Short answer: for a big dog that pulls, look for a harness with a front leash clip (it helps turn your dog back toward you when he pulls), a back clip for calm walks, and a grab handle on the back so you can hold him close at curbs and crossings. Fit matters more than any feature.
What to look for
- Two leash clips. Front (chest) for pulling days, back for easy days. One harness covers both.
- A handle on the back. When a squirrel shows up, closing your hand on a handle is faster than reeling in a leash. A second, upright handle gives you a grip to help a big dog into a car or up a curb.
- Adjustable chest and belly straps. Set them once, then use quick-release buckles to get it on and off.
- Reflective trim if you walk early or late.
- A size chart in inches based on the chest, not just the dog's weight.
What a harness can't do
No harness trains a dog. A front clip helps redirect pulling and gives you more control, but the training is still on you. If your dog pulls hard every walk, a trainer is worth it.
Handle vs. no handle
A plain strap harness is lighter and cheaper. A harness with handles makes sense if your dog is big or strong, if you cross busy streets, or if you help your dog into a car. If none of that is you, you may not need one.
How it should fit
- Measure the widest part of the chest, just behind the front legs.
- Pick the size by that number. Between two sizes? Size up.
- Tighten until two fingers fit under each strap. Too loose slips; too tight rubs.

FAQ
Will a front-clip harness stop my dog from pulling?
Not on its own. It helps redirect pulling so walks feel more controlled. Training does the rest.
Is a harness better than a collar for a dog that pulls?
It depends on your dog. A harness attaches the leash at the chest or back instead of at the neck, and a front clip helps redirect pulling. Pick the one that fits your dog and your walks.
How tight should a dog harness be?
Snug enough that two fingers fit under each strap, and it shouldn't slide around when your dog moves.
