There’s no doubt dogs are affectionate creatures. And they have numerous ways of showing it. So what’s the deal when your furry friend comes up and gives you a big ol’ pooch smooch? Let’s take a tongue-in-cheek look into why.

Dogs are oral creatures and gather a lot of information about their surroundings through taste and smell. Maybe you’re salty after a sweaty run. Maybe you’ve got barbecue sauce on your face. “Dogs can smell a lot better than we can,” says Opens a new windowDr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute, “so they find a lot more things interesting to lick than we can.” This despite the fact dogs only have about 1,700 taste buds compared to around 9,000 in humans.
In a poll* of dog owners, IAMS™ found a large majority (75%) believe dogs lick people to offer friendliness. That’s definitely a correct assumption. Licking has been a social behavior among dogs since the days of great-great-great granddaddy wolf. 'It’s a standard canine greeting to lick others around the face,” agrees Opens a new windowJames Serpell, B.S., Ph.D., Professor of Humane Ethics & Animal Welfare at the University of Pennsylvania School of Veterinary Medicine. “Junior members of the pack will run around and lick the mouths of more senior members.” Your dog considers you part of their pack, so it’s their way of greeting and welcoming you. Or maybe you still have that barbecue sauce on your face.
In ancient Greece, dogs at the shrine of Asclepius were trained to lick patients. In the Middle Ages, Saint Roch was said to have been cured of a plague of sores through his dog’s licks. The French even have a saying, “langue de chien, langue de médecin,” which translates to, “a dog’s tongue, a doctor’s tongue.”

Don’t cancel your health insurance just yet. While dogs’ saliva does have some possible bactericidal properties against some types of bacteria, it can put you at the risk of exposure to others. Too much licking can also reopen the wound and cause further infection. With modern medicine, you’re much better off hitting the first-aid kit.
And that myth about dogs’ mouths being cleaner than humans’? Not true — both contain over 600 types of bacteria. You’re welcome for that image.
While an occasional canine kiss is “aww”-inducing, some dogs can overdo it to the point of annoyance. When this happens, the best thing to do is “completely ignore it and give no attention,” suggests Dr. Jo Gale. “When they stop, provide them with attention.” Over time your dog will learn to scale back on the smooches.

Not all small dogs have the same nutritional needs. Giving your dog a food specially formulated for her size and activity level is the easiest way to make sure you’re providing complete and balanced nutrition. Here’s how to provide the right nutrition for your small dog.
Small adult dogs require a food that offers complete nutrients essential for health and vitality. Here’s what to look for:
These ingredients are the keys to nutrition whether you feed dry or wet dog food or give your dog treats.
Small dogs have small mouths and stomachs. You may want to feed your dog a formula with a small bite size for easy chewing. A nutrient-dense food will help make sure she’s absorbing essential nutrients even though her stomach can only accommodate what seems like a small volume of food.
When choosing a food for your small-breed dog, also ask:
Special conditions like these dramatically affect your dog’s nutritional demands.
Less-active dogs and dogs who have been neutered or spayed are prone to weight gain. Controlling your dog’s weight is an important step toward protecting against complications of excess weight, such as diabetes or joint health problems. If you use a weight-control food, look for these ingredients:
Starting in the seventh week of her pregnancy, a mother dog will need to increase her energy intake up to 50% by the time she gives birth and increase it even more when she starts nursing her puppies. Because she may lose her appetite at times, it’s important that she eats a nutrient-dense food. A complete, balanced small-breed puppy formula can give her the extra nutrients she needs.
Unlike larger dogs that are considered mature at age 5, your small dog can remain on an adult diet until age 7. In fact, small-breed dogs tend to live longer and don’t experience age-related changes as early as bigger dogs. However, it is important to make a proactive transition to a specially formulated mature diet, such as IAMS™ ProActive Health™ Mature Adult Small & Toy Breed, so you can help keep your dog healthy and active for years to come.
