Don't leave bad reviews for misuse. That's dishonest. These are NOT designed to keep your dog warm or for COVID-19. Dogs don't ever need or benefit from a mask for such purposes.These are designed for disasters such as reducing smoke or ashes from fires, severe dust, or to reduce environmental contaminants.
