Purina is the most recent pet food company to announce a line of breed-specific dog foods; Beta™. Although currently the line is available in Great Britain only, I suspect it's just a matter of time before it's available in the U.S,. as are Eucanuba and Nature's Recipe breed-specific dog foods currently. Royal Canin produces breed specific foods for dogs and cats. The question is: Should your Terrier be fed differently from a Shepherd? Your Maine Coon from a Siamese?
