Just looking for some advice from anyone that could help. George was given medication for lungworms a few days ago and has since developed severe diahorrea. He took 5ml of Parazole for 2 days and has had diahorrea since. We stopped the medication and his food and have him on Royal Canin duck and rice. We brought him to the vet last night and he said that his temperature was fine and it had to run his course. Does anyone have any idea how long this lasts? We're so worried about him as it just doesn't seem to be easing up.
