Canny Collar Size Guide
Measure your dog’s neck
Measure your dog's neck snugly, high behind the ears. Do not use your dog's normal collar measurement or add extra space using the two-finger rule.
Measuring your dog's neck takes only a few moments and is the most reliable way to choose the correct size. If the measurement is exactly on the boundary between two sizes, we usually recommend the smaller size.

What if my dog is between Canny Collar sizes?
If your dog's neck measurement falls exactly between two sizes, we usually recommend choosing the smaller size. In our experience, owners often allow a little extra room when measuring, so the smaller size generally provides the better fit.
However, if you have a young, growing dog, you may wish to wait a week or two and choose the next size up.
Should I use the two-finger rule when measuring?
No. Do not add extra space or use the usual two-finger rule when taking your dog's measurement for a Canny Collar. Measure snugly around the neck without adding anything to the measurement. The Canny Collar itself is adjustable to provide the correct fit.
Can I choose a Canny Collar size by breed?
We don't recommend choosing a Canny Collar size based on your dog's breed. Dogs of the same breed can have very different neck measurements depending on their individual size and build.
For example, German Shepherds can require several different Canny Collar sizes. Measuring your dog's actual neck is therefore much more reliable than using a breed-based size guide.
What if I order the wrong size?
Using the guidance above, we're sure you'll get it right first time. But if when your order arrives, you feel that a different size would be better for your dog, we'll exchange it no problem.
Here's our return & refund policy.
What if my dog is too large for a Canny Collar?
The Canny Collar is available in seven sizes for dogs with neck measurements from 23cm to 58cm.
For dogs measuring over 58cm, including many giant breeds, choose the heavier-duty Canny Colossus, available for neck measurements from 58cm to 69cm.
