How to Choose a Dog Harness (and the Right Leash) for Daily Walks

Knowing how to choose a dog harness makes daily walks safer and more comfortable for both of you. The right harness fits well, spreads pressure across the chest, and suits your dog’s walking style. Here is what to look at before you buy, and how to pair it with the right leash.

How to Choose a Dog Harness: Start With Fit

A harness only works if it fits. A harness that is too loose can slip off, and one that is too tight can rub or restrict movement. Measure first, then pick a style.

Measure your dog

• Chest girth: the widest part of the ribcage, just behind the front legs. This is the most important number.
• Neck: around the base of the neck where a collar would sit.
• Weight: check the weight range on the size chart too.

Match your measurements to the size chart on the product page. If you are between sizes, look for a harness with several adjustment points so you can fine-tune the fit.

Harness or Collar?

A collar is great for ID tags, but pulling on a collar puts pressure on the neck. Many owners and trainers prefer a harness for walks, especially for dogs that pull, small breeds, and flat-faced breeds. If you are unsure which is best for your dog, ask your veterinarian or a trainer.

Choose a Harness Style

• Back-clip: the leash attaches between the shoulder blades. It is easy to use and good for calm walkers, but it may not discourage pulling.
• Front-clip: the leash attaches at the chest. Many people use it to reduce pulling because it turns the dog toward you when they surge ahead.
• Vest-style: padded and easy to put on, with a wider chest panel that spreads pressure.

Our Reflective Pet Harness is an adjustable control vest in sizes S to XL. For more detail on styles, the AKC has a guide to choosing the right harness.

Check the Fit Before You Walk

1. Put the harness on and adjust the straps so it sits snug but not tight.
2. A common rule of thumb is that you should fit about two fingers between the harness and your dog’s body.
3. Check that it does not rub behind the front legs and that your dog cannot back out of it.
4. After the first few walks, look for red spots or rubbed fur and adjust or resize if you see any.

Stay Visible

If you walk early in the morning or after dark, choose a harness with reflective trim. Drivers and cyclists have less time to notice a dog on a dim sidewalk, so reflective material adds a real safety margin.

Choosing the Right Leash

A standard leash of about 4 to 6 feet gives you good control around traffic, other dogs, and busy sidewalks, and it is the usual choice for training. Longer leads give more room to explore in open, quiet areas.

Retractable leashes let your dog roam farther, which many dogs enjoy. They also take more care to use well, because a dog can build up speed and the thin cord can be hard to manage. Many trainers advise using them only in open, low-traffic areas, locking the length near roads and other dogs, and avoiding them with strong pullers. The AKC explains how to use a retractable leash safely. If you want one, our 16.5ft Retractable Dog Leash has a one-button lock.

Traveling With Your Dog

A harness is useful in the car, and a waterproof, foldable car pet cage keeps your dog contained and your seats protected on longer trips.
