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 Purina BETA tailored a nutritional food for large breed adult dogs which 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.
