This answers depends on the size of the dog and the look you want.

Cape Cod Collars are meant for Medium to X Large Dogs.

Generally, we recommend the following:

Medium: Neck 14 to 18"

Large: Neck over 18"

For reference, our labs pictured are 75lbs w/ 22" necks wearing the Large.

We are working on developing a wider collection. To keep it simple we came out with the 3 original colors and will continue to add on. If you have a special request please send us a note and we will see what we can do!

If the collar is too small for your dog please use the spacer provided to increase the length. We create the collar exactly to your measurement. These are custom fit so we can not emphasize how important the measurment piece is. If you are having difficulty please reach out to us.
