HoundGames Launches Most Accurate Dog Feeding Calculator Using RER Method

“We wanted to create a more accurate dog feeding calculator, which also included mixed breed dogs, like our Cavoodle, Bobby,” said Geoff Boileau, co-founder of HoundGames. “We look forward to helping dog owners with the sometimes difficult task of knowing how much to feed their dog.”

Dog feeding calculators primarily use a dog’s ideal weight to determine the calories needed. The problem is, mixed breed dogs don’t have ideal weight, and while in a perfect world all dogs in a breed are uniform in size, that just isn’t the case.

For example, take two Border Collies. One is large for his race and the other is small for his race. If we gave them the “ideal” calorie intake for their breed, we would not get enough and we would get too much.

Instead, a more accurate measurement is obtained through the use of RER or resting energy requirements. RER is the amount of energy needed to maintain a dog’s basic bodily functions, such as breathing, heart function, and brain function.

The RER is calculated using this formula found on the Ohio State University of Veterinarian Medical Science website: Take the Weight of a Dog. If it is in pounds, divide that number by 2.2046. This gives the dog’s weight in kilograms. This figure is then multiplied by the weight in kg of the dog raised to the power ¾ by 70.

To then accurately calculate a dog’s daily energy requirement (or DER), other factors are taken into account.

For example, a puppy needs 3X the RER to account for its growth rate. A neutered adult dog needs 1.6 times the energy requirement at rest. A working dog would also require a higher multiple of the RER.

This multiplied RER produces the kcal needed to reach the DER for that specific dog and not for its breed. This means that it is not a guess based on historical data on race or other outside factors. It is based on the weight of each dog and takes into account their life situation.

After having multiplied the RER (depending on the dog’s situation), the owner of a dog now has a kcal figure which represents his dog’s daily energy requirement. This daily kcal requirement is then divided by the kcal per cup found on the back of the kibble package.

The dog owner now knows how many cups of purchased dog food are needed to feed his dog for his energy needs. HoundGames has simplified this calculation process by creating an easy-to-use dog feeding calculator.

After reaching the number of cups needed to feed their dog, the owner then monitors their dog’s weight and uses a Body condition score chart to determine when their dog’s ideal weight has been reached.

For more complex life situations, such as an overweight neutered adult working dog, a visit to a veterinarian is recommended for professional personalized advice. However, for the majority of dogs, the HoundGames RER Dog Feeding Calculator can make a complex task easier and provide a good starting point for feeding dogs.
