How the Formula Works
Our calculator uses the standard veterinary formula for Resting Energy Requirement (RER) and Maintenance Energy Requirement (MER).
- RER = 70 × (Body Weight in kg) ^ 0.75
- MER = RER × (Multiplier based on life stage, activity, and neuter status)
Wet vs Dry Food: Which is Better?
Choosing between wet and dry dog food often depends on your dog's specific needs, preferences, and your lifestyle. Both have their advantages:
- Dry Food (Kibble): Highly convenient, easy to store, and generally more affordable. The crunchy texture can also help reduce plaque and tartar buildup on your dog's teeth. It's energy-dense, meaning a smaller volume provides more calories.
- Wet Food: Contains much higher moisture content, which is excellent for hydration, especially for dogs prone to urinary tract issues or those who don't drink enough water. It's typically more palatable and aromatic, making it a great choice for picky eaters or senior dogs with dental problems.
- Mixed Feeding: Combining both wet and dry food can offer the benefits of both—the crunch of kibble for dental health and the moisture and palatability of wet food. Just be sure to calculate the total calories correctly to avoid overfeeding.
Feeding Guidelines and Best Practices
Proper feeding goes beyond just measuring calories. Here are some essential guidelines to keep your dog healthy:
- Establish a Routine: Feed your dog at the same times each day. This helps regulate their digestion and makes potty training easier.
- Measure Portions Accurately: Use a standard measuring cup, not just a random scoop or mug. Overfeeding even by a little bit each day can lead to significant weight gain over time.
- Monitor Body Condition: Regularly assess your dog's Body Condition Score (BCS). Adjust their food intake if they start gaining or losing weight unexpectedly.
- Limit Treats: Treats should never exceed 10% of your dog's daily caloric intake. Choose healthy options like small pieces of carrot or apple.
- Transition Slowly: When changing dog food brands or formulas, do it gradually over 7-10 days by mixing the new food with the old to prevent gastrointestinal upset.
