Should you let your dog lick you? Well, hardcore dog lovers will fight tooth and nail to prove that you should let your dog lick you because that is how they show you affection. This view is not entirely wrong because, after all, which dog-lover would have the heart to push away his canine when it comes to showing love in the only way it can? But emotions are just one aspect of this show of affection. The other aspect that a dog-lover should consider is the health issues associated with a dog's saliva. It is difficult to say whether a dog's saliva is good or bad- and if it is good, then exactly how much of it is good? In this post, we shall present five facts for you to consider. The aim is not to make you stop your dog from showing you some love- rather, it is only to make you more aware.

Dog Licks Can Cause Allergic Reactions

Dog saliva contains at least 12 different allergy-causing protein bands. These proteins become airborne when the saliva dries on the fur, potentially triggering allergic reactions in susceptible individuals. This makes dog saliva a significant allergen source, often more so than dog dander.

While many people consider dog dander the primary cause of pet allergies, dog saliva has a greater potential as an allergen source. The proteins in dog saliva can provoke allergic responses, especially when they become airborne and inhaled by humans.

The specific protein profile in dog saliva differs between dogs, making some dogs' saliva more allergenic to certain humans. This variability means that the allergic potential can vary widely depending on the dog breed and individual dog's saliva.

Dog Saliva Has Antibacterial Properties

Certain proteins in dog saliva, such as histatins, have antibacterial properties that can defend against infections. These antimicrobial enzymes can help clean wounds and reduce the risk of bacterial infection.

There is evidence suggesting that wounds licked by dogs may heal twice as fast due to the antibacterial properties in their saliva. The healing properties of canine saliva can be beneficial in certain situations, promoting quicker recovery of minor injuries.

Despite its antibacterial benefits, dog saliva can also pose risks. The moisture, inflammation, and bacteria in saliva can sometimes slow healing or worsen infections. Veterinary medicine advises that medical attention from a vet is recommended for any bite wound or animal bites, and using collars or bandages may prevent excessive licking and potential complications.

You Can Get Parasites and Diseases

Dogs and humans share only 16.4% of identified microbes in their oral microbiomes. While this limits the overlap, the unique bacteria present in dogs' mouths can still pose a risk to human health, particularly in high-risk groups like immunocompromised individuals, young children, and the elderly. Dogs and cats both carry bacteria in their mouths that can cause infections in humans.

Dog kisses and dog licks can transfer bacteria to humans. The bacterial cell membranes in dogs' mouths can harbor species that can be transmitted through close contact, potentially leading to infections in humans.

A dog bite can introduce the bacteria Capnocytophaga canimorsus through the wound, potentially leading to a severe bacterial infection in humans. Another prevalent bacterium, Pasteurella canis, is commonly found in a dog's mouth and is frequently identified in individuals bitten by dogs. This emphasizes the importance of being cautious with dog bites and close contact with dogs' saliva.

Intestinal parasites like Giardia, hookworms, and roundworms can be present in dog saliva and transmitted to humans, though this is rare. Maintaining proper hygiene and regular veterinary check-ups for your dog can help mitigate this risk. It’s crucial to monitor for clinical signs of infection and seek medical attention if symptoms arise.

Zoonotic infections, diseases transmitted from animals to humans, can also occur through dog bites and saliva. Healthy dogs might still carry bacteria such as Escherichia coli that can infect humans. Therefore, it is essential to be aware of the potential risks and take preventive measures.

Canine Saliva Prevents Cavities

Dog saliva is slightly alkaline, which helps prevent cavities. The pH balance in their saliva creates an environment that inhibits the growth of bacteria that cause dental issues, keeping their teeth healthier.

Despite its cavity-preventing nature, dog saliva does not prevent periodontal disease without active prevention measures like toothbrushing. Regular dental care is essential to prevent gum disease and maintain overall oral health in dogs.

It Plays a Different Role in Digestion

Unlike human saliva, dogs’ saliva does not contain amylase, an enzyme that aids in the digestion of carbohydrates. This difference means that dogs rely on their stomach and intestines to break down food.

Dogs' saliva primarily serves to move food down the esophagus, facilitating swallowing rather than beginning the digestive process. The majority of digestion occurs in their stomach and intestines, making their digestive process different from humans.

