What Bacteria Lurks in Your Dog’s Mouth?

The type of germs in your dog’s mouth depends on the degree of dental illness they have because your dear fido’s teeth contain plaque and biofilm that grow over time.

Additionally, other aspects such as diet, genetics, hygiene and environmental exposure can enhance the stay of bacteria and other infectious microorganisms in your pet’s mouth. 

So, what are the types of bacteria that are common in your furry friend’s mouth?

  • Pasteurella is a common bacteria found in a dog’s mouth that causes skin and lymph node infections and more severe diseases. You can contract Pasteurella by allowing your dog to lick your wounds or when a dog bites you.
  • Bartonella henselae can be transmitted to dogs from infected lice, ticks and fleas via their poop. Although it can be transmitted to people through cat scratches, it’s not clear if dogs can also pass it to humans, according to the Centers for Disease Control and Prevention.
  • Intestinal bacteria in pets such as Salmonella, E. coli, Clostridia, and Campylobacter can cause intestinal diseases in humans. Even if your pet does not show any symptoms, harmful germs can be found in their poop. 

Can You Get Parasites From Letting Your Dog Kiss You?

Yes, you can get parasites from letting your dog kiss you. Dogs can host many parasites, and some could have mild effects on your dog, which may not show signs. As a result, you could be misled to assume that kissing your dog is safe.

However, you can get infected through your dog’s excrement. For example, if a dog licks their anus and then licks your face, you’ll be at risk of contracting the parasite. But unless the eggs have matured, this type of infection is unlikely.

So how can you avoid getting infected? Below are some ways to prevent getting infected when you come into contact with your companion friend:

  • Wash your hands thoroughly after coming in contact with your dog
  • Examine your pet’s faeces and deworm them regularly 
  • Regularly wash your dog to protect them from fleas and ticks
