Wide Collars Size Guide
Wide Collars
Measure snugly around the middle of your dog's neck with a tape measure, without leaving any extra space. Our collars are true to size, so a snug measurement will ensure the best fit.
Collar Sizing Explained: Each collar size reflects its inner circumference range. For example, a size S (27-32 cm) means the collar’s inner circumference fits necks measured between 27-32 cm. Based on this, you can decide whether you want a looser or tighter fit, as the inner circumference of the collar corresponds to your pet’s neck size.

| Size | Neck Circumference (cm) | Neck Circumference (inches) |
|---|---|---|
| XXS | 17 - 22 | 6.7 - 8.7 |
| XS | 22 - 27 | 8.7 - 10.6 |
| S | 27 - 32 | 10.6 - 12.6 |
| M | 32 - 37 | 12.6 - 14.6 |
| L | 37 - 42 | 14.6 - 16.5 |
| XL | 42 - 47 | 16.5 - 18.5 |
For larger breeds, we have designed a slightly different collar width ratio for L and XL sizes to ensure more security and comfort.
| Size | Collar Width Ratio (cm) | Collar Width Ratio (inches) |
|---|---|---|
| XXS | 1.5 : 4.5 | 0.59 : 1.77 |
| XS | 1.5 : 4.5 | 0.59 : 1.77 |
| S | 1.5 : 4.5 | 0.59 : 1.77 |
| M | 1.5 : 4.5 | 0.59 : 1.77 |
| L | 3 : 4.5 | 1.18 : 1.77 |
| XL | 3 : 4.5 | 1.18 : 1.77 |
