Our boy is a Great Pyrenees mix, and he's a big boy, weighing about 145 lbs. So I bought the XL and crossed my fingers. It fits!Bought the yellow, hoping our doggo would have better visibility. Eh, some, but his fur is long enough to cover the straps, and even some of the chest piece in front. Additionally,we had to lengthen the straps to fit his chest, and the refective tape ended up on the inside of the harness when we let the straps alllll the way out. The harness is visible only on top, and a bit on his chest, so the color really has not mattered.The harness seems sturdy enough. The little handle on top is handy for walking our boy. He walks well when we use the harness, particularly when we hold the handle. He walks ok with the leash on the harness, too, but he's tall enough that using the handle is nice for walking in step together.I can't comment on durability as we've just started using it. Have wondered about the durability of the plastic rings for attaching the leash. Our dog is large, and has so much strength without even trying, that we've been watching the plastic rings. I'll try to remember to come back with a durability update.Update:Um...so about the durability.... The fourth time the big boy was hooked to his chain (not leash walking) he separated the strapping (see picture) and Houdini-ed out of the harness. I thought it was cinched tightly enough, and in my defense he has A LOT of fur and "extra" skin, so I'm not sure how much more tightly I could fasten it. He was chained up to the harness for some outdoor sedentary time before coming in for his snack after an off-leash, free range frolic. APPARENTLY he decided he needed more frolicking. On an up note, the plastic fastenings and rings all held fine. LOLI tend to not fault the product, as our youngster has defeated most products designed for his safety. (He blew through the Elizabethan collar in less than an hour after surgery to prevent him bothering his stitches. He ate through the rubber muzzle, after the same injury and surgery. The inflatable collar to keep him from turning had no effect. The bandaging that we were assured we'd only have to change every other day turned into wrestling matches twice per day. He LIKED the bitter anti- licking spray. And all before he reached full size. He's never vicious, always sweet, just watches all our efforts and then does his own thing. Oy!)

My 90lb Bully loves his harness! When he sees me get it out he does circles! He is comfortable in it, and it is easy to get on and off. Very happy with this purchase so far.

I honestly just got this on a whim because of an a appointment to take my dog, once I used it I was suprised how great this is. I got a large for my German shepherd it fits perfectly an you can adjust it without difficulty, I can clip my leashe top or bottom of the dog an I love the handle to grab my dookie dog chasing after cats. Overall it's great quality not to mention the reflectors I'll definitely be getting a other one if it wears out or my dog tears it apart. 5 stars 🌟

Love this harness for our puppy! It’s not very reflective but fits great and is so easy to put on!

Georgia picked the color because she's tired of people asking "What's his name?"This harness fits well. It seems very sturdy. Both Georgia and I like a harness for walking as she isn't pulling on her neck collar. And I can control her walking better with a harness.
