A simple guide to help you choose the perfect fit for your dog.
How to Measure
Use a soft tape measure and measure:
Neck — around the base of the neck where the collar naturally sits
Chest — widest part of the ribcage (for bandanas or harnesses)
Length — base of neck to start of tail (for clothing)
If your dog is between sizes, choose the larger size for comfort.
Collar Sizes
Our collar sizes are measured from the first hole to the last hole.
This gives you the true usable size range of the collar, so you can match it accurately to your dog’s neck measurement. We recommend measuring your old collar from the start of the material to the hole that they use.
Example
If a collar is listed as 20–30 cm, that means:
• 20 cm = the first (smallest) hole
• 30 cm = the last (largest) hole
Your dog’s neck measurement should sit somewhere within this range for the best fit.
Extra small 20-30cm
Small 24-34cm
Medium 30-45cm
Large 42-57cm
All collars are fully adjustable for a comfortable, secure fit.
Collar Widths
We offer two premium widths to suit different breeds and preferences:
20mm Width
Ideal for small to medium dogs.
Lightweight, comfortable, and perfect for everyday wear.
25mm Width
Best for medium to large dogs.
A sturdier, chunkier feel while still soft and comfortable.
Lead Length
Standard Lead — 1.5 metres
Perfect for everyday walks and giving your dog a little freedom while staying close.
