Is Tug-of-War Bad for Your Puppy?
Quick answer
No — controlled research found winning or losing tug-of-war does not affect the "dominance" dimension of the dog-owner relationship; a more useful finding is that who initiates play matters more than who wins.
The Popular Worry, and What Research Actually Found
A study found dogs allowed to win repeated tug sessions showed no consistent difference in the dominance-related dimension of their relationship compared to dogs made to lose.1 The popular caution isn't supported.
The More Genuinely Useful Finding
A follow-up study found dogs that initiated most of their play sessions themselves scored lower on amenability and were more likely to show aggression-related behavior in the broader relationship assessment.2 A real, specific reason to be the one who initiates and ends tug sessions.
How to Play Tug Reasonably
- You initiate and end sessions.
- Teach a reliable "drop it"/trade cue (see existing Teaching Drop It).
- Winning or losing occasionally is fine.
- Watch arousal (see Puppy Play) and end before it escalates.
- Guarding behavior around the toy specifically is different — see existing Aggression or Play.
