Gus Stay-In Harness Size Guide

A snug fit is what keeps him in his seat. Measure his chest, find it in the chart, and you’re set.

Questions about sizing? We’re happy to help.

Stay-In Harness Sizing Chart

In between sizes? Our recommendation is to size up.

How to Measure

All it takes is a tape measure and 30 seconds.

Measuring around the widest part of a dog’s chest

Wrap the tape around the widest part of his chest, just behind the front legs. For most dogs, that’s the ribcage. Keep two fingers between the tape and his chest so the fit is snug but comfy.

A Few Sizing Tips

  1. Don’t have a tape measure? Wrap a piece of string around his chest, mark where it meets, then measure the string with a ruler.
  2. For growing puppies or dogs with extra thick coats, leave three fingers of space instead of two.
  3. Chest and weight pointing to different sizes? Go by chest.

Still stuck? We’re happy to help you choose.

Gus All-Weather Leash Size Guide

Two lengths, same waterproof leash. Pick Regular to keep him close on busy sidewalks, or Long to give him room to sniff at the park.

Questions about length? We’re happy to help.

All-Weather Leash Sizing Chart

Which Length Is Right?

Regular: city walks, crowded sidewalks, and dogs who need to stay close.

Long: parks, trails, beach days, and dogs who love to sniff around.

Leash Tips

Waterproof, so a muddy walk rinses off under the tap.

Clips right onto the back of the Gus harness.

Step-In Dog Harness Size Guide

Finding the perfect fit can be tricky. Luckily, just like dogs, our Walk gear comes in all different sizes. Use the guides below to find the size best suited to your pup!

Step-In Dog Harness Sizing Chart

In between sizes? Our recommendation is to size up.

How to Measure

To find the best Step-In Harness size for your pup, measure the widest part of their chest. For most dogs, this will be the ribcage. Place two fingers between their chest and the measuring tape to ensure a comfy fit.

Other Sizing Tips

  1. Don’t have a soft tape measure? Use a piece of string or rope and measure the string with a ruler as you go.
  2. For growing puppies or dogs with extra thick coats, we recommend adding a little extra space (3 fingers) when measuring.
  3. In between sizes? Our recommendation is to size up.

I can finally stop checking my rearview mirror every 5 seconds to see if he’s still in the car 😭

What I like most about Gus is that it clips to his harness, so if he pulls, it’s not tightening around his neck. And he’s not sliding into the footwell anymore either.

Got a medium but turns out my dog needed a large. Sent it back for a swap and that was pretty much it. The large fits him perfectly 😊

Takes two seconds to clip her in, and getting him out is just as easy. Unclip, grab the leash, and he’s ready to go.

My dog hears the car go into park and immediately clocks in as an escape artist... Now I can open the door and get his leash ready before unclipping him.

I set the length once and it stays put, no stretching. She can still sit, lie down, and look out the window, but she can’t get her chest over the edge. 

Small kit, big peace of mind.

Back clip, zero neck pull: When you stop short, the pull lands on his chest, not his throat.

Window down: He still gets his favorite part of the ride, and you stop checking the rearview mirror every 10 seconds.

No-stretch, no surprises: Set the length once, and the strap won’t stretch past it when he spots a squirrel.

Built for wigglers: The snug, escape-resistant fit keeps even the squirmiest pup in his harness.

Ride to walk in seconds: Unclip from the seat belt, clip on the leash, and you’re at the park.

  1. Put the harness on your dog and tighten the straps until it’s snug, with just enough room to slide two fingers underneath.
  2. Click the tether into the seat belt buckle and clip it to the back of the harness.
  3. Set the length so his head reaches the window but his shoulders stay inside.
  4. Slide on the buckle cover. You’re ready to roll.

Questions dog parents ask

Everything you want to know before his next car ride. 

Most dogs who jumped had never done it before. It only takes once to end up at the emergency vet. We’d love for every car ride to end with a wagging tail instead.

Yes! He keeps the window, he just can’t leave through it. Set the strap length and lock it so his head clears the window but his shoulders stay inside. He gets the breeze, you keep both hands on the wheel.

Not when the length is set right. Measure from the seat belt buckle to just inside the window, then lock it there. Short enough to keep him in, long enough to sit, stand, and lie down.

Never. It clips to the back of the harness, so a hard stop pulls on his chest, not his neck.

Dogs squeeze through half-open windows more often than you’d think, and some learn to roll them down themselves. With Gus harness tether, the window can be wherever he likes it.

The padded strap between his front legs stops him from backing out, even when he’s wiggly.

Every order comes with a buckle cover, so a curious paw can’t hit the release. 

We’ve got you. Exchange it for a better fit anytime. The only cost is shipping, nothing extra.

You need both hands on the wheel, and a leash can tangle or choke if he jumps. Let the strap do the holding so you can just enjoy the drive.
