Input: So this is a good size and fit my dogs quite well, she didn't mind wearing it very much at all. The material seemed to be of high quality though, I loved that. After just two days the zipper pull came off. Now we have only one button for her harness now so she'll never zip up even if there's no pull. It was an obvious design flaw that shouldn't happen with the amount of money they charge to make these things.
Output:
Bad review
