Literally one of the best things I have ever bought. I can now walk my dogs hands-free! We run together every night, which is why I bought this and it's great. It is also just great to have if you have a clingy dog that wants to be with their person all the time. I do my gardening, cleaning outside, etc with my little dachshund right where he wants to be, right with me. I have recommended this to several friends and have had numerous neighbors ask where I got it. This is great if you live in a congested area and don't have a fenced in yard, I know my dogs are always safe attached to me.
