Great for our dog Our 20 month old Lab has had stomach issues for about 4 months. The Vet checked for blockage, blood work, xrays. During this time our Vet changed her food to Hills Z/D. It has helped her tremendously. No stomach issues for 2 months now. Cross your fingers! Pet Care has been wonderful. Very helpful when needed. I can reorder online as long as there is a valid prescription on file from our Vet for refills. Highly recommend Hills Z/D, it helped Heidi. by Heidi14 on 07/03/2016 This product is good for dogs with allergies.
