Is Your Dog Left- Or Right-Pawed?

Is your dog left- or right-pawed, or ambidextrous?  Why would you want to know, other than that it is fun to find out?


Here is some interesting data related to paw preference.
  • Left-pawed dogs (18% of population) are more likely to be male.
  • Left-pawed dogs have a weaker immune system response compared to right-pawed or ambidextrous dogs.
  • Right-pawedness (57% of population) is more common in female dogs. 
  • Ambidextrous dogs (25% of population) show no sex bias. 
  • Ambidextrous dogs are much more likely to exhibit noise, thunderstorm phobia and separation anxiety than their left or right handed cousins.
Knowing your dog's paw preference can help with prevention or mitigation of specific issues presented above.

How do you find out whether your dog is left- or right-pawed?

You will need:
  • Some soft dog food – your dog’s regular brand is less likely to cause a stomach upset than anything else.
  • A Kong® (or similar) toy.
  • A sheet of paper numbered from 1 to 50.
  • A pencil.
  • Plenty of time. This test can take up to four hours.
How it's done:
  1. Pack the Kong® with food, and freeze it solid. To start the test place it in front and to the center of your dog’s paws.
  2. Record the paw used to first touch the Kong® at number 1 on the recording sheet.
  3. Continue to record the paw used to touch the Kong® until the dog has made 50 paw interactions classified as left paw (L) or right paw (R). Definitions for the way in which interactions are classified as L or R appear below (interactions with both paws placed separately on the Kong® at the same time are not counted).
  4. If the dog repositions its paw or paws on the Kong®, without the paw or paws completely leaving the
    Kong®, that interaction with the apparatus is not counted or recorded.
  5. If the dog holds the Kong® down with a certain paw or with both paws for longer than 10 seconds, gently remove the Kong® from under the paw or paws and place it in front and to the centre of your dog’s paws.
  6. Some dogs retrieve only the top layer of food from the Kong®. For these dogs, the Kong® must be topped up with food to achieve the 50 paw interactions. Large hungry dogs empty the Kong® quickly so they are the most likely to need it topped up.
Left paw (L) Right paw (R)
- Left paw on Kong®, right paw not.
- Left paw over right paw on Kong®.
- Left paw on top of Kong®, right paw underneath.
- Right paw on Kong®, left paw not.
- Right paw over left paw on Kong®.
- Right paw on top of Kong®, left paw underneath.

Interpretation of results:

Once you have recorded 50 interactions of the left or right paw with the Kong® you have sufficient data to determine whether your dog is left-pawed or right-pawed. Dogs that use their left paw 32 times or more are left pawed.

Those that use their right paw 32 times or more are right-pawed. Dogs with less than 32
uses of either paw are considered ambidextrous.

    1. Interesting, isn't it? Our vet actually encourages his clients to do this test with their dogs.
