Maintaining a healthy digestive system is critical to ensure your dog absorbs the correct nutrients to continue to grow and develop. Digestive upsets can be caused by a sudden change in diet, poor diet, presence of intestinal worms, and ingestion of foreign material or illness. These upsets can lead to problems such as diarrhoea and flatulence which can be unpleasant and embarrassing for both dog and owner. Probiotic products like Protexin can assist in restoring the good intestinal bacteria after a digestive upset.
