Pinky, did you noticed this started with the Ultra chicken formula? When you started the meds did you still give the dry food? Don’t give any dry food until you see a solid stool. Give the homemade I mentioned. When you see a solid stool for a few days than give the new dry slowly, which ever one you choose. The system needs a rest from dry food for a few days. Mucus sometimes means a food intolerance or an irritation. I would stay away from the Ultra chicken formula you were using. I feel bad for you and the dog, I am trying my best to give you the best advice I know. I hope your dog gets better. Please let me know how it turns out.
