Dog Collar Size Guide: How to Measure for the Right Fit

Wrap a soft measuring tape around the base of your dog's neck, where the collar naturally sits — slightly above the shoulders, not up near the ears. Keep two fingers flat between the tape and the neck so the result is snug but never tight, then read the measurement in inches. No cloth tape? Wrap a string, mark where it meets, and measure the string against a ruler.

That single neck measurement is all you need to choose a collar size below. If your dog is still growing, measure again before ordering rather than guessing a future size.

Match your dog's neck measurement to a size. Width is ¾″ on XS–S and 1″ on M–XL. If you fall between two sizes, size up — every Amu collar adjusts down to a smaller setting.

Small breeds (Chihuahuas, Yorkies, Dachshunds) usually land in XS–S; mid-size dogs (Beagles, Border Collies, Cockers) in M; and larger dogs (Labradors, Golden Retrievers, German Shepherds) in L–XL. Breed is only a starting point — always trust the tape over the breed.

Two widths: ¾″ for smaller dogs and everyday walks, 1″ for larger or stronger pullers.

• ¾″ width — 6 ft length
• 1″ width — 6 ft length

Match the leash width to the collar weight: a ¾″ collar pairs with the ¾″ leash for small dogs, and a 1″ collar with the 1″ leash for larger or stronger pullers.

Unisex · 6 mm hand-stitched leather · snap closure with a ½″ extender. Measure where the bracelet will sit — snug but not tight.

• S — 6.25–6.75″ wrist · 16–17 cm
• M — 6.75–7.25″ wrist · 17–18.5 cm
• L — 7.25–7.75″ wrist · 18.5–19.5 cm

The matching bracelet is unisex and woven in the same country palette as the collar, so the dog and the person wear the same colors. Measure where the bracelet will sit on the wrist — snug, not tight — and the ½″ extender covers anyone between sizes.

When a measurement falls on a boundary — say a 14″ neck that reads as both S and M — choose the larger size. Amu collars adjust down across their full range, so a roomier collar still cinches to a perfect fit, while one ordered too small can't grow. Because every piece is made-to-order in 2–3 weeks, this one decision saves a full reorder cycle.

The first walk is the best fit test because it shows how the collar behaves when the dog turns, sniffs, pulls, and shakes. After ten minutes, check whether the collar has rotated, whether the buckle moved under the jaw, and whether you can still slide two fingers under the webbing. If the collar slides over the ears, tighten within the adjustment range or move up only if the neck measurement was taken too loosely.

Watch the fur around the buckle and D-ring after the first few uses. Flattened fur is normal; redness, rubbing, or a collar that constantly tilts means the width or size may not match the dog. For growing dogs, repeat the measurement every few weeks and leave enough adjustment room for coat changes, seasonal grooming, and normal weight shifts.

If you are buying a gift, avoid guessing from breed alone. Ask for the inside length of a collar the dog already wears, measure that collar flat from buckle contact point to the favorite hole, or request a quick neck measurement from someone in the household. Those checks are more reliable than breed charts because two dogs of the same breed can carry very different neck sizes.

For a full matching set, settle the collar first, then choose the leash width and bracelet size. The collar is the piece with the least tolerance for guesswork. Once it is right, the leash and bracelet become straightforward ways to repeat the same country palette without adding fit risk.

A good size guide should help the buyer make one confident order, not three cautious ones. That is why the chart, measuring steps, between-size advice, and bracelet notes belong on the same page: they remove the small uncertainties that delay checkout.
