How Much Should I Feed My Dog?
The amount you should feed your dog depends on several factors, including their body weight, age, metabolism, and activity level. Puppies need more calories to support growth, while senior dogs often need fewer calories.
Most adult dogs require between 2 and 4 percent of their body weight in food per day, but this varies depending on the type of food and energy content.
Using a dog feeding calculator provides a much more accurate estimate than general feeding guidelines.
How the Dog Feeding Calculator Works
This calculator uses the official veterinary formula known as Resting Energy Requirement (RER), which calculates the number of calories your dog needs at rest.
It then applies a Maintenance Energy Requirement (MER) factor based on your dog’s life stage and activity level. This method is used by veterinarians worldwide to calculate feeding amounts.
