their snout or the top of their head is safer than on the mouth. When a dog has an infection — say, in their ear — germs can end up all over their body through scratching, Fobian says. And there’s a good chance whatever’s in their mouth will end up on their coat through slobber and licking.
Could you make each other sick?
Human and dog mouths have “a large number and a wide variety of bacteria,” Fobian says. Fortunately, most of it doesn’t make us sick, but some can. Parasites like hookworm, roundworm, and giardia can be passed from dog to human through licking. Salmonella, too, can be passed from your dog to you, or vice versa.
Viruses tend to affect one species or the other; you’re not going to give your dog a cold, and they won’t be giving you their cough.
If you’re sick, think twice
If you’re not healthy, skip it. People with weak immune systems should simply avoid kissing pets, Fobian says. That includes those with HIV/AIDS, those who have had an organ transplant, and those who are on medicines for cancer that limit the body’s ability to fight off infection.
Get the message from your dog
Some dogs may not like you to put your face close to theirs.
A dog who doesn’t want to be kissed will show their stress by leaning away, looking away, pursing and licking their lips.
“A lot of people miss those signs, and when they try to kiss the dog, the dog snaps at them,” says Melissa Bain, DVM, assistant professor at UC Davis School of Veterinary Medicine.
If your dog is giving you signs that this is not their thing, then don’t put them through it, Bain says.
It’s not much different from trying to kiss a human who doesn’t want to be kissed. “We respect people who are like that; we should also respect dogs who are like that,” Bain says.
