What size Canny Collar?
Measure your dog’s neck
To ensure your Canny Collar fits accurately and is safe to use when walking your dog, take a tape and measure around your dog's neck snugly, to just behind the ears. Then, choose the correct size Canny Collar for your dog using the following measurements.

If your dog's neck measurement falls exactly between two sizes, our experience shows that the best option is normally to choose the smaller of the two sizes to ensure a good fit.
