Life Changing Harness for our Active Pup!
We have a super active vizsla puppy. Naturally, he pulls like crazy on the walks, especially when he sees a bunny, squirrel, or literally any kind of bird. The walks on the collar were zero-level enjoyable. Then our trainer recommended a front-clip harness, and I found this PetSafe one that has both front and back D-rings, and also a seatbelt attachment. I haven't figured out why this works better than the collar (since the collar almost chokes him when he pulls and yet he pulls, but this one seems super comfy and yet he doesn't pull), but it works like a charm. We now love our walks, and my 9yo kiddo can also take him out without being afraid of a faceplant. The harness is great quality, we have the teal which is lovely, and it has reflective accents as well which I really like. We have a medium for our vizsla (6mo - at the smallest setting) - be sure to check their sizing guidelines before ordering. THIS HARNESS IS HIGHLY RECOMMENDED! I will add that I had a question and reached out to PetSafe and their customer service is the BEST I have ever experienced. Their chat function starts off with an automation (not a bot, but automated options to click through), but they don't put you through a hellhole of botland, very soon I was linked up with a real person who was extremely professional, very friendly and sorted me out in no time. I would buy from this company any day, their product support is 10/10.

Great with some design issues
Best harness for my dog that I've found so far and I've tried 7 different types at this point. But even if not, it's very well made, very adjustable, easy to put on, and she hasn't been able to slip out so I give it high marks regardless. I also like that it doesn't have to go over her head since she hates that. She also dislikes wearing collars and harnesses in general and does the shake-outs very often when she has something on but seems to do that less so with this harness so I assume it's fairly comfortable even for her. There are some design "flaws" that knocked it down to 4 stars for me, plus some issues for my dog in particular (that I'll list in case anyone has a similar doggo) but these didn't affect the star rating. I'd still recommend the harness overall! Design "Flaws": 1) The neck/shoulder adjusts smaller on one side than the other. If you adjust that one side more, it makes each side uneven and twists the harness a bit on your dog. (You can kind of see it in the photo where the grey belly strap meets the neck strap in the front... it's pulled to her left instead of sitting in the middle of her chest.) So even though it's possible to make the neck smaller overall, you shouldn't really adjust that far on the one side because it's not even with the other side and it messes with the fit. 2) The neck and chest straps (teal in the photo) seem to stretch a bit when wet, loosening the harness on your dog. It rains a lot here and any time the harness gets wet enough, it gets a bit loose on her in the middle of a walk. Not so loose she'd slip out or anything, but loose enough that it doesn't function as well because it's moving around on her and she ends up being able to pull more. (It's not the adjustment sliders moving on these straps. I have them marked so I could tell if they'd moved. The adjustment sliders are in the same place as always. The straps just apparently stretch some when wet and go back to normal when dry.) 3) The adjustment slider on the belly strap doesn't stay in place. For my dog, I have it adjusted so the strap is as short as it'll go but I frequently take the harness off after a walk to find the slider has moved a bit and loosened the strap. This belly strap with the adjuster on it is smaller and less textured so the adjuster just seems to slide more easily? It doesn't seem to affect things too much for my dog but it does happen so noted. Dog-Specific Issues: These aren't enough to make me ditch this harness. Like I said, it's the best I've found for my girl! But: 1) The main issue with her is that her chest is apparently rather large compared to her neck/shoulders, so I have a bit of a problem finding things that fit her around both. Usually if it's big enough for her chest, it's too big around her neck/shoulders. Because of the adjustability with this harness, it does fit her in both areas, but the issue mentioned above with the neck/shoulder strap not adjusting evenly on both sides does make things slightly awkward. 2) The front martingale loop does definitely help with her pulling. Not completely—she's a VERY strong puller and likes to chase things—but it's definitely improved our walks and makes her have to pay more attention to me/the leash. The issue here with the harness itself is that the D-ring falls quite low on her, between the front legs almost. She's a 40lb Jindo Mix so not tiny but not very tall. She's also always got her nose to the ground and kind of "prances" when she walks, where her legs lift up a bit high every step. So all that combined with the leash being lower, she ends up stepping over it all the time and getting tangled. I can help mitigate this with careful maneuvering of the leash depending on what she's doing, but it is disappointing to have to instead of playing/interacting more with her directly on a walk. It wouldn't be an issue if the ring were higher up on the strap but I think her size, gait, and activity on walks contribute to this more than the harness itself so I can't fault the harness. I've actually purchased PetSafe's other easy walk harness that has the martingale across the chest instead of the belly and the front D-ring sits a bit higher up just to see if that's any better. (Although I think this one with the belly strap will end up being the best for her overall. We'll see!) Anyway, great harness despite a couple issues. Would recommend as long as you're okay with the "flaws", though I haven't found a better harness myself. Other harnesses have had even more issues so this has been the best harness for my girl so far hands down.

