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 have an additional organ in their nasal cavity known as Jacobson's organ. This organ's function can best be described as a combination of taste and smell. Dogs can literally taste the air. A dog that is experiencing this taste/smell experience usually holds his mouth in a semi-open position that resembles a grin. Scientists call this reaction a Flehman Reaction.
