One of my neighbors in our complex has a Great Dane. He lives pretty far from me so I don't see it much, however I know all the dogs that live here. His poop is enormous, I have the next smallest dog at 71lbs and his isn't near the size. My issue is that all the Dane's poop is covered in almost white-sting like stuff - hair like. Is this worms? I couldn't find anything about short hair like strands in poop. I clean up my dog's poop, but I would like to leave a note and maybe notify the landlord their dog is leaving worm-infested droppings. They always leave it right on the edge of the grass area, too - so I get to look at it everyday when I go out, and get a great smell with the humidity and rain. Thanks for any help.
