PetSafe Easy Walk Harness for Dogs - Pull-Free Walks - Patented Martingale Loop Design - Front Chest Leash Attachment - Adjustable Comfort Straps - Breathable Harness Design - Large, Black/Silver

I got two of these harnesses. One medium and one medium large. The medium is for my 40 pound small pitbull mix dog. The medium large is for my 50 pound springer spaniel mix.The fit is perfect for both of them. I still have room to adjust the strap on the belly. But I used most of the room to adjust the side straps. Which is totally fine, it works great still.It’s super easy to put on. The second color piece on the harness always goes around the belly. For example, the red harness has a black strap and that always goes around the chest/belly of the dog. Where the red goes around the head/shoulders. I’m keeping the little tags that mark where each strap goes just because. But I only unbuckle the chest/belly strap because all I have to do is put my pets head through the colored strap and then buckle the side strap. For example, the red one, I put my pets head through the red strap/circle it makes and then buckle the side strap. The side strap always goes on the LEFT side of the pet if you are facing their head. If they’re facing away from you(their butt towards you) like your walking, it’ll always be on their RIGHT side. Just depends on what direction you’re facing them.Overall I thoroughly enjoy these harnesses because they tighten on the chest. Cause I hate the choke collars/pinch collars/no pull collard. They can be damaging to the pets trachea or make them very uncomfortable. Anyway, this harness doesn’t allow my dog to pull so hard. Just make sure you clip the leash to the front of the harness on the ring because really that’s the whole point and to make the harness work correctly and tighten. In fact he went from pulling so hard that I felt like I did a bicep workout after a walk. I even have had times where I felt like I was gonna be pulled so hard I was gonna face plant on the ground or trip on him. With his breed he likes to pull and walk side to side a lot!! More extreme pulling though. It made it even worse because his brother the little pitbull mix would just follow along and pull really hard too. But now these harnesses have stopped that extreme pulling immediately!! I love how it tightens on the chest instead because it signals to the pet to not pull. It doesn’t hurt them at all. I feel that my dogs don’t pull because they don’t like the tightening sensation on the chest since it doesn’t allow for them to feel loose and free. This contains them and makes them realize if they pull it’s going to tighten.I don’t ever right reviews but this one was worth writing my first one. I really hope this helps. I tried to write about everything I’d want to hear from someone about this product.

My dog is a 24 lb pug mix. She is sweet and wonderful but nobody wanted to walk her! She pulls so badly and constantly. She slips out of any harness we buy her. It's awful! Ugh! She's getting chubby from lack of exercise and missing out on lots of good family fun. This harness was my last hope.I am blown away!Even after I read all the five star reviews, I was skeptical. I bought this harness and got same-day shipping. I walked her that evening and I couldn't believe my eyes! The first time she pulled, the harness snugged up on her chest and gently turned her to face me; she stopped immediately. She turned and kept walking, but slower and more mindfully. I gave her some slack in the extendable leash and then locked it down--as soon as she pulled again she immediately stopped again. That's it. Pulling is over. My 13 year old is now walking her every day and loving it! She doesn't pull, she minds the "heel" commands. If she gets too excited and starts to pull, she stops as soon as the harness snugs around her. She's starting to walk better with just her regular collar and no harness at all. This harness appears to be breaking her pulling habit entirely!!Here is what you need to know with fitting. My dog is a mixed breed and is barrel-chested for her size. I really worried that I would never get the right fit. I have a hard time buying any harness for her. If I get it large enough for her chest, it's too large for her paws and neck and she can slip it easily. We've been through many. Not the case with this one!Fitting: Measure the largest part of your dog's chest. Buy the size that most narrowly matches that chest measurement. My dog's chest is 24 inches, which fits in the size range for the Medium which is for 20-28" chest. I took her PetsMart and tried the medium on her and it was HUGE! I couldn't make it tight enough to stay on her. So I ordered the Small/Medium which is for 19-25" chest--a more narrow range for her chest measurement. I was worried it would borderline on too tight. It isn't. I had to snug it up quite a bit to make it fit her.As for putting it on and taking it off: Don't unbuckle everything!!!! It's too confusing. You only need to work with the buckle for the chest strap, which buckles at the side of the chest so you can actually see it!! These harnesses are all 2-color. The strap that buckles around her chest is the second color--in my case silver. The main color, in my case black, is the whole rest of the harness. Only unbuckle the part that buckles around your dog's chest. (See the attached photos) Stand in front of your dog. Hold the harness so the leash loop is facing you and dangling at the bottom (the leash loop is the metal circle on which you will clip the leash to the harness--it will be on your dog's chest, not the top of the back as with other harnesses). Slip the harness over your dog's head and then just buckle the colored strap under the chest and you're all set. Take it off by unbuckling the chest strap and slipping it right over your dog's head. It's not a tight squeeze and is actually so much easier than trying to slip both paws into the leg holes while holding your dog down and buckling the strap with your third arm. This is the easiest time I've ever had getting her into a harness.You need to know that this harness will loosen itself after some time walking. Not it's strongest feature, but I couldn't even take off a star for this as it is such a miracle to be able to take our dog with us to parks, walks around the neighborhood, etc. There are 4 points on this harness that can be adjusted to fit your dog's individual shape and size. This is very much a strong point for me because my dog is not perfectly proportional. When you first take it out of the box, put it on your dog and check to see which points need adjustment. I can adjust it while it's on her, but it's easier if I take it off, adjust, and put it back on. I don't have to adjust it in the middle of walks. But you should check the adjustment every time you put it on your dog.Pros: My dog doesn't pull anymore (life altering)!!! Great price (Amazon charged half what pet stores charge--I did not get a discount for this review!); easy to put on/take off; quality construction; 4 points of adjust-ability for a good custom fit.Cons: none so far (need for periodic fit adjustment is not a big deal to me)I would recommend this to a friend. I actually recommended it to a total stranger--an older lady in the pet store (without her dog) who said she has a Min-Pin she can't walk or take anywhere because he pulls her so much. I was so enthusiastic she bought one right then and there. My dog was standing there being an angel, wearing her Easy Walk Harness.Please tell me if you found my review helpful. Please ask if you have questions. Thanks and good luck! I hope this solves your fur baby pulling problem. It certainly solved mine.
