How Many Calories Should My Dog Eat? How To Calculate the Right Intake

We have more in common with our furry friends than we might think at first glance! Just like human beings, every dog needs a unique-to-them calorie intake. This can fluctuate based on a variety of factors, so it’s important to look holistically at your dog’s activity level, age, size, and other characteristics to determine how many they’ll need.


It can be rather formulaic when it comes to calculating the right amount of calories for your pet. But figuring out exactly how much your dog needs to eat better equips you to feed your pet the right amount of food.


When your dog doesn’t get the right amount of food, you might notice that they don’t act like themselves, or that they’re otherwise unwell. This could be due to a lack of necessary nutrients. In addition to having the right amount of calories, it’s also essential that your pet has the right type of calories. This means feeding them food that bolsters their overall health, not food that slows them down.


If all of this sounds like a lot to take into account, that’s because it can be! Luckily, we’re here to walk you through everything you need to know regarding your dog’s calorie intake.



A General Formula Used By Some Veterinarians 


There’s actually a direct mathematical way to figure out how many calories your dog needs to eat. Some veterinarians use this formula to help their clients figure out how much their pups should consume. Following a formula like this is more valuable than using a rough estimate. 


This is because there are a variety of different factors that can contribute to how many calories your dog should eat. Using a general number doesn’t consider those unique, specific factors. In order to calculate the number of calories your dog needs to eat, you can utilize this formula. Please note that this is used only to determine your dog’s maintenance energy requirements. Dogs who need to gain or lose weight require a different approach.


First, divide your dog’s weight (in pounds) by 2.2 to convert it to kilograms (kg).


Next, we’re going to find the Resting Energy Requirement, also known as RER. To do this, use a little multiplication: 70(weight in kg)^0.75


To get Maintenance Energy Requirement (or MER) = the appropriate multiplier x RER


Some appropriate multipliers include: 

  • A typical, neutered dog: 1.6
  • Loss of weight: 1
  • Weight gain: 1.7 
  • Light work or activity: 2 
  • Moderate work or activity: 3 
  • Heavy work or working-dog: 6 
  • Puppy under four months old: 6 
  • Puppy more than four months old: 2


Once you’ve completed this formula, you’ve figured out what your dog needs per day. Congrats! You’re one step closer to helping ensure that your dog gets the calories they need to live a fulfilling, healthy life. 



What’s Maintenance Energy? 


You saw the term ‘maintenance energy’ in the above formula, so you might be wondering what exactly that means. We have a definition that you can use to help you better understand. 


When we talk about maintenance energy, we’re referring to how much energy your pup requires for basic metabolic functions. In addition to that, it also refers to how much is needed to maintain body weight. This, again, demonstrates the necessity to provide your dog with the correct amount of calories. The above formula specifically sheds light on this because serious problems could arise if your pet’s calorie intake isn’t high enough.


If your dog isn’t getting enough calories, their body won’t be able to keep up with basic functions. This could ultimately contribute to the detriment and decay of their body long-term. 



 Factors That Affect Caloric Needs


As we mentioned earlier, caloric needs are certainly not one-size-fits-all! That means that there are a multitude of factors that contribute to how many calories your pet needs to eat every day. We’ll run through some factors that can impact your pet in this way. 



Neutered vs. Not Neutered 


The first factor you should take into account when determining your pet’s caloric requirements is if they’re neutered or not. When your pet gets neutered, they’re at what can be referred to as a “nutritional milestone.” This means that if you don’t make an adjustment to their food intake, they’re going to gain weight. This is because getting your dog neutered causes a decrease in estrogens and androgens. The result? A lower metabolic rate. Therefore, your pet is going to have lower energy needs than they did before. That’s why it is essential that you re-evaluate your pet’s dietary habits after they get this procedure done. 



Dog’s Body Condition


Your dog’s body condition also contributes to their caloric needs. As your dog grows, develops, and ages, their body is going to change. As a result, so will the number of calories that they need to eat. Puppies require more protein than adult dogs do, so changing your dog’s food from puppy to adult will impact how many calories they consume. 


Similarly, senior dogs also have different calorie needs than young or adult dogs. Some dogs that are entering their senior years could benefit from having food with fewer calories and less fat. A recent study demonstrated older dogs require 20% fewer calories to upkeep their weight than younger dogs do. This could possibly be attributed to activity levels. 


Activity Level 


Finally, you should take your dog’s activity level into account when you’re deciding how many calories they may need to eat. If your dog is highly active, they’re inevitably going to need more calories than one that doesn’t move a majority of the day. 


You can figure out how your dog’s individual activity level factors into how many calories they need to eat by utilizing the aforementioned formula. An option for multipliers includes activity level, so by substituting in the number associated with how active your dog is, you can gain a more robust understanding of their needs. 



Calories Depend on Food’s Nutrient Profile, Too


We’ve said this before, and we’ll say it again: it doesn’t matter if you’re giving your dog the right amount of calories if you’re giving them food that isn’t healthy for them. Too many dog foods contain products that you would never intentionally serve your furry friend. 


Many dog food brands sneak by with vague ingredients such as “meal meat.” But do you know how many calories these “foods” are providing your dog? What about the nutritional benefits they have—if any? 


When you take time to investigate your dog’s food, you’ll be shocked at how many products are created without your pet’s health in mind. Finding the right food for your pup requires a discerning eye and a willingness to dig deeper and figure out what’s really going on beyond the glossy food bag label.
