The Coalition to Unchain dogs works to improve the the quality of life for dog living continuously chained up outdoors.
A video released last month, shows volunteers coming to the aid of two dogs, 'Mama' and 'Oreo' who are living chained up in the rain.
The volunteers spend the day building an enclosure so the dogs can safely roam around without being chained up.
The dogs' reaction when they are finally freed is priceless. Try not to cry!
