At the Fresno Bully Rescue, workers prepared the dogs for the frosty temperatures Monday night.
Tarps were attached to each of the kennels to block any wind.
They also moved dog houses into the kennels with several thick blankets inside each dog house.
Then each dog is covered in a warm sweater.
During the cold months the bulldogs recieve puppy food to increase the amount of fat in their diet.
The Bully Rescue says they could always use donations of old blankets and dog sweaters in large or extra-large sizes.
