Sizing instructions for Glowdoggie LED dog collars, lighted dog collars

Finding the right size for your doggie.

Measuring your Glowdoggie size:
(If you don’t have a soft measuring tape)

1.) Using the end of your leash or a belt, make a snug loop around the widest part of your dog’s head. Make sure it’s not too loose - just enough so that you can slide the loop over the head and back off again over the dog’s ears without discomfort. 

You can also use your dog’s collar: loosen it just enough so it slides over the dog’s head and back off again without being uncomfortably tight over the ears.


2.) Hold that spot on the leash (or belt) and measure its length with a tape measure. If you use a collar, then open the collar and measure the length (taking into consideration the part of the collar that overlaps to connect).
This is the circumference of your dog’s head in inches. 
If you measure close to 1 inch over a Glowdoggie size, for instance 18.6”, then choose the Glowdoggie size down - so in this case an 18” collar. The circular shape of the regular Glowdoggie™ allows for a little tolerance, and we can provide you with an intermediate size solution if necessary.

(Please note that the Mini Glowdoggie does not show such a tolerance, so choose the next size up, rather than down if you measure over a Mini Glowdoggie size.)

In this particular example we’ve measured close to 19”, which is normal for most female and smaller male Labradors or Golden Retriever sized dogs. In this case we would recommend an 18” collar. (Big males, or labs with a thicker body/neck, will likely need a 20”, for example).

Choosing the right size BEFORE you order your Glowdoggie™ is essential so please follow the instructions below or contact us for help.

The Glowdoggie™ is an LED safety ring which has to slide over the dog’s head in one piece, similar to a bangle bracelet. What’s important is therefore not the neck or collar size, but the circumference of the widest part of the dog’s head, in front of the dog’s ears.

Of course, if your dog has a particularly large neck (and small head) the ring will have to sit comfortably on the neck too, so keep this in mind when measuring.

The Glowdoggie comes with a nylon strap that can be clipped-on to the dog’s existing collar or harness to make sure the product doesn’t slip off in the woods or whilst swimming. Nonetheless, we always recommend taking the time for a accurate measurement of your dog’s head.

The Glowdoggie is divided into two primary ranges:

-The MINI Glowdoggie: for small dogs, and very narrow-headed dogs, with head sizes of between 10” and 13” maximum. (There is no upwards tolerance on the Mini range, so your dog’s head must be under the Glowdoggie size for it to fit comfortably.)

- The Standard Glowdoggie: this includes the Glowdoggie Classic, Classic+, and Ultra models. The standard range is for dogs with a head circumference upwards of 13.1”, all the way up to 29” (if your dog is the size of a small pony ;-))
