Greyhounds can reach speeds of up to 70 km/h — but when it comes to collar fit, precision matters more than pace. A proper fit isn’t just about comfort. It’s about control, confidence, and everyday ease. As a greyhound mum to Pepper myself, I’ve learned that measuring properly makes all the difference. After all, a collar that fits well is nothing to growl about.
If you’re fitting a martingale collar, getting the measurements right ensures the collar sits securely without slipping or tightening excessively. Sighthounds have beautifully slender heads and necks. That elegance requires a slightly different approach.
Why Fit Matters
Greyhounds, whippets and Italian greyhounds have necks that are often wider than their heads. This means standard collars can slip off easily. A properly fitted martingale provides gentle control by evenly distributing pressure when tension is applied.
According to the RSPCA Australia, collars should fit snugly but comfortably, allowing you to slip two fingers between the collar and your dog’s neck. That small detail matters. Too loose and it may slip. Too tight and it can cause discomfort during walks.
The goal is balance. Secure. Comfortable. Reliable.
What You’ll Need
- A soft measuring tape (fabric tape measure is ideal)
- Your dog standing calmly
- A treat or two for cooperation!
If you don’t have a soft tape, use a piece of string and measure it against a ruler afterwards. Simple and effective.
Step-by-Step Measuring
1. Measure the Neck
Wrap the tape measure around the middle of your dog’s neck — this is typically where the collar will sit. For sighthounds, this is slightly higher than you might expect, closer to the narrowest part of the neck just behind the ears.
Ensure the tape is firm but not tight. You should comfortably fit two fingers underneath. Record this measurement in centimetres.
2. Measure the Widest Point of the Head
This step is essential for sighthounds. Measure around the widest part of your dog’s head, usually just in front of the ears. The collar must be able to slip over the head when fully loosened.
If the head measurement is larger than the neck measurement, always consider both when selecting your size.
3. Compare With Size Guide
Once you have both measurements, compare them with the sizing chart on the specific collection page:
If your dog’s measurement falls between sizes, we generally suggest choosing the size that accommodates the head measurement while still adjusting securely to the neck.
Breed Considerations
Greyhounds typically live between 10–14 years. Whippets often share a similar lifespan, while Italian greyhounds may live slightly longer, around 12–15 years. Each breed has its own structure and sensitivities.
Sighthounds are known for their lean build and fine skin. Some may be prone to sensitivities such as dental issues or joint stiffness as they age, and their delicate neck structure means a wide, well-fitted collar offers better comfort during daily walks.

Final Check
After fitting the collar, gently tighten it as it would sit during a walk. The two metal slides should come close together but not touch completely. When relaxed, the collar should sit comfortably without sagging too low on the neck.
Take a short walk indoors first. Observe how it moves. Make small adjustments if needed.
Measuring properly takes just a few minutes. The payoff? Peace of mind every time you clip on the lead. And as any devoted pet parent knows, that confidence is worth it.
