I am not sure. You didn't mention how much you gave? However, it sounds like your pet may have colitis (inflamed colon) possibly due to the roundworms or even from additional worms that are present. Not all worms are visible by the naked eye, which is why we recommend a fecal exam (looking at the stool under the microscope after allowing any potential eggs to float to the surface using a salt based solution and centrifuge machine). I would recommend taking your pet in to the vet to have his stool examined and then he may need an additional dewormer or a short course of antibiotics (i.e. Metronidazole) +/- probiotics (you can try over the counter Culturelle) to completely resolve the suspected colitis. Best wishes with your pet and his loose stool. Take care.
