If your calculator result shows your puppy tracking below the healthy range for their breed and age, the right diet can help close the gap safely. Always talk to your veterinarian before changing a puppy's diet — rapid weight gain can be just as harmful as being underweight, especially in large and giant breeds prone to joint problems.
- Feed a high-quality, age-appropriate puppy food formulated for your breed's adult size.
- Split daily food into three to four smaller meals to support digestion and steady weight gain.
- Avoid table scraps and adult dog food, which aren't calorie- or nutrient-matched for growing puppies.
- Add a vet-approved wet food topper if your puppy is a picky eater or eating too little.
- Rule out parasites or an underlying illness first, since these are common causes of poor weight gain.
- Re-weigh weekly using the calculator to confirm your puppy is trending upward safely.
