FAQs
How much should I feed my dog to lose weight?
The amount depends on your dog's current weight, target weight, activity level, and chosen weight loss rate. Our calculator provides a personalized calorie target with a safe 20-30% reduction from maintenance calories.
How long will it take for my dog to reach their target weight?
The timeline depends on how much weight needs to be lost and the chosen weight loss rate. A safe rate is 1-2% of body weight per week. Our calculator estimates the timeline based on these factors.
Is it safe to reduce my dog's calories by 30%?
A 30% calorie reduction is the maximum safe deficit and should only be used under veterinary supervision. Most dogs do well with a 20-25% reduction. Always consult your veterinarian before starting a weight loss program.
What if my dog needs to lose more than 20% of their weight?
Weight loss exceeding 20-30% of current body weight should be done under close veterinary supervision. Your veterinarian can help create a safe, monitored weight loss plan and check for underlying health issues.
How often should I feed my dog during weight loss?
Multiple small meals (2-4 times per day) can help manage hunger and maintain energy levels. Our calculator provides a feeding schedule based on your chosen frequency.
Should I increase exercise during weight loss?
Moderate exercise is beneficial, but avoid sudden increases in activity. Gradually increase exercise along with dietary changes. Consult your veterinarian for exercise recommendations based on your dog's health.
