Q. My King Charles Spaniel began having very yellow, mucousy diarrhea- she is dripping bits- she eats ZD ultra. Could this be guardian? What do I feed
A. It could be Giardia or another illness of the large bowel. Bring your dog to the vet along with a fresh sample of the diarrhea, because if it is a parasite like Giardia, you will need prescription medication to treat it. For now, you can feed your dog white rice mixed with plain boiled chicken. Don't feed this diet for more than a week, unless directed by your vet, because it is not nutritionally balanced for long-term use.
