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.

Great Collar

We are so happy with the quality and workmanship on our new break away collar for our small dog. The collar came just as we ordered and it looks great. Thank you again Diana for a great product and making sure it had the extra upgrade tag ring.

Robin Gordils
Best breakaway collars

I've used these collars on 6 to 96 pound dogs. They last forever, look great and best of all break if the dog gets hung up.

Cate Crenshaw
Great collars

I’ve had a tough time finding a breakaway collar that wasn’t extremely hard to break. These are it. Some resistance, but safely easy for a small dog to get out of. Great product! Thank you.