We love these harnesses!
I have purchased seven of these harnesses over the last year because I - and my dogs - love them so much. I had the old version of the Easy-Walk and it wasn't awful but definitely had it's flaws. I bought the 3-in-1 for my American bulldog puppy last spring and immediately fell in love with how it fits and how adjustable it is. She was wide-chested even as a pup, and step-in harnesses were a pain before she was trained. The 3-in-1 harness is easy to get on, even easier to take off, adjustable in every single direction, and looks super cute in the fun colors. It's also sturdy, especially for having plastic buckles, and the padded portions are nice. The little built in seatbelt loop on the back works well as a makeshift handle when necessary, too. My pup quickly outgrew the small around 4 months old, so I bought the medium...which she outgrew by 8 months old. She's now a year old and about 90 pounds (but just taller than knee high - I'm 5'3") and wears the large, which will fit for life. I also bought this harness in other colors for my four other dogs because I loved it so much! For reference, my 5 pound pug has a 13" chest and wears the XS, my 15 pound Boston terrier has a 20" chest and wears the Small, my 55 pound pit bull has a 33.5" inch chest and just squeaks into a medium, my 90 pound American bulldog has a 37 inch chest and wears the large, and my smooth coated Saint Bernard is 125 pounds with a 39 inch chest and also wears the large. My dogs don't wear collars, and these harnesses have become their regular "outfits". They all wear these harnesses daily on walks and hikes. For the most part, they're pretty well trained and don't pull, but my pittie is deaf and sometimes reactive so she has put these harnesses to the test there. No fraying or breaking, but they DO NOT wear them in the house or yard or anytime they're unattended. It should be obvious that leaving a harness on an unattended dog might result in the dog getting injured or destroying the harness. These harnesses are also NOT MEANT to be forever tools for controlling your dog. Train your dog and you won't have to worry about their constant pulling ruining expensive harnesses! (It'll also make walks way more fun for all involved.) My only complaint? That I can't get matching euro-style/multi-function leashes to match them!

Nice harness
I just got this harness and it's already so much better than the ones we've tried on in person. My dog is a 55lb year old mix with a deep chest and narrow neck/shoulders and other harnesses didn't fit well. He measured for a medium and it fits well after we adjusted the harness (measure your dog!). The front clip discourages pulling and makes walks easy and fun. Back clip doesn't prevent pulling but my dog doesn't seem to know this and pulls less whenever the harness is on just in case it might pull him sideways. The loop on the top is useful to grab my dog as needed or while changing the leash attachment point. We've also used the car attachment a few times and he settles right down to lay down in the back seat. My dog loves the harness and gets excited when I bring it out, so I assume it's comfortable. Looks well made and durable. The reflective stitching is really bright. I think this is much more comfortable for my dog than waking with a collar and it's more comfortable for me because I don't have to manage a large dog who is pulling me around. He is much calmer and better behaved with this harness so I really enjoy our walks.

Two harnesses vastly different experiences
I really wanted to like both of them. I got two for my chiweenies hoping this would be the one that fit. We tried 4 different harnesses before, the only one that worked was a step in but it let them lunge too much. Tried it on them, seemingly a perfect fit! The colors looked really good on them. Super adjustable, they don’t mind it though they are more fond of their old padded harnesses (which we still use). The teal was sturdy, a little hard to adjust at first but manageable. But! I noticed something when I picked up the black one. The packaging for the black harness was slightly open, confusing considering I knew I ordered new and was ready to write it off as flawed manufacture packing. I open it up, it looked fine. Put on my dog, again fine except strangely much easer to adjust the straps than on the teal. I took them on a walk in the yard, no big issues, just needed to shorten the belly straps a bit more. Now the second use was an actual walk. The teal is fine, shifting slightly because we’re using the front clip. The black one, my god it shifted all over the place, but especially to the left, even if all he did was turn his head. It shifted so much his leg nearly slipped so both would be in the same side! I stopped mid walk to check the straps and found them loose! What the?! It’s barely been 24 hours since we got them, no way he already wore it out. Impossible! I had no other choice but to tighten them again. By the time we got home, they were loose again!! Disappointed, the same brand and size, yet two different experiences. I’m returning the black one and reordering. Hopefully I don’t get another poor quality one >:(

