What Size Collar Does a Goldendoodle Need? | Measure The Neck, Not The Breed

For the full breakdown, see our best Collar For Goldendoodle guide.

Goldendoodles are a crossbreed, so there is no breed standard pinning down a neck size, and any chart that claims one is guessing on your dog’s behalf. Start by measuring the dog, not researching the breed. That measurement is a number you can use on any brand’s sizing chart.

This article explains how to take that measurement, what published ranges suggest for Goldendoodles, and why the manufacturer’s chart still decides the final order.

How To Measure A Goldendoodle’s Neck

The measurement that matters comes from midway between the ears and shoulders — where the collar actually sits — and no place lower. The DogIDs sizing guide and PetSmart’s collar chart both point back to the neck measurement, not the breed label, as the deciding number.

1. Place a soft tape measure around the middle of the neck, in the spot the collar rests.
2. Keep the tape snug against the coat without compressing fur or skin.
3. Check that two fingers slide between the tape and the neck. If they don’t fit, loosen it.
4. No tape measure? Wrap a string around the same spot, mark where the ends meet, then lay it against a ruler.

If the dog already wears a collar that fits well, lay it flat and measure from the buckle to the hole currently in use. That gives you the exact working number without putting a tape near the dog’s face.

When the measurement is done, choosing the collar is a shortlist problem. Our roundup of the best collar for Goldendoodles pairs brands with the neck sizes they run — useful once you have that number written down.

What Sizes Do Goldendoodles Usually Wear?

Published guides commonly put mini Goldendoodles around 14–16 inches, with the broader Goldendoodle chart landing at 16–22 inches. Both figures are averages from sources, not a standard, and individual dogs drift on either side of them.

Weight-based charts track the same trend loosely. Reported collar ranges in one size chart are 11–15 inches for dogs from 11–25 lbs (Small), 13–18 inches for 26–55 lbs (Medium), and 16–24 inches for 56–80 lbs (Large or Extra Large). A stocky mini and a lean standard can wear the same collar, which is exactly why the tape beats the label.

Width is the other sizing choice. One chart lists 5/8-inch width at Small and up to 1 inch at larger sizes — wider collars generally suit bigger dogs, but the product’s own chart decides.

Mistakes That Cause The Wrong Fit

Most sizing errors come from measuring the wrong spot or trusting an average over the dog. Moving the tape down toward the chest, for instance, adds inches that don’t exist at the collar line.

• Pulling the tape tight. Compressing the coat under-sizes the collar and makes it uncomfortable.
• Skipping the two-finger check. The gap is the comfort rule, and it catches snug but not tight before you order.
• Buying by breed average. Two littermates can differ by a full size band.
• Ignoring the coat’s fluff. One guide suggests measuring before and after grooming and taking the larger number, which keeps the collar wearable at both coat lengths.

A collar that is too loose can slip over the head; too tight is uncomfortable and unsafe. Published size ranges vary by manufacturer, so DogIDs collar sizing guide and the specific brand’s chart should confirm the final size before you buy.

FAQs

Should I size up for a fluffy coat?

Measure the neck with the coat at its longest rather than automatically sizing up, then confirm the two-finger gap. Since the Goldendoodle coat length changes with grooming, one guide recommends checking the measurement before and after a trim and ordering by the larger of the two results. That covers the dog at both lengths.

Is a 16-inch collar right for a Goldendoodle?

It can be, but only if the tape says so. One Goldendoodle chart reports a 16–22 inch range overall, so a 16-inch collar sits at the low end of that band. A mini might wear 14 inches or less; a large standard might need over 20. The brand’s own chart still makes the final call.

Does collar width matter as much as length?

Length decides the fit; width is a matter of proportion and comfort. One chart lists 5/8-inch width at Small and up to 1 inch at larger sizes. Wider collars generally suit larger Goldendoodles, but the correct width depends on the individual product’s own sizing chart, so check it alongside the neck measurement.
