Why does my dog do that?
Why does my dog growl during play with other dogs or with me?
Last updated 23 September 2026 · How we write and check this
Short answer
Play growling is a normal, common sound during rough and tumble games, distinct in pitch and rhythm from a defensive growl, and dogs use it much the way people might shout excitedly during a competitive game without meaning anything hostile by it. The surrounding body language, loose versus stiff, is what tells the two apart reliably.
How play growling sounds and looks
Play growls tend to be higher pitched, choppier, and interspersed with panting, open mouthed grins, and bursts of movement, chasing, wrestling, tugging, rather than the low, steady, sustained tone of a defensive growl. A dog play growling will typically also offer repeated play bows and self interrupt to check the other dog or person is still enjoying the game.
A normal, even useful part of play
Growling during tug of war or wrestling helps dogs express excitement and intensity within a game both parties have agreed to, similar to how competitive shouting works between people, and stopping a dog every time it growls during clearly enjoyable, mutual play is generally unnecessary and can even confuse a dog that is behaving appropriately.
When to pause and check
If growling shifts toward a lower, steadier tone, or either dog's body stiffens, ears pin back with a hard stare, or one side stops trying to reengage, pause the game and let both dogs reset before continuing.
Key takeaways
- Play growling is higher pitched and choppier than a defensive growl.
- It normally comes with loose body language, play bows, and mutual reengagement.
- Growling during agreed upon games like tug is a normal expression of excitement.
- A shift toward stiffness or a lower, steady growl is the cue to pause and reset.
