It’s a common belief that a dogs mouth is cleaner than a human’s mouth. But is there any truth to this? Let’s debunk this myth and understand the reality.

The Myth and Its Origin

Many dog owners have probably been told at some point that a dogs mouth is cleaner than a human’s mouth. The myth likely originated from the idea that dogs lick their wounds, and their saliva has some antiseptic properties. However, this belief fails to consider several important factors.

The Reality Behind a Dogs Mouth

Contrary to popular belief, a dog’s mouth is not cleaner than a human’s mouth. In fact, a dog’s mouth contains a variety of bacteria, just like the human mouth. Dogs explore the world through their mouths, often licking various objects and even eating things they shouldn’t. This exposes their mouths to bacteria that can be harmful to both dogs and humans.

A study published in the journal Veterinary Record measured the oral bacteria of both dogs and humans and found that there was a significant overlap in the types of bacteria present in both species. While dogs do have some species-specific bacteria, they also share many bacteria species with humans.

Differences in Oral Hygiene

One possible reason for the misconception that a dog’s mouth is cleaner is due to the differences in oral hygiene practices. Humans brush their teeth at least twice a day, floss regularly, and visit the dentist for cleanings. On the other hand, most dogs do not have the luxury of regular brushing and dental care.

Poor oral hygiene can lead to dental problems such as plaque buildup, tartar, and gum disease, both in humans and dogs. However, it’s important to note that these dental issues are preventable in both species with proper oral care.

Health Risks Associated with Dogs Mouth

While dogs’ mouths do have natural mechanisms to kill some bacteria, it doesn’t mean that they are entirely clean. In fact, there are certain risks associated with a dog’s mouth that dog owners should be aware of:

• Zoonotic Diseases: Dogs can transmit certain bacteria, parasites, and viruses to humans through their saliva. Some examples include Campylobacter, Salmonella, and Leptospira, which can cause severe illnesses in humans.
• Allergies: Dog saliva carries allergens that can trigger allergies in susceptible individuals, leading to symptoms like itching, redness, and swelling.
• Wound Infections: If a dog licks an open wound, it can introduce bacteria into the wound and increase the risk of infection.

Conclusion

While the idea that a dog’s mouth is cleaner than a human’s mouth may seem appealing, it is simply a myth. A dog’s mouth contains bacteria, and there are health risks associated with close contact between a dog’s mouth and a human. Therefore, it’s essential to practice good hygiene for both yourself and your furry friend, including regular dental care and avoiding close contact with your dog’s mouth when they’re licking or in the presence of open wounds.
