We have the Outward Hound Sling and I love it. We use it so Chewy can go with us on the morotcycle. He loves it! It's almost like he's sitting in my lap. I put it over my opposite shoulder so I don't have to worry about losing him. It has two clips, I can hook one to his harness and as an extra precaution one to his collar along with a strap that goes over his back. I feel very secure while he's in it,
I know he can't jump out and he loves putting his paws over the edge and catching wind in his face! People are always pointing to him and smiling. I can rest on the bike with him just resting on my leg. They don't hardly weigh anything. I got it on sale at Petco for about $20 including tax.
