Measuring for your dog for a collar:
- Ensure your dog is standing still
- Measure using a fabric tape measure or string
- Measure the neck line at the base of the neck
- You should then be able to fit 1 to 2 fingers inside the collar, for your dog to be comfortable
| To Fit Dog's Neck Size | Collar Width | Collar Strength | |
| XS | 23-29cm / 9-11.5in | 1.5 cm / 0.6 in | 70kg |
| S | 28-42cm / 11-16.5in | 1.5 cm / 0.6 in | 119kg |
| M | 41-52cm / 16.5-21in | 2.0 cm / 0.8 in | 224kg |
| L | 50-62cm / 20-24.5in | 2.5 cm / 1.0 in | 287kg |
| XL | 60-89cm / 24-35in | 3.5cm / 1.4 in | 287kg |
Note: If your dog's neck size overlaps two sizes, then unless you expect your dog to continue growing, the smaller of the two sizes is the better choice for your dog.
