If you deal with lots of dog poop (I do!) then you have to deal with what to do with the poop, too. For a long time I was a believer in the biodegradable bag -- a great option if your garbage goes to a landfill where the bag will come into contact with oxygen. But in many locales, the bags never get to air and therefore will not degrade.
At your home, you can put the pickin's in the green bins where they will compost. You can also look into a pet waste composter -- ridiculously easy to build and your garden will thank you (do NOT use near your vegetable garden and you cannot mix in your veggie scraps -- it has to be dedicated to pet waste).
But lately, I've gone even more green than green should be. Living in LA, there is lots of ivy. And due to the sunny climate, some of the ivy leaves grow into gigantic salad plate size affairs. Coincidentally the exact right size to use as a poop grabber. I just take a few leaves with me on my walks and, after picking up the poop, deposit it into someone's green bin.
No fuss, no mess, and no footprint.
