Bests & Worsts Reviews from Amazon

I am a certified dog trainer, and I cannot recommend this product for any dog of decent size or strength. The adjustability/fit of this is quite good, and I think my dog found it quite comfortable. But, it has 2 huge problems. First problem, the belly straps are held on one side with elastic strapping. Not only is this not strong enough for a strong pulling dog, but in addition you would never want to rely on that elastic if you are using the harness as a car restraint. Furthermore, while the flexibility of the elastic probably provides great comfort for the dog, the give that it provides causes the harness to twist/shift on the dog's body (if you dog goes to make a sudden movement, like a lunge towards a squirrel). This twisting of the harness potentially results in the dog's discomfort (which caused my dog to panic, and attempt to back out of the harness). Second problem, the plastic quick release buckles are incredibly lightweight and not nearly strong enough for a strong dog. If you read the negative reviews for this harness, the number one complaint you see if the inferior strength of these plastic buckles (which are essential to your dog staying safely restrained in his/her harness). So, in summary,....if they did away with the elastic and changed the lightweight, fragile buckles to high quality, strong buckles - then I would change this rating from a 1 star to a 5 star. But, as it is, it is not a safe harness - and it is definitely unacceptable as a car restraint. If you have a small, docile dog, then maybe you could take a chance with this (I wouldn't, personally). But, if you have a midsize-to-large, strong dog - there is no way I'd use this.
