Is a Dog Mouth Cleaner Than a Human's

The age-old debate about whether a dog's mouth is cleaner than a human's has persisted for years, with strong opinions on both sides. It's a topic that sparks curiosity and often leads to lighthearted discussions among pet owners and enthusiasts. Today, Puainta discusses the facts for you.

Why Do They Say Dogs' Mouths Are Cleaner Than Humans?

The myth may have originated from observations that dogs sometimes lick their wounds and seem to heal relatively quickly. This behavior can be attributed to certain enzymes in a dog's saliva that may have some antibacterial properties. However, this does not mean that a dog's mouth is free from harmful bacteria.

Both dogs and humans have bacteria in their mouths that are specific to their species, and there's a range of bacteria in both that can potentially cause infections. Factors such as diet, oral hygiene, and overall health also play a significant role in the cleanliness of a dog's mouth.

Is a Dog's Mouth Really Cleaner Than a Human's?

Discussing three main aspects of oral bacteria, oral health and diet, and environmental factors.

Is Dog Saliva Antibacterial?

Yes, dog saliva does contain some antibacterial properties, but it's not a foolproof or comprehensive defense against all types of bacteria. Dog saliva, like the saliva of many animals, contains enzymes and proteins that can help break down and inhibit the growth of certain bacteria. One of these enzymes is lysozyme, which can be effective against certain bacterial strains.

Does Dog Saliva Have Healing Properties?

While dog saliva contains enzymes and proteins that could potentially aid in wound healing and have antibacterial properties, there are also factors to consider that might outweigh these potential benefits.

Dog saliva, like any bodily fluid, can contain a mix of microorganisms, including both beneficial and potentially harmful bacteria. Allowing a dog to lick wounds or irritated skin can introduce additional bacteria to the area, which could potentially lead to infection or delayed healing. Additionally, a dog's mouth is not a sterile environment, and their licking might introduce foreign substances that could impede the healing process.

Furthermore, a dog's licking behavior can sometimes be excessive, leading to irritation of the skin or removal of protective scabs from wounds. In such cases, excessive licking could actually hinder healing rather than promote it.

For these reasons, it's generally recommended to avoid allowing dogs to lick wounds or areas of broken skin. Instead, proper wound care and hygiene, as well as consulting a medical professional or veterinarian, are the best approaches for promoting healing and preventing infection.

Can You Get Infections and Diseases From Dog Saliva?

Yes, it is possible to contract infections or diseases from dog saliva. For instance, bacteria like Pasteurella and Capnocytophaga, which is commonly found in the mouths of dogs, can cause skin and soft tissue infections if they enter the body through a wound or broken skin. And Rabies is a viral infection that can be transmitted through the saliva of infected animals, including dogs. 

What's more, Dogs sometimes carry bacteria like Salmonella or Campylobacter in their mouths. If these bacteria are transferred from a dog's mouth to your hands and then ingested through touching your mouth or eating without proper handwashing, they could cause gastrointestinal infections.

How to Keep Your Dog From Licking You?

If you experience allergies triggered by dog saliva or have a weakened immune system, it's crucial to train your dog to refrain from licking or kissing you. While this can present a challenge, effective training is the solution. Should your dog attempt to lick you, promptly stand up and move away. Optimal results come from ignoring your dog's behavior, as this imparts the lesson that licking doesn't yield rewards like your attention or treats.

In cases where you possess open wounds due to injuries, it's equally important to prevent your dog from licking them. Dog saliva contains elements that could lead to infection in your wounds. When dealing with a wound, ensure it's shielded by clothing or a bandage to safeguard it against contact with your dog's saliva.  

There are taste deterrents available that can be applied to your skin or clothing to discourage licking. These products have a bitter taste that dogs find unpleasant.

How to Clean a Dog's Mouth?

• Apply a small amount of dog toothpaste to a toothbrush or cloth and gently brush your dog's teeth in a circular motion. Brush your dog's teeth 2-3 days a week or more (Never use human toothpaste on your dog as it may contain ingredients that are harmful if ingested.)
• Sprinkle your dog's food with dental powder at every meal, following the product directions and introducing it gradually, as some dogs can be sensitive to it.
• Ask your veterinarian about a prescription dental diet for dogs
• Offer your dog dental treats with the Veterinary Oral Health Council seal of approval
• Schedule regular veterinary dental cleanings
