What's the difference between "tug" and "pull"?

Rebecca

"Tug" and "pull" are very similar and often interchangeable, however there is a slight difference in nuance. To "tug" usually means to gently pull on something, or pull very softly. To "pull" is usually a little bit stronger and refers to using more strength to pull something. Ex: The dog is tugging on the rope. Ex: The horses pull the sleigh.
