Best harness I have ever used

Has to be the best harness I have ever used. The poop bag holder is integrated into the harness — brilliant idea. I also bought the matching leash, which you need to make the Click & Go system work. The latching mechanism is super easy to use and is solid. Easy to put on and take off. It is not coming apart once connected and is surprisingly easy to use. The harness latches use the same latch system which is fantastic. Getting the harness on and off is so easy. It has reflective piping which is great at night. I also like the traditional D-hooks so I can use it on a long leash and hook him up to the 25 foot lead I have in the back yard.

Perfect fit — my favorite harness

The large harness ended up being a perfect fit! My dog is an Australian Shepherd mix and weighs 38 pounds. The medium went on, but we had to extend it all the way and it was a little snug. He’s very comfortable in the large and I’m very happy with it! Thanks for checking in and thanks for all your help. This is definitely my favorite harness that I’ve tried.

Hands down a life saver

I am a huge fan, very easy to use. I bring him with me to jobsites/estimates, and just being able to pop the collar and harness on and off via the magnet is hands down a life saver when juggling other things in my hands!

Works perfectly, easily and with confidence. Will be buying more.

I have 4 dogs. 3 large and one small (I bought the collar for the small one). I tested out this harness on my most pull-hardy dog and it worked like a charm keeping her tight and under control. I used the Magnepup leash which makes the click and go so simple. I also used a regular leash on the D ring which gives it lots of flexibility. The poop bag storage and dispenser on the front of the harness is very convenient and keeps me from needing to have similar dangling from my leash. I will buy 2 more so I have one for each of my large dogs. They get their own color!

A brilliant harness design that takes seconds to secure

This is such a cool and thoughtfully designed harness. Kudos to whoever created the magnetic Click & Go buckle because it makes putting a harness on my pup incredibly quick and easy. I no longer have to struggle with him, guide his legs through complicated openings, or spend several minutes trying to get everything connected correctly. It now takes about two seconds to secure the harness and be ready to go. I was slightly hesitant at first because the magnetic buckle system is different from the traditional clips I am accustomed to using. After trying it, however, I was impressed by how securely it locks into place. The connection feels strong, the harness stays positioned properly, and I have no concerns about my pup accidentally getting loose.

High-quality harness, easy to use, and the magnetic buckle is actually worth it

This harness is extremely well-made and the magnetic buckle system is the standout feature. It really is a one-hand click-and-go setup, and it locks solidly without any fuss. The adjustment range is wide, so getting the fit right is simple, and the harness doesn't interfere with movement. The reflective stitching is a nice touch for night walks. The built-in waste bag holder is actually useful — not a gimmick — and keeps everything off the leash. The top handle gives you quick control when you need it. You can use your regular leash on the D-rings, but the magnetic leash makes the whole system even easier.

Perfect harness

This harness has been a great upgrade for my dog. The adjustable straps made it easy to get a snug comfortable fit and once it's on it stays securely in place without shifting around. The magnetic Click & Go buckle is one of my favorite features. It makes putting the harness on and taking it off much quicker especially when my dog is excited to go outside. The one hand release is also very convenient.

Amazing quality harness — easy to use and great control

I'm very happy with this harness! The quality is excellent, and the magnetic Click & Go buckle makes putting it on and taking it off so easy. Before using this, I had a hard time controlling my dog during walks, but this harness gives me much better control. My dog walks comfortably beside me now. Highly recommend.

The premier harness of harnesses

You may think — wow, this harness is expensive — well I'm here to tell you that while slightly more expensive than most, this is the best harness I've ever owned. The sides are magnetic which makes it super easy to put on and take off your dog. The thickness of the material is perfect and there is a nice grab handle. It easily adjusts, and the appearance is very appealing. Overall the price point based on quality, function and sturdiness is right on. The best harness ever.

The best harness we've ever had!

Our little 15 pound dog is a Houdini when it comes to escaping from harnesses. We've tried several different types and brands, but to no avail. She's always been able to escape every harness, the first time she wears it. When this arrived, I was very impressed with the quality. You can see and feel the quality of this harness. It is so well made. I ordered the size that seemed correct for our dog's measurements — these harnesses run true to size. It fit our dog perfectly. The clasps are magnetic and have an extremely strong hold.

Only harness you're ever going to need

This has to be one of the best harnesses I have ever seen. It's very easy to put on your pet. It adjusts very easily and looks great! It has breathable mesh and two places to attach a lead in addition to the magnetic leash attachment that works with the Magnepup leash, so you can use it with your existing leash. Once you try this and see how easy and convenient the magnetic connectors are to use, you will want to get the leash and collar from them. I was so impressed, I ordered them already. It's extremely durable and clearly a very well made and well thought out product.

SUPER easy for hands to use

If you have arthritis, limited hand strength, or any hand mobility issues, this is hands down the best dog harness I've found. The patented magnetic buckle system is a game changer — the self-guiding magnets line everything up, and the buckles lock securely with very little effort. No more struggling with stiff clips or pinched fingers. I was amazed! The harness is also thoughtfully designed with comfort and safety in mind. The breathable material fits comfortably, the reflective stitching adds visibility for nighttime walks, and the top grab handle gives you extra control when needed. I also love the built-in waste bag holder; it's a simple feature that makes walks more convenient.

Innovative buckle design that's made walks noticeably easier

This harness has been a genuine upgrade from a traditional buckle design. The magnetic click-and-go closure works exactly as advertised, quick to snap together and release with one hand, which has been especially helpful when juggling a leash, waste bags, and a squirmy dog all at once. It's held its magnetic strength well so far, no accidental releases during regular walks or more energetic pulling. The adjustable fit made it easy to dial in a secure, comfortable fit for our dog's specific measurements. The reflective stitching is a nice safety feature for early morning or evening walks.

High quality

Great design and really high quality! Would absolutely buy again.

Align. Click. Go.

Magnetic alignment does the aiming for you. Internal latches lock onto the grooved post and stay closed until you press both release buttons. Wiggly puppy, gloves on, coffee in the other hand — it still clicks on first try.
