Canine Weight Management & Portion Control
Canine obesity is a leading health issue that reduces your pet's life expectancy and increases their risk of arthritis, diabetes, and cardiovascular diseases. Managing your dog's weight is crucial for their longevity.
A safe weekly weight loss rate for dogs is 1% to 2% of their starting body weight. Lowering weight too quickly can lead to hepatic lipidosis and nutritional deficiencies. Adjusting daily calories and feeding measurements is the primary way to manage weight.
This calculator estimates your dog's daily calorie requirements based on their weight and activity level, providing feeding portion guidance to help them return to a healthy weight range.
