Custom Charm Collar
Start with the measurement, not the breed. The notes here are a little guidance; their neck gets the final say.
Included charms are automatically matched to the collar size you buy. Choose their name and colors; we’ll handle the charm fit.
| Size | Neck size | Strap width |
|---|---|---|
| S | 8–12"20–30 cmA starting point for puppies and smaller breeds. | ¾"1.9 cm |
| M | 12–16"30–40 cmA little more room for medium-sized dogs. | ¾"1.9 cm |
| L | 16–20"40–50 cmMore room for medium-to-large and larger dogs. | 1"2.5 cm |
Inch measurements are rounded. Use the centimeter ranges for the closest fit. At 30 cm, choose M; at 40 cm, choose L. Between sizes? Choose the larger size and adjust it to fit.
How to measure
A soft measuring tape.
One reasonably cooperative dog.
Run a soft measuring tape around the part of their neck where their collar rests. Keep the tape flat.
The tape should sit comfortably, without pulling tight. Leave room for three fingers between the tape and their neck, then read the measurement.
Find the range that includes their measurement. Between two sizes? Choose the larger one, then adjust the collar for a comfortable fit.

Extra Charms
Ordering a Custom Charm Collar or Leash? Its included charms are automatically matched. You only need to choose a charm size when buying Extra Charms separately.
Each collar and leash gets its own correctly sized included charms. For extra charms, choose the item they’re going on, then add each size separately.
| Charm size | Fits collars | Fits leashes |
|---|---|---|
| Regular | S and M | Not compatible |
| Large | L | All leashes |
Regular charms fit ¾" straps. Large charms fit 1" straps. S and M collars use Regular charms; L collars and all leashes use Large charms.
Choose extra charms ↗A couple of fit questions
Included charms are matched to each product: Regular for S/M collars, Large for L collars and all leashes.
Charm size follows strap width. S and M collars are ¾" wide and use Regular charms. L collars are 1" wide and use Large charms.
Large charms fit L collars and all leashes. Regular charms fit S and M collars and cannot be used on our leashes.
Breed notes are a starting point. Measure your dog’s neck and use the size chart, because two dogs of the same breed can need different sizes.
THE FIT IS JUST THE START.
