Find the perfect fit for your dog in seconds. Select your breed and enter measurements for instant recommendations across every Snazzy Pooch product.
Measure around the base of the neck where a collar sits. Keep two fingers under the tape for a comfortable fit.
Measure the widest part of the chest behind the front legs. Most important measurement for harnesses.
Use accurate scales. Weight guides No-Pull and Step-In sizing. If between sizes, always size up.
| Size | Strap width | Neck measurement |
|---|---|---|
| XS | 13 mm (0.5") | 15 – 28 cm |
| S | 20 mm (0.79") | 20 – 29 cm |
| M | 20 mm (0.79") | 27 – 41 cm |
| L | 25 mm (0.95") | 33 – 52 cm |
| XL | 25 mm (0.95") | 37 – 60 cm |
Tip: Between sizes? Choose the smaller size for collars — always measure your dog's neck directly, not an existing collar.
| Size | Width | Neck | Chest |
|---|---|---|---|
| XS | 13 mm | 15 – 28 cm | 20 – 32 cm |
| S | 20 mm | 19 – 29 cm | 22 – 35 cm |
| M | 20 mm | 27 – 41 cm | 31 – 59 cm |
| L | 25 mm | 35 – 55 cm | 40 – 75 cm |
| XL | 25 mm | 42 – 70 cm | 49 – 90 cm |
Tip: Chest girth is the most important harness measurement. If between sizes, always size up.
| Size | Weight | Neck | Chest |
|---|---|---|---|
| XS | 2 – 4 kg | 22 – 34 cm | 34 – 40 cm |
| S | 4 – 8 kg | 32 – 48 cm | 44 – 52 cm |
| M | 8 – 12 kg | 40 – 60 cm | 48 – 62 cm |
| L | 12 – 20 kg | 44 – 66 cm | 59 – 76 cm |
| XL | 20+ kg | 52 – 76 cm | 74 – 102 cm |
Tip: No-pull harnesses sized primarily by weight. Ideal for Labradors, Beagles and high-energy breeds.
| Size | Webbing width | Chest girth |
|---|---|---|
| S | 1.5 cm | 35 – 50 cm |
| M | 2 cm | 45 – 68 cm |
| L | 2.5 cm | 55 – 78 cm |
Tip: Ideal for dogs who dislike things going over their head. Particularly good for Dachshunds — keeps pressure off the spine.
| Size | Width | Length |
|---|---|---|
| S | 13 mm (0.5") | 120 cm (47.25") |
| M | 20 mm (0.79") | 120 cm (47.25") |
| L | 25 mm (0.98") | 150 cm (59.06") |
Tip: Match your lead size to your collar or harness for the best proportion and a perfectly coordinated matching set.
| Size | Dimensions | Best for |
|---|---|---|
| S | 7.5 cm × 5 cm | XS & S collars |
| M | 10 cm × 6 cm | S & M collars |
| L | 11.5 cm × 6 cm | M & L collars |
Tip: Bows attach directly to the collar. Choose the size that matches your collar for the best proportion. Perfect for weddings.
Broad chest and powerful shoulders. Many Labs fill out until 18–24 months. No-Pull or padded harnesses recommended. Check chest room over winter coats.
Muscular neck and deep chest. Choose sturdy, padded harnesses and avoid rubbing under the forelegs. If between sizes on chest, always go up.
Stocky frame with short neck. Avoid pressure on the throat — a Comfort Fit harness spreads load across the chest. Watch chest width carefully.
Long backs and narrower fronts. Step-In harnesses keep pressure off the spine. Ensure the chest strap sits lower and does not rub the underarm.
Fluff can hide fit — re-measure after grooming. Adjustable Step-In or No-Pull harnesses suit energetic walks. Full grown by 12–18 months.
Feathered coats need adjustability. No-Pull or Comfort Fit ideal for adolescence when pulling is common. Check fit seasonally.
Active scent hounds — choose secure Step-In or Comfort Fit. Measure snug to prevent backing out when following a scent.
High-energy escape artists. A snug Step-In or No-Pull harness helps control zig-zagging. Double-check chest fit regularly.
Small frames need light hardware and soft webbing. Avoid bulky fittings near joints. Step-In harnesses are safest for Chihuahuas.
Athletic working builds. Front-clip options assist with heel training. Coats change seasonally — re-check fit every few months.
Measure the neck just above the front shoulder blades below where a collar sits, and the widest part of the chest behind the front legs. Keep the tape snug but not tight — you should be able to fit two fingers underneath. The chest measurement is the most important for harness sizing.
Match your dog's neck measurement to our collar size ranges. If between sizes, choose the larger for comfort. Always measure your dog's neck directly rather than measuring an existing collar — collars stretch over time and will not be accurate.
Yes. The Control of Dogs Order 1992 requires a collar with the owner's name and address when in a public place. Our personalised engraved collars satisfy this requirement — your dog's name and your contact details are engraved directly onto the collar, so no separate tag is needed.
Active pullers benefit from a front-clip No-Pull harness. Smaller breeds and dogs who dislike things over their head often prefer Step-In styles. Dachshunds should always use a Step-In or chest harness to protect their long spine. Use the interactive tool above for a tailored recommendation.
For harnesses, always size up — a slightly larger harness can be adjusted snugly, while a too-small harness cannot be adjusted at all and can cause discomfort. For collars, choose the smaller size if your measurement is near the bottom of the larger size's range, as collars should fit snugly.
Yes — every collar and harness can be personalised with your dog's name, your phone number or postcode, your choice of font, and hardware colour. Each piece is made to order specifically for your dog.
Select "Other breed" and enter your dog's actual measurements — neck, chest and weight — for accurate sizing. If you're unsure, contact us and we'll help you find the right fit.
Our size guide covers the most popular dog breeds in the UK. Whether you're looking for a personalised harness for a Cavapoo, the right collar size for a French Bulldog, or a no-pull harness for a Labrador, our interactive tool gives you instant recommendations based on your dog's actual measurements.
If your measurement sits at the very end of a size range, size up for harnesses and choose the smaller band for collars. Always check chest room for deep-chested or stocky breeds like Staffies and French Bulldogs.
Rubbing near the forelegs? Lower the chest strap or try a Step-In. Collar rotating or slipping? Adjust smaller or try a narrower strap width. Pulling on walks? A front-clip No-Pull harness can significantly help with heel training.
