Why the Right Harness Matters

A harness is more than just a way to attach a leash. The right harness improves your control and comfort, reduces the risk of injury, and can even assist with training. The wrong one can cause discomfort, restrict movement, or fail to address pulling at all.

Before buying, consider your dog's size, body shape, behaviour on leash, and any physical conditions they may have.

Harness Types Explained

1. Back-Clip Harness

The leash attaches to a ring on the dog's back.

  • Best for: Calm walkers, small dogs, dogs with trachea or neck issues
  • Pros: Easy to put on, comfortable for everyday use
  • Cons: Gives you less control over pulling; can actually encourage pulling in some dogs

2. Front-Clip Harness

The leash attaches to a ring at the dog's chest.

  • Best for: Dogs that pull on leash
  • Pros: Redirects forward momentum when dog lunges, discourages pulling
  • Cons: Can cause leg tangling if the fit isn't right; less comfortable for dogs who sleep in harnesses

3. Dual-Clip Harness

Has both front and back attachment points.

  • Best for: Versatility; dogs in training; owners who use double-ended leashes
  • Pros: Maximum control; adaptable for different situations
  • Cons: Slightly more complex to fit correctly

4. No-Pull Harness

Specifically engineered to discourage pulling through tightening or pressure when the dog pulls forward.

  • Best for: Strong pullers, large breeds
  • Pros: Effective for managing strong pullers without choking
  • Cons: Some designs can cause discomfort if misused; not a substitute for training

5. Step-In Harness

Your dog steps into it rather than having it go over their head.

  • Best for: Dogs who dislike things going over their head
  • Pros: Easier to put on anxious or reactive dogs
  • Cons: Usually back-clip only; can twist out of position

Key Features to Look For

  • Adjustability — Multiple adjustment points mean a better, more comfortable fit. At minimum, look for adjustable chest and belly straps.
  • Padding — Especially important for long walks or dogs with sensitive skin. Look for padded chest plates and underarm areas.
  • Escape-proof design — If your dog is a Houdini, look for harnesses with a second belly strap or a martingale-style backup.
  • Reflective strips — Essential for safety if you walk in low light.
  • Easy on/off — Buckles should be intuitive, especially if you put the harness on and off multiple times a day.
  • Handle on the back — Handy for lifting dogs into cars or maintaining control in crowded spaces.

How to Measure Your Dog for a Harness

Most harnesses are sized based on chest girth (the widest part around the chest/ribcage). Here's how to measure:

  1. Use a soft measuring tape.
  2. Measure around the widest part of the chest, just behind the front legs.
  3. Add 2 inches (5 cm) for comfort.
  4. Check the manufacturer's size chart — sizing varies considerably between brands.

Always check the fit once the harness is on. You should be able to slide two fingers under any strap. If you can fit your whole hand, it's too loose. If you can't get two fingers in, it's too tight.

Special Considerations

  • Flat-faced breeds (Bulldogs, Pugs, Frenchies) — These dogs often breathe more easily in harnesses than collars. Choose a well-padded option with a broad chest strap.
  • Deep-chested breeds (Greyhounds, Whippets) — Standard harnesses may not fit well. Look for sighthound-specific or H-style harnesses.
  • Puppies — They grow quickly, so prioritize high adjustability over aesthetics.

Final Thoughts

The best harness is the one that fits your dog well, suits your walking goals, and that your dog wears comfortably. When in doubt, visit a local pet store where staff can help fit the harness in person. And remember: a harness manages pulling — training eliminates it.
