Sorry this is rather gross.... My 4 month old puppy had soft poo, turns out it is worms. He was given stronghold by the vet a month ago that was suppose to prevent worms as well but it obviously didn't work! His soft poo had been on and off ever since we collected him but were told we didn't need to give an oral wormer as well as the stronghold. Anyway, he went to the vets on Monday and was given Panacur and has been pooping roundworms ever since. One was huge (about 6 inches)hmy: the others not so big. Also in his poo there are hundreds of white flecks. I know that tapeworms are excreted looking like grains of rice, but the only way I can describe these are like grains of rice but much much smaller. They are about 1mm long and quite thin, I haven't seen any moving. Has anyone else seen this in their dog's poo or know what they are? I have been told they maybe the roundworm larvae, but I thought these were too small to see with the naked eye?
