We have strict specifications for the ingredients we use in our pet foods. We only purchase ingredients from suppliers that meet our rigorous approval process. All our pet foods must meet strict digestibility targets. One of the most visible signs of health in a dog is their faeces. When a pet has diarrhoea it is concerning to the owner, and the cause is often linked to the food the pet is eating. However, diarrhoea is far more likely to be a result of illness, stress, or eating prey (wild mice or birds), human foods or foods found in bins or on the street. Changing your dog's diet too quickly is another common cause of diarrhoea. Remember that if you're switching your dog from one food to another, you'll need to do it gradually over a period of around a week.
