A Revolutionary Dog Training Harness

The Crosscheck Harness is a training harness that reduces a dog's pulling via a girth checking system. It functions similarly to a martingale but instead performs a checking function around the dog's girth rather than its neck. This alternative limited-slip checking system allows the handler to give a correctional tug as the dog begins to pull, teaching the dog to walk beside them in an effective and humane way while doubling as a solution for escape artists.  The side checking feature is most effective when the dog is on the left side of the handler. For Best Results pair with a short non-shock absorbing leash such as the Vario 4 Leash.

An Effective No-Pull Dog Harness and Easy Walking Harness

Using a simple figure eight configuration, this harness is also incredibly easy to fit. The front section of the harness goes over the dog's head much like a Quick-Fit Harness, with the girth strap completing the fitment with a simple side release buckle connection. With two leash attachment points, the handler has the option of using the harness as a dog training harness or simple walking harness.


The Perfect Training Harness For Small and Big Dogs

The Crosscheck Harness has been successfully tested on a wide variety of dog breeds and is perfect for dogs that pull or are in training. This particular harness is perfect for puppies and young dogs that are in training. Teaching a dog at a young age not only not to pull, but to walk on the side makes for pleasant walking for years to come. The unique Crosscheck Harness feature can also be used to remedy the bad habits of a fully-grown dog that pulls.


  • Caution: Do not leave on dog unattended.
  • Caution: PLEASE do not ever leave a dog tied up. Doing so with any EzyDog harness or collar will void the warranty. Thanks for caring about the safety of your dog!

An Award Winning Design Recognized By Pet Industry Professionals

The EzyDog Crosscheck Harness is recognized by pet industry professionals.


For best fit measure the girth of the dog. This is the area behind the front legs and around the body. The neck will typically fall into place once girth is determined. If the measurement is close to the end of the size range, go up to the larger size.

Fitting Instructions

  1. Place front loop, (section with silicone liner) over dog's head.
  2. Unclip side release buckle, and feed rear webbing around dog's girth
  3. Reconnect side release buckle and tighten until snug, but not too tight (being able to fit one or two fingers in between the strapping is ideal)

    Great harness

    Posted by April Marshall on 7th Jan 2021

    When we realized our dog could slip out of more traditional harnesses, we knew we needed another option. Someone in a dog group I’m a part of recommended Ezydog harnesses. I also did a search of escape-proof harnesses and this harness was one of the top. So with those two things in mind, I purchased the Crosscheck harness for my 20 pound Schipperke-mix. Because she was right in between a small and a medium, I got the medium, as was suggested by Ezydog. I love this harness! First, it is so easy to get on and off my pup. She doesn’t like wearing harnesses, but she can’t really fight us on this because it’s on in a snap. Second, it performs wonderfully. She hasn’t been able to escape. And I love that you can clip the leash on the side, which reinforces heeling as we teach her leash manners. Third, I love that it’s a martingale-style harness but with the tightening on her girth and not her neck. This also reinforces leash manners. Overall, I would highly recommend this harness to anyone!

    Best harness I’ve ever used. Easy to put on your dog and there is no escaping the harness like other ones I’ve used.

    Crosscheck Harness

    Posted by Laila Jandick on 4th Nov 2020

    This harness did not work for my labs. It moved around a lot. The two ends of the figure 8 would shift as the dogs walked. Unfortunately I am sending the harnesses back.

    EzyDog Says: Hi Laila - We would love to assist with the fit, as we are confident this can be avoided with a few adjustments. Please reach out to us. Thank you!

    Not great for Boxers

    Posted by Katrina on 15th Oct 2020

    It's a great concept and it works WHEN it stays in place. But I would not recommend this harness for a boxer. It does NOT stay in place under the chest/girth, but slides back towards the waist area. I am constantly moving it back to where it should be. Also the neck part is quite tight but there isn't a way to make it looser without making the entire harness looser.

    EzyDog Says:
    Thank you for your feedback. For best results with deep chested breeds, after adjusting the neck, adjust the girth strap snug just in front of the widest portion of their chest to keep it from moving back. Please reach out to us and we would love to assist you.
    Thank you!

    Works like a charm

    Posted by Jessica Sullivan on 19th Jul 2020

    This harness works great for my 10 month old Blue Heeler. I like that it has 2 places to clip the leash. The only thing I wish was different is an option to choose which side to clip the leash for correction. I’ve trained her to walk on my left side, but with this harness we had to switch sides.

    EzyDog Says:
    Hi Jessica - we're stoked to hear you're enjoying the Crosscheck Harness. I'm happy to inform you that you can adjust the side leash attachment for either left or right-hand walking. We're happy to walk you through the steps. Please don't hesitate to contact us at

    Crosscheck Harness

    Posted by Chris on 25th Jun 2020

    This keeps my dog right by my side. I’ve used other no-pull harnesses and they’ve all kept him from pulling too hard but not stopped him from pulling all together like this thing has. If you have a shorter dog like I do I’d recommend using a shorter leash to keep it from dragging on the ground.

    We have only had this harness for a day and it is LIFE CHANGING. It seems a little confusing at first on how to put it on but once you adjust it to the correct size it is a breeze. We have an 80 lbs Pit bull/Great Dane mix who pulls a lot on his leash. We used it for the first time yesterday and there was no pulling at all! He stayed right next to us - it was great. We recently purchased the Neo Mongrel Web leash from a local pet store which is basically just a handle but when you pair it with this harness it is perfect - especially if you take your dog out and about and want them to stay close to you. HIGHLY RECOMMEND :)
