Jack Russell Terrier Nutritional Requirements
Jack Russell Terriers are a small-sized, very high-activity breed with specific nutritional needs that must be carefully balanced. One of the most energetic small breeds with caloric needs approaching those of much larger dogs. Burns enormous amounts of energy through constant activity. If exercise is restricted (injury, age), caloric reduction is critical to prevent rapid weight gain.
