Size charts

Each collar type has its own size chart. Our sizes are unique to our brand. size chartThis chart is meant to be a guide only.

Width Guidelines

  • 3/8" for toy breeds, under 10 lbs
  • 5/8" for small breeds, 10-30 lbs
  • 3/4" for medium breeds, 20-50 lbs
  • 1" for large breeds, 40-100 lbs
  • 1.5" for giant breeds, 100+ lbs

Measuring for a dog collar


Sizing Inconsistencies: We are in the process of modifying all of our collar size ranges and size labels (S, M, L) to be more congruent across styles. You may see inconsistencies between our size chart, descriptions, and available selections while we do this. If in doubt, choose the appropriate length shown (8-13, 14-22, etc) regardless of size label (S, M, L, etc). 

As always, Fox Valley Pet Wear will custom-size your gear to fit your pet for no extra charge! All you need to do is provide measurements with your order.**

** if your measurement and request-details align with one of our standard sizes, we may provide the standard size. We will use our professional opinion or reach out to you with questions.

One more thing about custom sizing...

Keep in mind we cannot add range to one end without sacrificing range from the other. Expect roughly 3" of range for small sizes, 5" for medium sizes, 7" for large sizes, and so on.

Choose-a-Fabric 3/8" BreakAway Adjustable Dog Collar is perfect for the smallest of dogs! This collar is recommended for SMALL dogs only. Clasp opens with just 5lbs of pressure, which is ideal for dogs less than 10lbs.

Adjustable collar features a unique plastic breakaway clasp that will come loose if your pet gets caught on something (fence, crate, heat vents, another dog, etc). Double D rings allow you to safely use this collar with a leash (although it is not recommended for unsupervised tie-outs).

For collars over 13" only: Fox Valley Pet Wear breakaway collars come with a proprietary buckle reinforcement to prevent accidental breakaways more common with larger or heavier dogs. Buckle reinforcements are removable, replaceable, and adjustable - instructions are included with purchase.

Choosing a Fabric

** Note: the collars shown in the photos on this page are construction examples only. Some or all of these fabrics may be sold out. Please choose your fabric print from our current available prints as explained below

⚠️SPECIAL NOTE⚠️ Since this is a 3/8" wide item, some of our fabric prints are too large to fit their images on such a narrow collar. We strongly recommend choosing small, repeating patterns for 3/8" collars to be sure the pattern is visible on the final product. Keep in mind that nearly all of our listings photos are of 1" wide collars. If you need help/recommendations, feel free to send us a message.

Choose your fabric choice(s) using the three "FABRIC CHOICES" photos. Type the names in the Fabric choices boxes. Thumbnail pictures are NOT to scale - to get a sense of how the fabric looks on a collar, use the search bar in our shop to search for the fabric name. Not all of our fabrics can be found this way, but most will be. ⚠️ Please include 1st and 2nd fabric choices in case of low quantities. Fabric prints may sell out without notice.


All Roka Pet Wear items have a lightweight (but STRONG) 2000lb-rated webbing core and triple reinforced seams. Each item includes premium nickel plated steel slides and D-rings.

 Size & Width

Measure your dog's neck or collar per the photo. Choose appropriate size range & width. **Listed size ranges may vary up to 1/2".

If your dog falls between sizes OR is a growing puppy, please measure their neck or a current collar and include your measurement with your order. We will custom-size your collar, free of charge. Custom-sized collars will be adjustable in either direction, or in the case of a puppy, will only adjust upwards to allow the most room for growth.

Tag Ring

A D-ring sewn in at the adjustment slide just for hanging tags! Also frees up space on your main D-rings for your leash!
