How to Measure Your Pup to Determine Sizing


  1. Measure the widest area of the base of the neck of your pup
  2. Measure the widest area of the ribcage behind the front legs of your pup.
  3. Review the product size guides below to determine what size would the best fit.

Please ensure that you measure your pup's neck and chest for the most accurate fit, as our sizing may be different than other brands' sizing.
It is recommended that you double check your pup's measurements prior to placing an order. 

It is recommended to allow for 2 fingers to slip in between the neck and the chest measurements so that your pup has a snug, yet not too tight, fit.

If your pup's measurements fall between sizes, we recommend ordering the larger size.

If you require assistance with sizing or are unsure of what size to order, please email us at
