Choosing the right size collar for your dog

These dog collars can be ordered with custom sizing to fit your dog's specific neck size. View them now! There are currently no industry standards for dog collar sizes or even standards for how to measure your dogs neck. Therefore, please review these details for how If It Barks handles sizing.

striped collars

Ultra thin (.04"), lightweight and strong webbing with three layers of colored ribbon.

reflective collars

Be safe and be seen at night with our reflective collars made with durable 3M reflective material.

webbing collars

Comfortable colored webbing (.075") in bold, stylish colors. Simple and classic style.

hemp collars

Natural hemp collars are comfortable from the start and get better and softer with age.

Step 1

Measure your pup

Have your dog sit in front of you. Using a soft tape measure or piece of string* do the following:

Head Size: From the top of the dog’s throat, over the ears to top of head (this is the size of the actual head).

Neck Size: Loosely measure the neck where the collar would normally sit sliding two fingers between the dog's neck and measuring tape. Adding the two fingers should make the collar size about 2" larger than the dog's neck size (maybe closer to 1" on very small dogs.)

Step 2

Choose the right size

For martingale type collars take the neck and head sizes from Step 1. Order a collar that will fall within this range of measurements. If you order a martingale collar with a buckle then only the neck size is important.

For side release buckle type collars take the neck size and order a collar at that neck size.

TIP: If It Barks offers custom sizes in our popular Martingale Collars and standard Side Release Dog Collars to ensure your dog get's the most perfect fit.
