The safe and precise temperature range for all types of dogs to walk is from 15 to 18 degree centigrade. When the temperature is between 20 to 25 degrees, healthy medium and large dogs can walk for 15 to 20 minutes. When the temperature falls below 15 degrees, make sure you don’t walk senior, small, and sick dogs. When the temperature touches zero degrees centigrade, then it is a BIG NO for any type of dog to walk.