Understanding the various aspects of dog saliva can help pet owners better manage their interactions with their pets. While dog saliva has beneficial properties, such as antibacterial effects and cavity prevention, it poses potential risks, including exposure to allergens and disease transmission. Proper hygiene, regular veterinary visits, and awareness of these factors can help ensure a healthy relationship between you and your furry friend.

If you notice any signs of infection or if you or your pet are bitten, seek medical attention promptly. Antibiotics may be necessary to treat infections caused by bacteria in dog saliva. As a pet owner, it’s crucial to stay informed about the health and risks associated with dogs and cats, ensuring both your safety and the well-being of your animals.

Frequently Asked Questions

How healthy is dog saliva?

Dog saliva is generally considered to be relatively healthy, although it is not entirely devoid of potential risks. Saliva serves several functions in dogs, including helping in the digestion process, keeping the mouth clean, and providing a moist environment for the healing of wounds. It contains enzymes like lysozyme, which can help combat bacteria and promote oral hygiene. Additionally, dog saliva contains immunoglobulins that contribute to the immune system's defense against pathogens. However, it is vital to exercise caution when it comes to dog saliva due to potential health concerns. Dogs may carry certain bacteria in their mouths, such as Pasteurella, Capnocytophaga, and Eikenella, which can all be transferred through bites, licks, or scratches. While these bacteria rarely cause infections in healthy individuals, they can pose a risk to people with compromised immune systems or those with open wounds.

Is it safe for a dog to lick your face?

There are dangers and factors to think about before letting a dog lick your face. Even while many people find it pleasant and see it as an expression of love, it's crucial to be aware of any potential health risks. Dogs' mouths can contain parasites and germs that might be dangerous to people. Although there is typically little chance of getting an illness from a dog lick, there is still some chance. A dog's mouth may include some bacteria, including Pasteurella, Capnocytophaga, and Eikenella, which may cause infections if they get into the body through open wounds or mucous membranes. Dogs can unintentionally spread parasites like fleas and ticks by licking. People with weakened immune systems and those who have injuries or sores are more vulnerable. It is advised to avoid excessive face licking and practice excellent hygiene, such as washing your hands and face completely after dealing with dogs, especially in places where there may be sensitive skin. In the end, it comes down to personal preference, but being aware of the dangers and implementing the appropriate safety measures will help prevent any potential health problems brought on by dogs licking faces.

Why do dogs lick human wounds?

Dogs may instinctively lick human wounds due to a combination of natural behaviors and their innate desire to provide comfort and promote healing. First off, licking is a self-soothing habit for dogs, similar to how people can massage or touch an uncomfortable spot. Dogs lick wounds to release endorphins, which can lessen tension and soothe pain. Dog saliva also includes certain enzymes, such as lysozyme, which have antibacterial qualities and can help clean the wound. Additionally, dogs groom themselves by licking, and they may attempt to clean and remove unwanted objects from the wound out of instinct. Additionally, the wetness from the dog's tongue can offer a somewhat hydrating and protective environment for the wound, promoting faster healing. It's crucial to remember that extended licking could hinder wound healing by introducing more germs or irritants and may even result in infection. Therefore, it is advisable to monitor and manage a dog's licking behavior by employing appropriate wound care techniques, using protective coverings if necessary, and consulting with a veterinarian for guidance on wound management and healing.

Should I let my dog lick my feet?

The final decision on whether to let your dog lick your feet is up to you and your particular preferences and circumstances. There are a few things to bear in mind, though. The first thing to remember is that canine saliva could include bacteria or parasites that might possibly be passed on to people. Although the likelihood of getting an infection from a dog lick is often minimal, persons with weakened immune systems, open sores, or skin disorders may be more vulnerable. It might be better to forego having your dog lick your feet if you have any health issues of your own or if you fall into one of these higher-risk categories. Additionally, some people may find foot licking uncomfortable or undesirable due to personal preferences or hygiene concerns. If you choose to let your dog lick your feet, it's important to practice excellent hygiene by washing your feet well both before and after to reduce any possible hazards. Regular veterinary treatment for your dog, such as immunizations, parasite prevention, and dental care, will also lessen any potential health risks brought on by dog saliva. However, in the end, it's up to you whether or not to let your dog lick your feet, but it's crucial for your health to think about the dangers and take precautions to avoid them.
