PURINA® PRO PLAN® FortiFlora® is a probiotic complementary feed that supports the digestive health and overall wellbeing of dogs and puppies. It effectively helps balance the intestinal microflora and supports the immune system, especially when a dog has digestive upset caused by stress, antibiotics or a change of food. FortiFlora® can help improve stool quality, reduce digestive upset and act as an appetite enhancer for dogs with a poor appetite. Consult your vet before use.
