ok, Smidgey seems to have pooped up all the worms now because I haven't seen any in the last 12 hours, but on getting up this morning, I discovered 3 little piles of mucus/blood, is this normal? He seems fine, he's back to his normal lively self. I took him outside for "weewees" just now and he was trying to poop, straining and that, but nothing happened, and then he came indoors and climbed in his bed, and I noticed little blood spots on his bed, which I assume came from his bottom because of the straining. Should I take him to the vets, or is this normal after a puppy has had worms?
