Metabolic Weight Helps Predict a Dog’s Daily Food Needs

Adult dogs can vary in size from 2 pounds to 250 pounds1.  So, with such a huge range of sizes, how can you figure out how much food your dog needs?

OK… time to get a little technical.

First, it’s important to know your dog’s energy requirements are not linearly proportional to his body weight.

In other words… they’re not related to each other… in a straight line.

A dog weighing fifty pounds does not necessarily use five times more energy than one weighing just ten.

No… a dog’s energy requirements are not linearly related to his body weight.  They’re related to his metabolic weight… the virtual weight of his energy-using tissues… his muscles, his organs, and so on.

Of course… energy needs are also related to a dog’s activity level… how much he uses those tissues, too.  Is your dog active… or inactive?  Is he a puppy… an adult… or a senior?

An internationally respected veterinary research institute has developed a formula that uses a dog’s metabolic weight to scientifically determine his energy needs2.
