Labradors and Golden Retrievers are two of New Zealand's most popular family dogs, and they share a few things that make harness shopping tricky: deep barrel chests, enthusiastic pulling, and an obsession with water. Here's how to find a harness that fits properly and actually helps on walks.
Why Labs and Goldens Pull So Hard
Retrievers were bred to work all day and run after things. Add a food-motivated nose and a friendly urge to greet every person and dog, and you get a strong, happy puller. Most adult Labs and Goldens weigh somewhere around 25–36kg, which is plenty of force on the end of a lead.
That's why we recommend a front-clip no-pull harness rather than a collar or a back-clip-only harness. The front ring turns their chest back towards you when they surge, instead of letting them lean in. We explain the mechanics in our guide to no-pull harnesses for large dogs.
What Size Harness Does a Labrador Need?
Most adult Labradors fit a size L in our harness, which suits a chest girth of 70–100cm and a neck girth of 46–60cm. Working-line Labs are often leaner, while show-line Labs tend to have broader, deeper chests, so always measure.
What Size Harness Does a Golden Retriever Need?
Adult Golden Retrievers also usually fit size L. Their thick coat can add a few centimetres to the measurement, so press the tape gently through the fur to the body, then add a finger's width of slack.
How to Measure Your Retriever
- Chest girth: measure around the deepest part of the ribcage, just behind the front legs. This is the measurement that matters most.
- Neck girth: measure around the base of the neck, where it meets the shoulders.
- Compare both with the harness size guide.

| Dog | Usual size | Watch out for |
|---|---|---|
| Adult Labrador | L | Broad chest; check the neck strap isn't too loose |
| Adult Golden Retriever | L | Thick coat; measure through the fur |
| Labrador or Golden puppy (4–8 months) | M, then L | Re-measure every few weeks while growing |
| Labradoodle (standard) | L | Fluffy coat hides a narrower chest; measure carefully |
Signs the Harness Fits Your Retriever
- You can slide one finger flat under every strap.
- The front D-ring sits centred on the breastbone, not off to one side.
- The straps sit clear of the shoulder joints, so your dog's stride looks natural.
- Nothing rubs behind the front legs, which is where Labs and Goldens often chafe.
- When you gently pull the lead backwards, your dog can't back out of the neck opening.
Why Waterproof Matters for Retrievers
Ask any Lab owner: if there's water, their dog is in it. Beaches, rivers, lakes and muddy puddles all end up in a fabric harness, which then stays damp and starts to smell. Our Waterproof No-Pull Harness has PVC-coated straps that don't absorb water, so you rinse it under the tap and it's dry in minutes. Our beach cleaning guide shows the 10-second rinse.
Bright orange (Tangerine) is easy to spot when your retriever is swimming or charging through long grass. If you prefer a softer look, the Pistachio harness suits golden and black coats alike.
Best Lead for a Labrador or Golden
Pair the harness with a fixed-length lead you can shorten near roads. The 6-Way Waterproof Lead adjusts from 170cm to 240cm and clips to both harness rings for dual-point control, which is ideal while your retriever is still learning loose-lead walking. You can get both together in the Harness & Lead Walk Kit.
Training Tips for Retrievers That Pull
- Use their food drive. Labs and Goldens learn fast with food. Reward every few steps of loose lead early on.
- Burn energy first. A quick game of fetch before a street walk makes loose-lead practice much easier.
- Stop when the lead goes tight. Walk on again only when there's slack. Full method in how to stop a dog pulling on the lead.

FAQ
Should a Labrador wear a harness or a collar?
For walks, a harness. Labradors pull hard, and a collar puts that force on the throat. Keep a flat collar on for ID and council registration tags, and use a front-clip harness for walking.
What size harness for a 30kg Labrador?
Most 30kg Labradors fit size L (chest 70–100cm). Weight is only a rough guide, so measure your dog's chest girth before ordering.
What size harness for a Golden Retriever puppy?
Young Golden puppies often start in M and move to L as adults. Re-measure every few weeks during growth and adjust the straps as they fill out.
Can my Labrador swim in this harness?
Yes. The PVC-coated straps don't soak up water, so you can rinse it with fresh water after the beach. Always supervise swimming and unclip the lead in the water.
