Why this matters: Spayed/neutered dogs usually need about 20% to 30% fewer calories to maintain a healthy weight due to changes in sex hormones.
Why this matters: We use activity to adjust for lifestyle - lower factors for indoor dogs and higher for active or working dogs.

This estimate shows how many calories your pet should eat each day. It’s based on an ideal weight, reported activity level, and whether your pet has been spayed or neutered. Treats are not included in the total or calories per meal. If you give treats or extra food, be sure to subtract those calories from your pet’s daily total to help prevent overfeeding.

If your pet needs to lose weight, this number should be adjusted downward using a target weight. Always work with your veterinarian before making dietary changes for weight loss.

Important: This tool is provided by the Association for Pet Obesity Prevention (APOP) for educational purposes only and should not be used as a substitute for veterinary care. Energy needs vary depending on your pet’s health status, body condition, age, and activity level. Always review any diet or weight plan with your veterinary team, and do not begin a weight-loss program, restrict calories, or start an exercise routine without your veterinarian’s guidance.
