Priced at $40 USD, the Fire TV Stick is a bit more expensive than Google's $35 Chromecast, but $10 cheaper than the already-affordable Roku Streaming Stick âlike other typical set-top boxes, the standard Fire TV is available for $100.
The precise question was: Is a dog's mouth cleaner than a human's? The answer to that is no, too, and basically for the reasons you've already cited. As we all know, dogs aren't particularly fussy about where they put their tongues or what goes into their mouths.
Dogs are also prone to eating feces which may contain intestinal parasites such as roundworms or Giardia which can be passed onto humans. If the dog licks the child's skin and then the child puts that saliva-covered body part to his mouth, he could potentially be exposed to various diseases. It is best to minimize your pet's licking of the child, or at the very least try to prevent licking of the face or hands and if occurs wash promptly with baby wipes.
