BLOCKY DOGS ® Collars have four sets of holes. It is recommend that dogs wear their collars on one of the middle sets of holes to leave room for weight fluctuations up or down. Even adult dogs experience weight fluxes from time to time. Typically, dogs wear their BLOCKY DOGS ®collars on the hole 2" larger than their actual neck measurement. Collars are listed by largest size and have four adjustments. Example: a 24" collar is 24" on the last/largest hole setting; 23" and 22" on the middle holes; and 21" on the smallest hole setting. By following these measuring guidelines, you can choose how you want your BLOCKY DOGS ® collar to fit whether it’s a growing puppy who needs room for growth or an adult who is finished growing.

The above photo shows how to measure, using one of my own American Bulldogs, AuRoara-Blaze. Click on it to get a larger view. The photo shows how her neck was measured. I used a tape measure and measured around her neck in the middle. You can see that her neck measures 21”. Adding 4” gives me 25” which you can see in the next photo is what size collar I made for her.

AuRoara wears her collar on the 23” hole (2” larger than her actual neck measurement).
