Kansas City Chiefs safety Tyrann Mathieu has teamed up with PETA to create a public awareness video on the dangers of dogs being kept outside in freezing cold weather.

Tyrann stepped into a walk-in freezer to experience what it must be like for dogs left out in the cold.  He pointed out that their food and water also freeze solid when left outdoors in the cold.

Tyrann lasted about 20 minutes, but some dogs are left outside all day and night.

PETA recommends talking to your neighbors if you see that their dogs are left outside in the cold.  You can also see if your local government has a policy on chained dogs.
