Choosing the right size dog 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.

Step 1:  Measure your Dogs Neck and Head

Measure Dog's Neck SizeHave your dog sit in front of you and 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:  Choosing the Right Sized Collar

For martingale type collars take the neck and head sizesfrom 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 see if it fits within one of our standard size ranges.  

TIP: If the range crosses our standard sizes (ex. X-Small, Small, Medium or Large) then you will need to select "Custom Size" and enter the size needed.  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.
