Here's why:
* Bacteria: Both dogs and humans have bacteria in their mouths. While the types of bacteria can vary, the number and types are not inherently "cleaner" in dogs.
* Disease Transmission: Dogs can carry bacteria that can be harmful to humans, such as Salmonella and E. coli.
* Saliva: Dog saliva contains enzymes that can help break down food, but they don't eliminate all harmful bacteria.
It's important to remember:
* Always wash your hands after petting a dog.
* Avoid letting dogs lick your face or open wounds.
* Keep dogs' mouths clean with regular brushing and veterinary checkups.
In summary, the myth of the "clean dog mouth" is just that - a myth. Both dogs and humans have bacteria in their mouths, and it's important to practice good hygiene around animals to prevent the spread of germs.
