We have the doggie backpack harness. Great to get them to put on too I find as sometimes he goes "no puppy gog" and I say well then you will have to go in the pram and that fixes that problem quick smart, on goes the backpack. If he doesn't have it on he tends to bolt but with it on he really stays put a lot better and holds hands or onto the pram. I think they look nicer too

I've seen them in Target, KMart and Babies Galore.
