01 · How to measure

How do you measure your dog?

1

Use a flexible measuring tape

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

2

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.

3

Leave two fingers of room

You should always be able to hold two fingers flat between the measuring tape and your dog. Too tight is never good.

05 · FAQ

Frequently asked questions

How do I measure my dog for a harness?

Measure the chest at the widest point, just behind the front legs. Use a flexible measuring tape and leave two fingers of room.

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

Always choose the larger size. All our products are fully adjustable at a minimum of 4 points, so a slightly larger size can always be adjusted.

What if the size doesn't fit after all?

No problem! You have 30 days to reconsider. Doesn't fit? Exchange for free for a different size.

What size for a puppy?

Start with size XS or S, depending on the breed. Check every two weeks if the harness still fits properly — puppies grow faster than you think.

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.
