Dog Collar Size Chart

American Pack dog collars come in three sizes, small, medium, and large. To get the best fit, please measure your dog’s neck where the collar will rest and use that measurement to determine the appropriate optimal size. If your pup’s still growing, you may want to pick a size based on maximum adjustment size and let your pup grow into it.  

For a proper fit, measure your dog's neck with a cloth seamstress tape measure.  Pull the tape snug but not tight. (If you do not have a tape measure, you can use a piece of string and then measure the string with a rigid ruler.)  When the collar is on his neck it should allow you to slide two fingers under a properly fitting collar and your dog's neck. If there's extra room, you need a smaller size. If both fingers don't fit, the collar is too small.

A collar shouldn't be tight around your dog's neck and therefore it will not be the exact measurement of your dog's neck. For safety reasons - so it doesn't snag on something, it shouldn't be too loose either. A snug fit is what you are aiming for and not a tight one or one that chokes.
