Buying Guide
Medium Breed Calorie Needs
A 35-lb moderately active medium breed needs 900-1,100 kcal/day. Activity level significantly impacts this — a working Australian Shepherd may need 1,400+ kcal, while a sedentary Bulldog may need only 700-800 kcal.
Protein and Fat Balance
Medium breeds do well with 22-28% protein and 12-18% fat on a dry matter basis. Active dogs benefit from higher fat for sustained energy, while less active breeds need lower fat to prevent weight gain.
Choosing Between All-Life-Stages and Adult Formulas
All-life-stages formulas are calibrated for the highest nutritional requirements and may be too calorie-dense for adult medium dogs. Adult-specific formulas typically provide better calorie control.
Joint Health Considerations
While joint health is most pressing for large/giant breeds, medium breeds can develop hip and elbow dysplasia. Foods with glucosamine and omega-3s provide preventive joint support.
Frequently Asked Questions
What is considered a medium breed dog?
Medium breed dogs typically weigh 20-50 lbs at adult size. Common examples include Bulldogs, Border Collies, Australian Shepherds, Cocker Spaniels, and Basset Hounds.
Should I feed my medium breed dog twice a day?
Yes. Two meals per day regulates blood sugar, reduces gulping, and maintains satiety. Free-feeding tends to lead to overeating and obesity, especially in less active medium breeds.
How do I know if my medium breed dog is at a healthy weight?
You should be able to feel the ribs without pressing hard, but not see them. From above, the dog should have a visible waist. From the side, the abdomen should tuck up. A body condition score of 4-5 out of 9 is ideal.
Is kibble or wet food better for medium breed dogs?
Dry kibble is typically recommended for dental health and convenience. Many owners use primarily kibble with occasional wet food as a topper or treat.
