While it's true that dog mouths contain bacteria, not all dog licks are dirty. Here's why:
- Dogs have a different oral microbiome than humans: Their mouths are full of bacteria that help them digest food and protect against infections. These bacteria are generally harmless to dogs, but they can be harmful to humans.
- The amount of bacteria in a dog's saliva varies: A dog's saliva can contain a lot of bacteria if they have recently eaten something dirty or if they have a dental infection. However, a healthy dog with good hygiene will have a lower concentration of bacteria in their saliva.
- The risk of infection from a dog lick depends on the individual: People with weakened immune systems or open wounds are more susceptible to infection from dog licks.
Here are some examples of situations where a dog lick might be considered dirty:
- If the dog has been licking its own feces or urine: These substances can contain harmful bacteria and parasites.
- If the dog has been licking something that is contaminated with bacteria or viruses: This could include things like garbage, dead animals, or other animals' feces.
- If the dog has a dental infection: This can increase the number of bacteria in their saliva.
Here are some examples of situations where a dog lick might not be considered dirty:
- If the dog is healthy and has good hygiene: A healthy dog with good hygiene will have a lower concentration of bacteria in their saliva.
- If the dog has been licking a clean surface: A dog's saliva can actually help to clean surfaces, as it contains enzymes that break down dirt and bacteria.
- If the dog has been licking a person's hand or face: A quick lick from a healthy dog on a clean surface is unlikely to cause any harm.
Overall, it's best to err on the side of caution and avoid letting dogs lick your face or open wounds.
