“Different pre-biotics and pro-biotics can cause stomach upset when mixed. Each dog food manufacture uses different pre-biotics and pro-biotics. It is best to switch over without a transition period and reduces the risk of stomach upset. Most dogs transition without problems. If stomach upset or loose stool is present, pure pumpkin will calm the digestive upset. This can be used if it is a straight switch over as recommended or a gradual switch.”
