Dogs have been used in the police force and in the armed forces from centuries. They are smart and loyal and braver than a lot of people. But at times they will have to go to places that may not be the safest. At times, the air can have toxic gases and other pollutants that can harm the animal. This necessitated the invention of dog masks. They have been popular since they came into use and are still in use.

A lot of models have been designed so far. Initially, the models looked very uncomfortable and tight but better technology has been used to make dog masks more effective and comfortable for the animal it is put on. The masks are designed such that the dog can see through it easily and it will have to be fitted for every dogs as they can have different sizes.
