Your dog’s tongue is his stomach’s gatekeeper. It encourages him to eat high-calorie foods and deters him from gorging on poison by helping him distinguish between which foods are delectable and which are disgusting.
Look inside your dog’s (and your own) mouth to see the numerous papillae, which are tiny bumps that each contain clusters of taste buds. Each taste bud contains about 50 taste-receptor cells. Dogs have about 1,700 taste buds on average, compared to our 9,000 taste buds.
Different tongue regions have taste buds that react to various microscopic molecules. Like us, dogs can identify sweet, sour, salty, and bitter. Unlike us, they also have unique taste buds designed to only detect water. Water is therefore probably not “tasteless” to dogs as we typically refer to it. The dog’s tongue tip, which it dips into the water and curls under when drinking, has these water receptors.
You enjoy rolling candy around the tip of your tongue because it is the part of the tongue that is most sensitive to sweet tastes in humans. Dogs’ tongues are most susceptible to sweetness in the back. That may be why they seem to gulp them down.
Dogs can taste the food they appear to inhale without chewing because they also have taste buds in the back of their throats.
Compared to people, dogs can’t taste salt very well. This is due to the fact that they evolved to consume meat, which naturally contains sufficient salt to meet their body’s needs without them having to actively seek it out. But they can still taste, and appreciate, salt.
Depending on what they have evolved to eat, different species have different tastes. Your dog has a strong preference for meat, as wolves in the wild consume an average of 80% meat. Dogs love meat, but they are actually omnivores, which means they will consume both plants and animals. They will also consume your glasses, your cat’s waste, your furniture, and pretty much anything else!
According to tests, the majority of dogs favor beef and pork over chicken and lamb. They also prefer warm, moist foods over cold, dry foods.
Of course, just like people, each dog has individual preferences. That may be caused in part by them preferring the food they consumed as puppies. According to one study, a puppy’s future food preferences may be influenced by the food their dam consumed while she was pregnant.
Most dogs prefer variety, so feeding them the same thing every day will make them bored. Give them something new and they’ll gobble it up. Dogs that were raised with no variety at all are the exception. They are wary of experimenting with new foods and frequently appear to avoid doing so.
Give your dog a bowl of a different food every day and observe how much he eats to determine what flavor he prefers. To determine how much he consumed, you could weigh the bowl both before and after he eats. You might try offering two bowls of food side-by-side and letting him choose instead, but what if he licks his bowl clean every day, or what if he’s simply more hungry one day than the next? But again, what if he licks both bowls clean? What if he just keeps eating from whichever bowl he gets to first? What if he only wants to eat from the right-hand bowl or the left-hand bowl? Which one does he eat more of?
Dog food manufacturers must carefully account for all factors that could skew the results when testing hundreds of dogs to determine what flavors they prefer. They can monitor the dog’s consumption of each food item second by second as well as his chewing frequency and bite size. You can do your own taste test at home:

Not all dogs have a pink tongue.
Most of us envision a panting, happy dog with a bright pink tongue hanging out of their mouth. The majority of dogs have pink, moist to slobbery tongues, but the Chow Chow and Shar-Pei dog breeds of Chinese origin have blue or blue-black tongues. It’s possible for hybrids of those breeds to have blue-black tongues or blue-black spots on their tongues.
If your dog normally has pink tongue, a sudden change in color could be a sign of an urgent medical situation.
Call your veterinarian right away if you notice these modifications in your dog’s tongue.
A dog’s saliva won’t exactly “heal” your wounds.
Another myth says that dog saliva can help heal wounds. In fact, some cultures in ancient Greece and Egypt also thought that dog saliva has healing properties. While licking can help clear away debris from a wound and reduce the risk of infection, excessive licking can harm the skin and cause more serious issues like hot spots.
But the ancients weren’t entirely mistaken—histatins, a type of protein found in both human and canine saliva, prevent infection. However, canine mouth bacteria that are common in dog saliva are also present, and these bacteria can cause harmful infections in human wounds.
Therefore, refrain from letting your dog treat your wounds and stick to more conventional methods like washing with soap and water and consulting your doctor about any potential infections.
Dogs’ mouths are not cleaner than ours.
It’s a myth that a dog’s mouth is cleaner than a human’s, not the other way around. Over 600 different species of bacteria have been found in the mouths of both humans and dogs, according to researchers.
But while both of us have mouths full of bacteria that are typical of our species, your dog has bacteria in his mouth that you don’t have, and vice versa. There are some exceptions, so be safe and let your dog kiss you on the cheek instead. The majority of the bacteria in your dog’s mouth cannot make you sick (you won’t get the common cold from “kissing” your dog).
FAQ
How do dogs use their tongue to eat?
The tongue of the dog has numerous functions. The tongue’s primary function is to help food and liquids enter the mouth and throat. The tongue assists in the chewing and swallowing of food. It functions as a ladle for putting liquids like water into the mouth while drinking.
Do dogs pick up food with their tongue?
Typically, dogs use their teeth to pick up kibbles and swallow them whole or after grinding them. Cats can take kibbles with their tongue, teeth or lips. They either swallow them whole or break them into small pieces by rolling them with their tongues toward their molars.
How does a dog’s tongue work?
They take in more water as they splash their tongues more vigorously. Dogs’ tongues can move out of the water at up to 4 mph (or 1 mph). There is a pressure difference between the tongue and the water’s surface at 8 meters per second. Consequently, a column of water rises in front of the tongue.
What is special about a dogs tongue?
Taste buds Despite the fact that dogs primarily identify and select food based on smell The majority of the taste buds on a dog’s tongue are used to detect bitter, salty, sweet, and sour flavors. A dog’s tongue has many more taste buds than a cat’s, but far fewer than a human’s does.
