Very good harness, highly adjustable like promised and will fit my growing puppy for a long time. She just outgrew her medium sized pet store harness, but is an XL breed so the L harness is just slightly big on her (good so that she can grow into it).

Pros: Easy design, neck buckle, smooth material, highly adjustable, affordable

Cons: Orange harness is not orange at all, but more like pantone scarlet red. Doesnt reduce functionality just a pet peeve, otherwise the color is highly visible in the outdoors if thats what you like.

Easily adjustable and doesn't sit under your dog's armpits. No rubbing and comfortable.

I used a smaller blue 9 harness when my Mastiff was a pup and loved it, but he quickly grew out of it. I was so glad to hear they finally made one to fit giant breeds. It JUST fits my boy at 205 lbs. He's still a young boy, so I'm pretty sure he will out grow this one soon. I would Absolutely love it if a X L or an XXL one was in Blue 9s future. I would definitely buy one. We just need another inch or 2 in lengh and width to be a perfect fit for a growing Mastiff.. The quality of this item is Exellent, no complaints at all.
