Being a Real Dog for large breeds means running around and chasing for some, and protecting and guarding for others. Either way - they need a food that can properly fuel their natural enthusiasm for life. That is why our Purina BETA tailored nutrition for large breed adult dogs includes essential amino acids to help support vital organ functions including the heart, and omega 3 fatty acids to help support healthy joints. It is also specially formulated with selected natural ingredients and a natural prebiotic to help support digestive health, which also helps them to be at their best! And all this without including any added artificial colours, flavours or preservatives.
