Why do dogs breathe smell better than human breathe?
Question Date: 2016-09-01
Answer 1:

This is up for debate – lots of people complain about their dogs’ breath and many humans work hard to keep their breath from smelling bad. The smells coming from both dogs’ and humans’ mouths are both caused by certain bacteria that eat food residue off our teeth, gums and tongues. As they eat the residue, they release smelly gas and build hard shells on our teeth, called plaque. If lots of bacteria live our mouth for a long time, they can irritate our gums (causing gingivitis), cause bad breath (halitosis) or even eat through our teeth (causing cavities). Brushing, flossing and using mouthwash removes a lot of the bacteria that cause these problems and keeps our mouth healthy – and less smelly too!

Your dog can’t brush his own teeth, which could lead to bad breath, but can cut down on the amount of bacteria in his mouth by drooling and chewing on fiber (like rope toys). Some people also brush their dogs teeth themselves or with the help of a veterinarian.

One reason your dog’s breath may smell better than yours is because dogs eat less sugar – the bacteria in your mouths’ love sugar and produce more gas when they eat it. Also, you many not be able to smell all the chemicals coming out of your dogs’ mouth. Your nose is only able to detect a specific set of chemicals and we are particularly sensitive to our own “bad” smells. We humans use these smells to stay healthy your bad breath tells you to brush your teeth, your stinky feet tell you to wash and air out your toes, etc. We’re less aware of the different ways that dogs smell because we are not dogs. Dogs, however, have both a more sensitive nose and can detect a larger number of chemicals. A dog’s breath and sweat tell other dogs many things about who they are, where they’ve been and how healthy they are.

So, you may think your dog’s breath smells sweet just as your dog wishes he could tell you to brush your teeth.

Answer 2:

Dogs have wet noses, which means that their smell receptors are on the front of their noses instead of inside of their noses.
