This guide should help on how to accurately measure to make sure you get a great fit.
Caninedesign's default sizes are 11-14", 13-19", 15-22", and 18-26". That doesn't mean you HAVE to choose one of those ranges. You are more than welcome to type the actual neck size in the checkout notes, or send us an email with your measurement. We'll make a custom range around your dog's size.
How to Measure Your Dog
The best way to measure your dog's neck size is to use tailor's tape. Wrap it around the base of the neck where the collar sits. Adjust the tape to however tight (or loose) you want the collar. All Caninedesign collars are adjustable, so the measurement doesn't have to be exact.
There's no need to make adjustments for martingale collars or padded collars. Use the dog's actual neck size to order a collar.
If you don't have tailor's tape, you can use string, rope, thread, twine, or whatever else you have around the house. Mark the string, lay it flat, then measure with a ruler.
Measure the Current Collar
Another way to find your dog's neck size is to measure the current collar. This is easy with quick release buckle collars. Lay it flat and measure the length of the collar, not including the male prongs.
The inside circumference of the collar will be your dog's neck size. Measure the diameter and multiply by Pi. Round up to the nearest inch or half inch.
Buying Gifts
This question pops up quite a bit around the holidays, "I'm buying a collar as a gift. How do I know what my friend's dog's neck size is?" Unfortunately the only way to know is to measure. Even if you know the breed and approximate weight, neck sizes still vary greatly from dog to dog, even within the same litter. We recommend purchasing one of the pre-made collars, which are returnable, or buying a gift certificate.
