Wag the White Part

The trick is in the voice
By Karen B. London PhD, February 2014, Updated June 2021

“Are you such a good dog? Can my sweet girl wag her tail!” It’s lovely to see a dog respond to these questions with a great big tail wag. It’s even more charming if she can take it a step further by performing one of my all time favorite behaviors. Here’s a description of the next step.

The person continues by saying, “Now listen very carefully because instead of wagging your whole tail, I want you to wag just the white part.” When the dog wags just the white part at the tip of her tail, it’s a real crowd pleaser.

Of course, this particular format of the trick requires that the dog’s tail is white at the tip only, and that is only true of some dogs. For dogs whose tail has no white at the end, you need to change your phrasing, perhaps saying, “Wag just the tip” or “Now just give me a little wag” but the dog’s behavior is the same.

It is possible to train a dog to wag her tail in response to the cue “Wag your tail” and to wag only the tip of the tail when she hears, “Just the white part.” However, some dogs will perform the behavior you want without really being trained to do so. The secret is in the enthusiasm of the person’s voice. When you say something along the lines of “Are you such a good dog? Can my sweet girl wag her tail!”, you need to say it in the overly exuberant manner that we all have when praising or greeting our dogs. It’s that enthusiasm that is going to make your dog wag her tail whether she’s been trained to do it on cue or not.

Then, to elicit the small, just-the-tip tail wag, you completely change your tone of voice, becoming very serious and talking more slowly, quietly and slightly deeper. So, when you say, “Now listen very carefully because instead of wagging your whole tail, I want you to wag just the white part”, the key is not what you say, but how you say it. Many dogs will respond to the change in your energy level by dialing back their tail wag to a less lively one, and for dogs with a white-tipped tail, that makes it look like they are cleverly responding to your instructions to wag only the white part.

Some dogs reliably do this the first time and every time, but in other cases, it takes some trial and error to figure out exactly what tone of voice and level of enthusiasm prompt the dog to exhibit the right amount of tail wagging for each part of this trick.

How does your dog’s tail respond when you vary your tone of voice and level of enthusiasm? Do you have a wag-the-white-part (or a wag-just-the-tip) dog?
