FitPAWS Sizing Guidelines
Choosing the correct size ball for your dog depends on what type of exercises your dog will be doing on the ball and the size of your dog.
For weight bearing activities (when a dog is standing partially on the ground and partially on the ball), choose a ball that is slightly under your dog's withers (or the highest part of the shoulders where the neck meets the back).
For core strengthening activities (when a dog is sitting, standing or lying on the ball), choose a ball that is at least 4" taller than your dog's withers.
If you need a ball smaller than 40 cm, purchase the 40 cm ball and decrease the amount of air that you pump in so that the ball is shorter.
The FitPAWS Peanut is a good choice for beginners and for weight-bearing exercises as the unique shape of the peanut provides an easier balance challenge and rolls in one direction or plane at a time.

The FitPAWS Egg is a better choice for more advanced
core strengthening exercises as it is more unstable than
the peanut and rolls in multiple directions or planes.
You can always use a large ball for a small dog, but not a small ball for a large dog. If you have more than one dog, choose a size that fits your largest dog. You may find it more comfortable for your own back to work with your dog on a larger/taller ball. Using a larger ball for a small dog also has the added benefit of providing more surface area to work on. The FitPAWS Peanut is naturally longer than the FitPAWS egg and provides more of an elongated surface training area.
