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.
The surface of the tongue is covered with taste buds and it's kept loose and moist by saliva. It is well supplied with nerves and blood vessels, making it one of the most important muscles of the dog's body. In addition to lapping up water and food, a dog's tongue is a heat regulator. That is, when a dog runs around and gets hot, the tongue hangs out to cool them down.
