Since 1968 Royal Canin has worked to make nutrition cats and dogs first medicine. It is our way of making a better world for pets. It took us 10 years of research to come up with the first diagnostic tool diet designed for dogs with allergic reactions. This diet is a breakthrough nutritional solution that supports pets with extreme food allergies. Made with extensively hydrolysed proteins (oligopeptides), this kibble can be easily digested without being detected by overly sensitive immune systems.
