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.
Thus, when a dog pants, it's actually cooling the dog's entire body. The dog's quick shallow breaths cause moisture on the tongue to evaporate thus cooling the tongue that in turn cools the blood flow through the tongue and the respiratory system. Providing your dog with cool air on hot or humid days is very important for temperature regulation.
