Freedom of Movement
One of the most common complaints about dog harnesses, is the chafing of sensitive skin during normal activity. The ComfortFlex sport harness is specifically designed to avoid the most sensitive areas of your dogs body allowing a full range of movement at all times.
Dynamic Handle
Our leash connection ring slides effortlessly along the quick grab handle giving you increased control over your dog while walking, running or biking.
High Visibility
The woven, highly reflective webbing and a selection of vivid colors, make these harnesses easy to see in low light or dark situations when visibility is most important for the safety of both you and your dog.
Made for Comfort
The ComfortFlex sport harness is fully padded, not just over the back and chest like most harnesses, but around the entire girth strap so that those sensitive areas are not irritated, regardless of the level of exercise.

10 Sizes to Fit Most Dogs
Measure the dog’s girth at approximately 1.5” to 2” behind the front legs. It should be a loose measurement, allowing for a little movement. Then refer to the chart for the appropriate size.

This is my 2nd ComfortFlex I've had for my Labradoodle. The 1st one is still very usable but it's over 4 years old. I love this harness! And so does my dog. When I hold it up she knows we're going on a walk and she walks over and puts her head down for me to slip the harness on. Very well constructed! 1st one was orange, this one is purple, colors are very vibrant! Great price! Easy to adjust! I recommend!

Bought this for our French Bulldog after meeting another Frenchie in our neighborhood wearing it. Frenchies are awkwardly shaped and poorly-fitting harnesses result in friction sores and hot spots. We've tried at least 10 different brands of harnesses in the last twelve months and while some have been good, nothing has been perfect. I think this harness is perfect. It fits securely, is soft and comfortable, doesn't impact range of motion, didn't lead to any friction sores or hot spots, and looks great! It also seems very well made, durable (based on seeing a 1-year old harness my neighbor's Frenchie was wearing), and super-easy to put on and take off. We love it so much we bought a second harness for our Australian Shepherd.Sizing runs true to their chart although sizing is extremely flexible. As long as the dog's girth fits somewhere in the range on the chart, the harness will be quick and easy to fit. Because of the velcro fastening system it's also very easy to change the size if you put a sweater or jacket on your dog -- no need to have a second, larger harness for the winter. Overall a great product.

Used the harness on my active Belgian Malinois on our long walk today and I am very pleased with the harness. My dog is a puller and quite strong, and I'm over 70. She has pulled me down a couple of times and I have no desire to break a hip. Today was a walking victory, with 1) ease of putting it on the dog, 2) no tangling, 3) comfort on my dog and no chafing, 4) good center of balance so I was not fearful of falling. Bought it in the burgundy color, she already wears the matching collar, and she looks quite smart. This is a good American made product. Recommended.

It is very well made, and looks very comfortable, but just didn't fit my dog. I bought it because my dog just had minor surgery and can't wear a collar for 2 weeks, and it is a little bit of pain putting her harness on every time she has to go out, then taking it off again when we come back inside. I wanted a harness that was comfortable enough for her to wear all day. In addition, I thought it might work well for her nosework classes. It may be a bit too thick or substantial for an all-day harness, but it definitely would have worked well for nosework.I have a 30lb cockapoo who has a wide ribcage, but not such a broad chest. I bought the size that fit her girth properly, but the chest strap is way too big for her, and not adjustable. The smaller sizes have adjustable chest straps, but those would never fit my dog. I'm curious as to why only the smaller sizes have adjustable chest straps.. maybe there is a good reason, but I just can't guess what it might be.I still give it 4 stars (probably would give it 3.5 if I could give half stars) because had it fit my dog properly, I would have been pretty happy with it.The cons would be specific to my dog -- for example, the sound of velcro being undone is scary to her, and this harness does have a lot of velcro. However, the velcro makes it easy to adjust to the proper size, and having a lot of it means it is not going to accidentally come off (it also has a buckle as a backup). Another issue my dog has is with harnesses being put over her head, although the opening of this one is big enough that it didn't cause her to try to hide under the table.I'm disappointed that it doesn't fit my dog, but oh well. It is easy enough to return things to Amazon that it was worth the risk.

My dog sustained a neck injury, and I had to change over from collar to harness. I love how soft this one is, and it doesn't come near his neck so there is no chance it will cause pain. Quality made, love how it has Velcro plus a buckle to secure fastening. Highly recommend it!

I love the fact that the harness doesn’t put pressure on the dogs neck and throat - when he was a puppy the L worked well as he was about 60lbs. It was only that he put on weight and grew - so now 2 years later that we bumped him up to the XL - the L is still in great condition and was well used - so we are happy to buy another one of the same brand now that he outgrew the L.We now have an 85lb dog and the xl works great to keep him on the leash but not choke him when he pulls. Easy to put on and take off of him. The color is very patriotic :) and for the price we know we are getting a good value.

Outstanding harnesses for our two dogs (pug and French bulldog). Adjustable and very easy to put on, they provide a lot of support without putting any pressure on the dogs' necks. Extremely well-made and sturdy.

Great for French Bulldogs. We tried many other harnesses and this one worked best. Our dog is very comfortable in it.

LOVE how easy it is to place on my dogs - no fiddling - just snap and its on! The handle at the top is very handy for my older dog who has weak legs and needs help standing up sometimes and for our pup it is easy to grab and restrain him if necessary. They are very light weight and we find no rubbing occurs on the fur/skin for our most active dog. Love, Love, Love them!!
