"Dog feces may contain parvovirus, whipworms, hookworms, roundworms, threadworms, campylobacteriosis, giardia, and coccidia." (http://aapaw.org)
These parasites will not only harm your pets, but you too, especially your children. Parvovirus is a huge killer of dogs and once they have it, it's very expensive to get rid of it. This can be greatly prevented by keeping your pets vaccinated and being sure to clean up after your pet!
Too lazy? There's a job for that! PoopButler will come to your house and clean up your dogs poop for you! Here's the link: http://www.poopbutler.com/states-oregon-pooper-scooper.
Please consider either keeping up with your dog's waste, or just hiring someone to do it for you. Pay your son or daughter if you will! Just please clean up after your pets. It's a healthier and safer way to live for you, your pets, and the environment.
