Measuring Guide

There are a couple of different ways to work out what size collar you should order:


The easiest way is to measure your Furbabies current collar, lay it out flat and measure from where the Biothane starts at the buckle to the hole you are currenly using.

If your pets collar has a side release buckle it's slightly different - please refer to the below example:

You may also take a measurement directly from your dog's neck. Simply wrap a soft measuring tape around the point of your dogs neck that you wish the collar to sit, pull it as firmly as you would like the collar to fit and that will be your measurement!

Don't have a measuring tape? Print out our Digital Measuring Tape instead!

Please note, when ordering there is the option to type your pet's neck measurement in, this is HIGHLY RECCOMMENDED as we can place custom holes in your collar for a better fit!

If you don't have a tape measure you can use a piece of string to wrap around the neck, lay it out flat, and measure with a ruler.

*Please note this is simply a guide and it is HIGHLY RECOMMENDED to take measurements of your dog for your sizing rather than selecting based off the breeds below*

XX-Small 5/8" (16mm) Chihuahua, Miniature Pinscher. 
X-Small 5/8" (16mm) Chihuahua, Miniature Pinscher, Pomeranian, Miniature Dachshund.
Small 3/4" (19mm) Lakeland Terrier, Maltese, Beagle, Pug.
Medium 1" (25mm) Border Collie, Australia Shepherd, Kelpie, Koolie, French Bulldog.
 Large 1" (25mm) & 1½" (38mm) Labrador, Golden Retriever, Staffordshire Bull Terrier, German Shepherd, Bernese Mountain Dog
X-Large 1" (25mm) & 1½" (38mm) Great Dane, Tibetan Mastiff, Newfoundland.


Measuring for slip collars and martingales are slightly different as we need two (2) measurements from you!

The first measurement is the neck measurement, please measure firmly around your dogs neck in the place you would like your collar to sit.

The second measurement is the widest point of your dogs head, generally in front, behind, or over your dogs ears - please refer to the below photo as an example.
