Well, we have nearly finished the Baytril, but the thing that is helping him have solid poos most is Probiotic Natural Yoghurt, he has 2 spoonfuls a day, and is solid, if I miss a day, he isn't. He still isn't allowed biscuits though, as even with Natural yoghurt, his poos aren't great. I wish that the manufacturers made 400g bags of prescription dry foods, then I Could try him on a sensitivity one. I have tried him on Purina One, as Molly can tolerate that more than any others, but he is still dodgy on that. Fortunately, I only got him one box of dry food cos it was on offer, must donate it to the rescue soon.
