How to Measure Your Dog’s Neck for a Collar

Measuring your dog’s neck to size for a dog collar is actually quite simple and can be done in two different ways. Plus, the good news is that you likely have everything you need somewhere in your home. You’ll need either measuring tape or a piece of string and a tape measure (or ruler) to measure your dog’s unique and proper size. Depending on the materials you have, follow the appropriate instructions below. Tip: Dog collars sit high up on the neck, so be sure you are measuring where a collar would typically sit on your dog. 

The Measuring Tape Method

Measuring your dog’s neck with measuring or sewing tape is simple. With your dog sitting near you, loosely measure the neck where the collar would normally sit. You want to keep the tape snug, but you also want to be able to slide two fingers between the dog’s neck and measuring tape. Adding two fingers should make the collar about two inches larger than your dog’s neck size. Once you have the measurement you can remove the measuring tape from your dog’s neck.


The String Method

If you don’t have measuring tape, you can still accurately measure the size of your dog’s neck with a piece of string. Similar to the measuring tape, you’ll loosely wrap the string around your dog’s neck where a collar would normally sit. The string should be snug enough that you can fit two fingers between it and your dog’s neck. Let go of one end of the string and mark the spot x that met the end with your finger. From there, remove the string completely and use a tape measure or ruler to find the exact length.

Once you have the right measurement, you can confidently shop for a dog collar.
