How to Stop a Dog From Pulling on the Leash

Dogs pull because it works. The veterinary advice we found is to stop rewarding it and reward the slack leash instead, with a 6 to 10 foot leash, a harness with two clip points, and patience measured in months.

Reward every moment the leash is slack, with small treats delivered often. Use a leash of 6 to 10 feet and a properly fitted harness, not a pain-based collar. Expect several months of practice, not days.
How We Select Products: We compare manufacturer specifications and analyse hundreds of verified buyer reviews on Amazon. For leash training we set the criteria first from veterinary guidance (leash length, harness design, rewards) and only then look for products that meet them.

Why Dogs Pull

VCA says dogs pull to reach where they want to go and to engage with their surroundings, that they naturally lean in against collar pressure, and that pulling is effective from the dog's point of view whenever it gets them somewhere.[1] That last point is the whole training problem: every time pulling works, it is rewarded. The fix is to make walking on a slack leash the thing that gets her forward.

The Method: Reward a Slack Leash

VCA's steps, in short:[1]

  1. Start somewhere quiet with small treats.
  2. Wait for any slack in the leash, mark it with a word such as "Yes!", and deliver treats.
  3. Lure and reward often, with treats every two to three seconds while walking.
  4. Add a cue such as "Let's go" once loose-leash walking is reliable.
  5. If she pulls, move away from the distraction, wait for slack, then reward.

VCA also says not to expect quick results: it takes most dogs several months of regular practice.[1] Rewards are not only treats. VCA lists praise, intermittent treats on the walk, and forward progress toward whatever she wants to sniff.[1]

Equipment That Helps

VCA recommends a leash of 6 to 10 feet and says to avoid retractable leashes because of friction burns.[1]

For collars, VCA advises avoiding slip, choke, prong and electronic training collars because they rely on pain, and says a flat collar is not suited to a dog that pulls hard.[1] It prefers H-style or Y-style harnesses that let the shoulders move freely, with no straps across the front of the shoulders, that cannot be backed out of, and with at least two clip points: one between the shoulder blades and one at the front below the neck.[1] A head halter is also an option, but VCA says it needs careful introduction and a backup leash.[1]

PetSafe Easy Walk No-Pull Dog Harness

A front-clip harness; the listing says the front attachment helps you guide your dog and that it was created by a veterinary behaviorist.

Pros

  • Front-chest leash clip, per the listing
  • Less coverage than many harnesses, so lightweight, per the listing

Cons

  • The listing describes a front clip only; VCA looks for a harness with two clip points, one on the back and one on the chest
  • Fit depends on sizing: measure before ordering

What Not to Do

VCA says not to tighten the collar when a dog strains toward something, because it risks building a fear or aggression association with whatever she is looking at.[1] Do not use pain-based collars, and do not rely on a retractable leash.[1] Puppy owners may also want our guide to puppy chewing and teething.

About Liv
Co-founder & Lead Reviewer, PawPicks · Haarlem, Netherlands

I live in Haarlem with two dogs, Teddy and Bear, and a cat called Fountain. Seven years of that, and most of what I know I learned by getting it wrong first. I co-founded PawPicks so that you can check before you buy instead of after, and I say plainly when the evidence behind a popular remedy is thinner than the label suggests.
