My girls both poop and leave their post mark of pee for all the neighbor dogs to know they have been by. They also poop in the back yard as they are 3 a day poopers and we only take 2 walks. They have their favorite poop yards...the pretty ones mostly. I have gotten very good about putting their leashes on my left wrist while I pick up poop with my right hand. When I walk them both, I hate it, but have to put full poop bags in my pocket. I always take 4 when walking both girls at the same time and 2 when walking one as you never know. When walking one, sometimes I pick up for someone who forgets a bag or doesn't use one. As a result, no neighbor comments. Since most have dogs, we are respectful to one another and know that they have to go somewhere. Cecil sometimes "marks" for the other dogs, 3 times on a walk. It's just all so funny. I get to the store sometimes and realize I have blue poop bags handy in my pocket. LOL
