We also have been having that problem with our new puppy. Our 10yr.old Rottie doesn't eat it. I asked that question here and several people said that it is not a problem. My nieghbor on the other hand says that her dog eats chicken poop and gets worms from it, so they give their dog worm pills every month. I guess that we will have to do the same as we also have some plants on our property that will give them worms if they eat it, grasses and weeds and our puppy loves to pull up weeds and drag them around. My DH is afraid that he will start eating the wild bird poop and get west nile virus.
