these are the best! A friend of mine has this company and I was the first to buy one.
They go on the dog like a vest with head, tail, arms and legs sticking out. It then velcros up over the dog and has handles and shoulder straps on it which you can turn into a leash.
They are so cute and I know Paris Hilton bought one. I have the pink biker one.
The only thing is I think they are better for girls because there is no escape hatch for the boys to go wee wee.
I got the mesh one for the beach. Sometimes my husband and I surf fish and I can put my boo in the mesh one and hang him off my hip. He's right there with me, out of the water and he's happy!
