Sighthound collars need a wider strap (38 to 43mm across the range) to distribute pressure across a long thin neck, plus tapered or rounded edges for comfort. Wool over a BioThane strap gives breathability and natural feel with a strap that wipes clean. Leather gives the classic look and ages beautifully. BioThane gives waterproof durability for active sighthounds. The Green Dog range covers all three.
Sighthound owners come to the workshop with a specific set of concerns. Standard collars slip over the head, the neck shape is unusual, the dog is sensitive to pressure, and the breed-specific aesthetic matters. The universal answer to most of these is a wider strap with sighthound-specific cut.
What follows is the three sighthound collar options I make in different materials, what each is best for, and how to choose between them.
Why Sighthounds Need a Different Collar
Sighthounds have a head that is narrower than the neck, which is the opposite of most other breeds. A standard collar fitted to the narrowest point of the neck can slip forward and over the head if the dog backs up suddenly or panics. The traditional answer is either a martingale-style collar that tightens slightly under pull, or a wider sighthound-cut collar that simply does not have that slip risk because the strap is too wide to fit over the head.
The wider strap also matters for comfort. A long thin neck has less muscle and more sensitivity than a thick-necked breed. A 38 to 43mm sighthound cut distributes pressure across more of the neck. A narrow everyday strap on a whippet concentrates pressure on a narrow band and tends to mark the coat.
Wool: The Custom Brampton and Custom Dingley Sighthound Weave
The wool sighthound collars are the lightest of the three. The Custom Brampton Hybrid and the Custom Dingley Hybrid use a four-row 43mm wool weave over a 19mm BioThane strap, in charcoal grey Brampton wool or ecru Dingley wool. Choose the four-row sighthound weave rather than the three-row at 34mm. The wool breathes and takes the natural patina of use, and the strap underneath wipes clean.
I designed these as part of the Sheep Shed range for sighthounds whose owners wanted a natural fibre sitting against the dog. The wool weave is hand-bound, and the buckle, D-ring and rivet finish are yours to choose. There are also two fixed colourways if you would rather not specify anything: the Brampton in beige and the Dingley in hunter green.
The wool-on-leather version of these collars is no longer made for this site. Those have been rehomed to Daylesford and redesigned specifically for Daylesford, in Mini, Classic and Sighthound widths, in cream or grey undyed British wool with brass hardware, carrying no tassel and no Green Dog brass disc. There is a note on the Daylesford page. So when this article compares wool against leather, the wool collar you can buy here is the wool-over-BioThane hybrid, and the leather option is the Cotswold Heritage below.
Leather: The Cotswold Heritage Sighthound Range
Leather is the classic sighthound material, and the Cotswold Heritage Leather Sighthound Collar is the workshop's leather option. Vegetable-tanned cowhide, Italian, French and British, chosen for each piece rather than a single origin claim, with an edge-burnished finish, hand-set solid nickel or solid brass hardware, and a tapered profile cut specifically for the sighthound neck shape.
Leather suits sighthounds that mostly walk on dry routes and live as house dogs. It is not the right material for a sighthound that swims or works in the rain regularly, where the leather softens and stretches. For most pet sighthounds it is the most aesthetically traditional and one of the longest-lasting options.
BioThane: The Cotswold Rambler
The Cotswold Rambler is the BioThane sighthound collar. Polyurethane-coated polyester webbing, fully customisable, with the hardware finish of your choice. It is the choice for active sighthounds that swim, run agility, do trail work, or live in muddy rural conditions where leather and wool both struggle.
The same Rambler shape is also available in collaboration editions with Life Like Charlie (the Monkey Blue, Nala Green, Nala's Tribe, and Space Monkey colourways), all on the same sighthound-cut base.
How to Choose Between the Three
| Material | Best for | Trade-off |
|---|---|---|
| Wool over BioThane (Brampton or Dingley) | Indoor and dry-walk sighthounds, sensitive skin, natural fibre preference | The strap wipes clean, but the wool is untreated and should not be soaked |
| Leather (Cotswold Heritage) | Pet sighthounds, traditional aesthetic, long lifespan | Avoid for swimming and working dogs |
| BioThane (Cotswold Rambler) | Active and outdoor sighthounds, swimming, mud, all-weather use | Less natural feel; visible synthetic finish |
The full sighthound collar collection covers all three materials. The measuring guide covers fitting for sighthound necks specifically. For more on whippet-specific fit, see the whippet collar fit guide.
Frequently asked questions
What is the best collar for a whippet?
The best collar for a whippet is a sighthound-specific design with a wider strap (38 to 43mm across the range) to distribute pressure across the long thin neck. The Custom Brampton Hybrid in its four-row sighthound weave (wool over BioThane), the Cotswold Heritage Leather Sighthound, and the Cotswold Rambler BioThane are the three Green Dog options, each suiting a different lifestyle and aesthetic.
Why do sighthounds need wider collars?
Sighthounds have long thin necks and small heads, which means a standard everyday collar can slip over the head and concentrates pressure across a narrow band of neck. A wider sighthound cut, 38 to 43mm across the range, distributes pressure evenly and reduces the slip risk.
Are martingale collars better for sighthounds?
Martingales tighten under pull but stop short of choking, which is useful for sighthounds prone to slipping standard collars. They are not the only option. A properly fitted wide-strap sighthound collar with the right closure can work equally well, especially for sighthounds that are not slip risks. The half-check BioThane in the Green Dog range is a martingale-style alternative.
What collar fits an Italian greyhound?
Italian greyhounds need a sighthound-cut collar in their size range, typically with a narrower cut than a whippet collar. The Cotswold Heritage Leather Sighthound and the Custom Brampton Hybrid both come in sizes that fit Italian greyhounds.
How do I measure my sighthound for a collar?
Run a soft tape around the top of the neck, just behind the ears and under the chin, snug but not tight. A sighthound collar sits higher on the neck than an ordinary collar, because the neck is wider than the head and a collar measured further down can pull off over the ears. Do not add anything to the measurement. Sighthounds vary widely in neck size between breeds and individuals, so measure the specific dog rather than rely on a breed average. The Green Dog measuring guide covers the full process.