I was wrong!
I owe this company an apology for my bad review earlier. Rip has grown into this larger harness and it does not rub or irritate him like it did at first. As I let it out for his widening girth the padding engaged with his sides and he is comfortable again. Just like with the smaller harness, I LOVE this harness. It’s not heavy or restrictive like others. Once again I apologize guys. You have a great product. I’ve always used this specific brand of harness. I truly love it. Always used the Medium size. This time for Rip we needed the larger size. The underside of this size is NOT PADDED. We found twin sores on each side of Rip exactly where the harness rubs. Took us some thinking to figure it out. When we compared the smaller harness to the larger one we discovered the lack of padding which resulted in the chaffing sores on his sides. I’m not sure if it is a problem with that lot or all of the bigger harness. So in short. Love the smaller one. If the larger one was padded the same, would love it.

Great harness for walk training
Product works great. We have a 6 month old Belgium Malinois and it fits her like we expected. Plenty of room to grow. She swims with it on and daily goes on walks with it. It really makes a difference with pulling having it connected to the chest ring.

Great training tool
So far all I can do is rave about this harness! I purchased it for our 5 month old Labrador retriever. It has been the best training tool next to puppy classes. It is almost like the moment I put it on her she knows it is training time. Yes she still pulls when she wants to get to something exciting her, but I have much more control and it doesn’t yank my arm off like her flat or martingale collar. Plus she doesn’t choke herself. Using the 2 leads gives me control of her head to make her face me and bring her back to my side very easily. Again this is not a fix all. I use it in conjunction with the training tips I learned at puppy class. So I know just putting this on your dog and expecting them to know what to do will not work. She did get used to the feel of it quickly. I was confused about size as her neck is still very small. I went with the medium (got teal as it was $10 off but really wanted purple :( ). I didn’t want a harness that would only fit her for a month or two. The medium is perfect with the shoulder strap at the smallest and the girth out a little bit. This should fit her forever as I can let both out a lot. I like the car seat belt loop it came with as well as the fact you can just put the seatbelt through the top of the harness. The buckles are plastic and light weight and there is padding on the straps. It seems like a well built, sturdy harness. So far no issues with the quality. So far overall I am very impressed and won’t walk my Daisy with out it. It is a much more relaxed and enjoyable walk with it!

Excelente qualidade e funcionalidade!
Recomendaria de olhos fechados se tivesse permanecido com o preço que eu paguei, mas o preço subiu bastante depois que eu comprei.

üründen memnun kaldım
göğüs tasması aynı fotoğraflarda görüldüğü gibi, çok canlı ve güzel renklere sahip. 6.5 kilo olan maltese terrier köpeğimde çok şık duruyor. bu tasmayı, tasma sapı takmak için ön kısmında da ayarı bulunduğu için aldım. çekiştiren bir köpeğim olduğu için ( bana ait olan ) lastikli, esneyen gezdirme sapı ile birlikte kullanıyorum, böylelikle köpeğim de ben de rahat geziyoruz.

Difícil encontrar tamanho que vista bem.
Machuca o peito do animal e caem pelos. Tem qualidade. Mas encontrar o tamanho correto para o animal é mto difícil. Se fica bom na circunferência do Abdômen fica folgado no pescoço. Essa dificuldade na numeração atrapalha muito. Os metais são resistentes e aguentam cães fortes, mas com poucos meses já começam a oxidar, embora não rompam, pelo menos até agora. Ter mais opções de tamanhos seria maravilhoso.

Strong durable value for money immediately rectified pulling
I have a 12 month 50kg rottweiler who pulled his full body weight on walks. It was a nightmare to walk him but iv put this on him for the 1st time today along with a halti 2 way lead and its the 1st time we have had a lovely gentle calm walk. He's enjoyed it iv enjoyed it & we've been able to use this time to do some basic training. I honestly felt we've broken down a massive barrier today & I totally recommend this broduct for your large breed pullers. All the massive padded no pull harnesses do not support a pulling dog. Iv wasted hundreds of pounds on various products but this is value for money, won't break the bank & does exactly what it says on the tin. No false or misleading advertising. This is a game changer. Strong durable & totally value for money 100%% recommend
