So I have no idea what worms, worm eggs, or parasites look like in a dog's poop and I thought I'd get someone else's opinion. Is this undigested food or something unhealthy? I didn't see anything stringy or moving, just some of these white specks, or chunks, whatever you want to call them. We have a 5 month old pitbull/american bulldog mix. We just bought him from a family who seemingly didn't take very good care of him. He hasn't even been vaccinated yet or gone to the vet for a checkup and I think they probably neglected or mistreated him. We're going to take him to the vet ASAP regardless, but in the meantime, I just need some poop help, please, if anyone is knowledgeable on the subject. And sorry for the graphic pic.
