To find the right size collar, you will need to take 2 measurements.</br>The size in inches around their neck circumference.</br>The size in inches from the neck to the snout.</br>2. The second measurement (neck to snout) is the most critical, as the collar needs to extend beyond the nose in order to provide effective protection. If your dog or cat's nose is sticking out of the end of the cone, they may be able to reach the affected areas.</br>3. If any of the measurements are 'between' two sizes, choose the larger size. If your measurements are toward the upper end of the range given for a particular size, you may also want to choose the larger size, as you may also wish to do for heavily coated dogs to accommodate all that fur.<p><p><b>Package includes: 1 x Pet Recovery Cone E-Collar.</b></p><p><b>Note:</b></br>1.
