Home / Size Guide

Find the perfect size.

Measure your dog, compare the measurements with the size chart, and choose the size that gives the best adjustment range for your dog's build.

01 · How to measure

How do you measure your dog?

Use a flexible measuring tape

No measuring tape? Use a piece of string and measure it afterwards with a ruler.

Measure at the widest point

For a harness: measure the chest just behind the front legs. For a collar: measure the neck at the narrowest point, just below the head.

Measure close to the body

Keep the tape close to the body without pulling it tight into the coat or skin. Measure twice if your dog moves.

02 · Dog Harness Size Chart Dog Harness

Measure the chest at the widest point, just behind the front legs, and the neck just below the head. Both measurements need to fall within the size's range.

Size	Chest circumference	Neck circumference
XS	30,5 – 38,1 cm12 – 15 in	22,9 – 25,4 cm9 – 10 in
S	38,1 – 53,3 cm15 – 21 in	27,9 – 33 cm11 – 13 in
M	48,3 – 68,6 cm19 – 27 in	35,6 – 43,2 cm14 – 17 in
L	63,5 – 96,5 cm25 – 38 in	40,6 – 55,9 cm16 – 22 in

Tip: Between two sizes? Compare your dog's measurements, body proportions and the available adjustment range instead of automatically sizing up. The harness adjusts at 4 points.

03 · Collar Size Chart Collar

The collar is available in four sizes: XS, S, M and L. Measure the neck at the narrowest point, just below the head.

Size	Neck circumference	Band width
XS	18 – 25 cm7.1 – 9.8 in	1,3 cm0.5 in
S	20 – 30 cm7.9 – 11.8 in	2 cm0.8 in
M	30 – 38 cm11.8 – 15.0 in	2 cm0.8 in
L	38 – 46 cm15.0 – 18.1 in	2,5 cm1.0 in

Tip: You should be able to hold two fingers flat between the collar and your dog's neck.

04 · Dog Leash Size Chart Dog Leash

The waterproof leash comes in two sizes and is adjustable: the regular length is its full length, the short length its shortest setting. The hands-free leash is one-size.

05 · FAQ

Frequently asked questions

How do I measure my dog for a harness?

Measure the points requested in the size chart with a flexible measuring tape. Keep the tape close to the body without pulling it tight into the coat or skin.

I'm between two sizes, which do I choose?

Measure again and compare all required measurements, your dog's body proportions and the available adjustment range. Don't automatically choose the larger or smaller size.

What if the size doesn't fit after all?

No problem. Je kunt het product binnen 30 dagen retourneren. Return shipping costs €7.50. If you're unsure about the size, contact us and we're happy to help.

What size for a puppy?

Measure your puppy and use the size chart instead of choosing by breed alone. Recheck the fit regularly during growth and after noticeable growth spurts.

Is the hands-free leash suitable for large dogs?

Yes, up to 36 kg. The hands-free leash is one-size and adjustable from 130 to 260 cm. It's made from braided polyester rope with silicone components and zinc-alloy hardware — a different material from our waterproof leash, which is flex-poly coated nylon.
