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 a remarkable ability to discern and remember scents, far superior to that of a human. A dog's sense of smell may be as much as 100 times better than ours, making it the most sensitive and vulnerable part of its body. The human nose has only three-square centimeters of olfactory membrane where some dog breeds, such as Bloodhounds, have as much as 150 square centimeters of scent-sensing material in their noses.
