Do dogs have cleaner mouths then cats?

A cat's mouth is cleaner.

The average cat mouth has about 16-18 different types of bacteria, while the dog mouth has over 60 different types.

They tend to have less because they open their mouths less often, thus not attracting so many microorganisms from the outside world, while the dog is constantly panting and breathing heavily through their mouths.

Another reason because of this is that dogs tend to lick and bite things more than cats, whether it's exploring a new object or person that came into the house, drinking toilet water, or eating dirty socks. Cats, on the other hand, sniff and paw things when they want to play and only occasionally bite.

A cat's mouth is also cleaner because of their eating habits.
