All dogs are different and vary in their size, just as people vary in size and
shape. Here is a general guideline to fit your dog appropriately for a dog collar.
For a proper fit, measure your dog's neck with a cloth seamstress's tape measure.
Take a measurement a few inches down from his head and then add an inch for
very small dogs or two inches for medium and large dogs. (#1)
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.)
Allow sufficient room to slip two fingers between the collar and the dog's
neck. Or you can measure his neck and add two inches.
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.
If ordering a Martingale
or a Tag collar
, be sure to also measure at point #2 in the
image above to make sure the size you select fits within the range of these two
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. Always monitor your furry
little friend while he or she is on their leash with a collar, so they don't
get caught on a fence or other environmental object that would cause furry friend
