The sizing of each collar is adjustable within a certain range.

To make it easier for you to decide what size to purchase, we’ve listed the neck sizes that each size fits. So if your dog has a 40cm neck circumference, you would purchase either a Small or Medium collar (we’d recommend Medium).

X-Small 28cm – 38cm 41cm 2cm
Small 34cm – 41cm 44cm 2.5cm
Medium 37cm – 46cm 50cm 2.5cm
Large 41cm – 52cm 56cm 2.5cm
X-Large 42cm – 56cm 60cm 2.5cm
