Poop - pick it up. It's the right thing to do and it's the law.
10. Each time you see someone else picking up after a dog, thank him or her. A little kindness goes a long way and that person will stand up taller because of the recognition.
11. Dog poop is not good for the environment because dogs are omnivores (they eat meat like carnivores do, and plants as herbivores do). If they were totally herbivores (vegans, in other words), it would not matter as much but now, as dogs become more common (who doesn't have one or want one, or two?), we have reached and overflown the carrying capacity of the land to process the inordinate amount of dog poop deposited on the land. It stays and stays, sometimes all winter long, collecting flies. Some dogs even scoop up other dogs' poop to snack on, and who knows which dog deposited it or whether that dog had worms or other creepy crawlers.
12. When walking at night, wear something 'flashy' that reflects light or put one of those cute new lights on your dog. Take a flashlight along to locate the poop (and for other reasons).
