It fit my Great Dane mix very well and didn't bind or irritate him at all. Sadly, after about two months it tore right up the back and he got out. A small or less powerful dog probably wouldn't have had this issue, but for large breeds the stitching might not be strong enough for an extended length of time. However, for the price it wasn't a bad deal, I just might look for one with stronger webbing or a leather backplane next.

Works perfectly on my Great Dane in largest size!

I ordered this for my (50lb.) almost, 1 year old Australian Shepard mix and it fits perfectly!  It's very well made and durable.  She use to pull terribly, but after making the switch to a harness, it has helped.

We bought two of these for our Danes since they're so sensitive to the cold...even if we are in texas.  It was about the only sweater I could find that looked like it would fit a Great Dane and was decently priced.

Both our Danes love the sweater and have no complaints about wearing it.  I love the drawstring it has, as they have huge chests and not so huge mid-sections.

The only thing I didn't like about them is that they are a little light weight.  Looking at the title, it is made out of the thermal material, but I did expect them to be a little thicker.

That being said, they serve their purpose and the Danes seem happy.  I'll buy them again.

It fits my 90 lb Alaskan Malamute nicely. It's a little loose but nothing to complain about. Easy to put on and take off and very durable.

I have a 11 month old Great Dane. At 110 lbs right now... This harness is perfect for him, and the hand hold gives my wife better control of him when we go walking....

I bought this for a 16 lb shih tzu and it works great. It fits very well, is snug and not that hard to put on her. The velcro has been doing a good job holding together and has never felt loose. Its easy enough to take off the velcro and remove the jacket as well.

Fits well, easy to adjust and put on/take off.  Using for 100# Great Dane and had no problems.

I ordered this in a size Small for my 9-pound mini dachshund and it fits pretty well, considering how dachshunds are hard to fit because of their large chests and tiny everything else. One of the buckles is placed so that I was concerned it would chafe her armpit area, but she doesn't seem bothered by it. It's a sturdy harness that Buffy seems pretty comfortable wearing for walks, and is great for correcting her when she pulls too hard because I don't have to worry about her choking herself.

Sizing chart is accurate! I followed those measurements and purchased a Medium for my 16 lb silky terrier. The clasp buckle is a little hard to open and close, but I believe it will become easier with continuous use. The mesh is great for my dog, who is prone to pulling on the leash, and the neck hole, though not adjustable, sits well on him and doesn't hang oddly like some harnesses do. I love the bright red color, and the harness itself doesn't look cheap at all. I should have bought this off the bat when I started shopping for mesh harnesses, since it's the most popular -- I would have saved quite a bit of money on other brands' ill-fitting harnesses.

**UPDATE: The clasp buckle is no longer difficult to open and close. It got less stiff with use and is now perfect!

Big enough for a Great Dane. Love the chest protection and the way it fastens on and stays on despite hard play. Not the warmest due to the light interior but it keeps them dry and is windproof.
Great Value and excellent craftsmenship.

My dog is an Australian cattle dog and whippet mix, so it's hard to find things that can accommodate his deep chest. He weighs 28 lbs and has a 24" chest, so I bought him the medium. The chest piece of this harness is what drew me to it, and I have to say that it fits my dog very well. Being part sighthound, my dog's neck is rather small compared to what would be expected for his chest measurements, so I wish the neck area of the harness was more adjustable and could be tightened a bit more, but it still fits him fine. The part that fits over his back slides forward and tightens when he pulls, adjusting to his movement nicely. The harness seems to be made out of sturdy materials; the fabric is sturdy and the straps are strong and are adjusted with heavy duty metal pieces. All in all, I'm pleased.

We have had this for three months now. We purchased the Large, Red collar for our large breed pooch. It fits great (even accommodated a 20lb. weight loss), doesn't stink and washes clean with soap, water and a sponge after every bath. We will be Dublin Dog product buyers for a long time to come!!! The last thing I will say is that the collar is Red & Black, there's no Gray to be had here, which is fine with us.

Only harness that is adjustable enough to fit my hard to fit hound mix.  She is 38lbs and a bit barrel chested, a large fit perfectly with adjustments very easy.  Only harness she has had that doesn't chafe her under her legs and she runs daily with us.  I have ordered a total of 3.

This harness in medium was perfect for our 10-12 lb. Chihuahua mix dog.  She had another one that she hated because we had to put her legs through one at a time.  She's not one who's ever liked to put on anything.  This one slips over her head easily, and I was able to adjust it quickly around the body to get it clicked in.  I highly recommend this style for anybody who struggles to get things on their dogs.  It's also a good design so she doesn't tug and choke herself.

I'd been trying to get one this style at a decent price for a long time, but her size was always sold out anywhere I went that wasn't an overpriced pet store.  I'm happy to have finally bought it through Amazon.

I bought this for my three legged dog, and it works wonderfully. It fits him great and stays in place even with his missing front leg. I highly recommend this harness for any dog.

My dog Sydney is a cattle dog mix who has very little hair on her belly and under her front legs. Personally I don't like using the normal neck collars, but every vest I had tried rubbed and irritated her underarms. Last year I found the Puppia harnesses online, and I bought her a red and white fluffy Christmas harness. It was-is wonderful, and I used it until now despite it not being seasonally appropriate, it just fit her so wonderfully! Both the Christmas and purple harnesses I got are very well made, I have put the Christmas one through the washer quite a few times, and it still looks great! We go to the beach and for walks A LOT, the soft mesh of the new purple harness breaths and dries fast if she does go in the water, it does not rub or irritate her anyplace! Plus it just looks sharp ;)
PS: Remember to measure your dogs head and not the neck, the harness has to go over the dogs head, so the opening must be big enough!
