How much should I feed my Jack Russell Terrier?

Look for foods that list real meat as the first ingredient, meet AAFCO standards, and address Jack Russell Terrier-specific health needs like luxating patella. Brands offering small breed-specific formulas are often a good choice.
Should I feed my Jack Russell Terrier grain-free food?
Primary lens luxation and deafness are the Jack Russell Terrier diseases. Grain-free food does not hold the lens or restore hearing. Keep the dog lean on a complete dog food so the knees and the back stay easy to carry. A grain allergy is uncommon in Jack Russells and needs a veterinary diagnosis.
