How To Pick The Correct Collar Size

Step 1. Measure your dog’s neck 

Measure your dog around the top of the neck directly behind the ears. We recommend using a cloth measuring tape.

Step 2. Add 1 to 3 inches to your dog’s neck size 

Generally speaking you should add 1 inch for small dog breeds (less than 10 pounds), 2 inches for medium-sized dogs and 3 inches for larger dog breeds (weighing over 80 pounds).

Step 3. Check the collar size chart below 

Now that you know your dog’s neck size and have added 1 to 3 inches you can check out the collar size chart below. Please keep in mind that we will only offer what we have available to be selected on the site. If you do not see a size from the size chart on the website then we are out of that size. Harness is best fit for smaller dogs. Our collars run a little on the larger size so if you measure and receive the collar and it does not fit we will gladly ship you a return label with the correct size. Please just email us at: 

Important: Our LED Dog Collars are adjustable in size. That’s why the size chart below includes the minimum and the maximum collar length.
