Collar or harness? The answer for most goldens is both: a flat collar for ID tags, and a harness for walking. Here is how to decide, how to size each and what to avoid.
The quick answer
| Situation | Best choice |
|---|---|
| Everyday ID and tags | Flat collar |
| Walks with a puller | Front-clip or dual-clip harness |
| Walks with a calm walker | Either, based on your dogās comfort |
| Dog who slips collars | Martingale collar or well-fitted harness |
| Car travel | Crash-tested harness or a secured crate (harness guide) |
| Dogs with neck or throat problems | A harness, as advised by your vet |
| Training a puppy | Lightweight harness or collar, with treats |
Why a harness for walking?
A harness takes pressure off the neck. If a strong golden lunges to chase a squirrel, a collar takes the force on the throat, while a harness spreads it across the chest. That is why many vets and trainers prefer harnesses for walking, especially for dogs who pull or have neck issues. A harness is not a cure for pulling, though. See leash pulling in goldens.
Why keep a collar?
- It holds ID tags. Even a microchipped dog should wear a tag, since a tag can be read immediately.
- Itās quick to clip on for a trip to the yard.
- Some places require a license tag on the collar.
Remove the collar when your dog is in a crate or playing with another dog if there is any risk of it catching.
Collar types
| Type | Good for | Cautions |
|---|---|---|
| Flat buckle | Everyday ID | Dogs can slip out of loose ones |
| Martingale | Slippery heads | Must be sized so it canāt tighten fully |
| Breakaway | Cats, not usually dogs | Too weak to hold a strong golden |
| Rolled leather or fabric | Long coats, since it reduces matting on the neck | Can be hard to find in large sizes |
| Prong, choke, shock | Not recommended | Can injure the neck and damage trust |
The American Veterinary Society of Animal Behaviorās position statement recommends reward-based training and says aversive tools should not be used. Goldens are eager to please and respond well to rewards.
How to measure
Collar:
- Wrap a soft tape around the neck where the collar sits, high on the neck behind the ears.
- Add about two fingersā width of space.
- Choose the size range that includes that number. If you are between sizes, go bigger and adjust.
Harness:
- Measure around the widest part of the chest, just behind the front legs.
- Compare with the manufacturerās chart.
- Check that straps donāt rub and that you can fit two fingers under them.
Goldens have thick fur, so feel the actual neck and chest, not just the coat.
Puppies
Puppies grow fast. Buy an adjustable collar and check it every week or two. A too-tight collar is dangerous, and a too-loose one can slip over the head. Our puppy shopping guide covers other essentials: what to buy.
Fit test
- Two fingers can slide under the collar or harness straps
- It doesnāt rotate, chafe or leave marks
- Your dog moves freely, with no coughing or gagging
- You can see the skin under the strap with no sores

Frequently asked questions
Should a golden retriever wear a collar all the time?
Many owners keep a flat collar with ID tags on at all times for safety, then use a harness for walks. Take it off during crate time if it could catch, and check the fit often.
What collar size does an adult golden need?
It depends on the individual dog. Measure the neck where the collar sits, add enough room for two fingers, and choose the size range that fits. A thick golden neck ruff can hide the real measurement, so feel for it.
Are prong or choke collars okay for goldens?
Veterinary behavior organizations recommend reward-based training and advise against aversive tools. Goldens are eager to please, and rarely need harsh equipment. Ask a qualified trainer.
What is a martingale collar?
A martingale has a loop that tightens slightly if the dog pulls back, but only to a set limit. It prevents slipping out and is not a choke collar when sized properly.
How do I get my puppy used to a collar?
Put it on for short periods with treats and play. Most puppies ignore it within a few days.
