Why of the Wag

How to interpret dog tail wagHow to interpret some common dog tail wags.

Perhaps the most common misinterpretation of dog behavior is the myth that a dog wagging its tail is happy and friendly. While some wags are associated with happiness, others can mean fear, insecurity or even a warning that if you approach, you're apt to be bitten. Here's how to interpret some common tail wags:

A slight wag, usually seen during greetings, is a tentative "hello there" or a hopeful "I'm here."

A broad wag is friendly: "I am not challenging or threatening you." It can also mean, "I'm pleased" - the closest to the popular notion of the happy wag, especially if the tail seems to drag the hips with it.

A slow wag with tail at "half-mast" is less social than most other tail signals. Generally speaking slow wags with the tail in neither a particularly dominant (high) nor a submissive (low) position are signs of insecurity.

Tiny, high-speed wags that give the impression of the tail vibrating are signs the dog is about to do something -- usually run or fight. If the tail is held high while vibrating, it's most likely an active threat.

    That is very timely information. Our dog was growling and snapping its teeth at a strange dog that wandered onto our property today but her tail was wagging also, and I wasn't sure really what signal she was giving. The strange dog moved on and no harm was done.
