How much should a 40 pound dog eat a day? Simple and Effective Tips

How Much Should My Dog Eat?

How much should a dog eat a day? The truth is, there is no one-size-fits-all answer. There are numerous concerns that factor into how much and how often dogs should eat, and each pup has their own unique needs. It’s hard for humans to tell exactly what their dogs crave, and it doesn’t help that they like to make us think they’re always hungry (and we get it – those faces are hard to ignore!).

Getting your dog on a proper feeding schedule is crucial to their health, like pet insurance. Too little food each day can cause them to be deficient in vital nutrients that help keep dogs healthy. But too much, and your dog is at risk of becoming obese – and obesity comes with its own set of health risks for pets. The best way to ensure your dog is eating properly is to put them on a regimented schedule of the perfect amount of healthy foods.

What Factors Impact How Much to Feed a Dog?

Several factors can impact not only how much food to feed your dog, but also what type of food he needs.

  • Weight: Maintaining an ideal body condition is important for your dog’s overall health. “If your dog is not his ideal body condition, you may need to make adjustments in what and how much you are feeding him,” says Dr. Callie Harris, DVM. Consider a weight management formula to help your dog achieve and maintain his ideal body condition. We also recommend working with your veterinarian to rule out any health concerns.
  • Activity Levels: The feeding recommendations on dog food packages are based on average adult dogs with normal activity levels. If your dog gets a lot of daily exercise by going on daily runs or hikes with you, he may need more calories to meet his energy needs. “Dogs who are less active and overweight may need a more managed daily caloric intake,” according to Dr. Harris.
  • Age: As your dog grows, his nutritional needs change. If your dog is still a puppy, he needs a puppy food for growth and development. Seniors may benefit from senior formulas that help keep older dogs active and their minds sharp. Work with your veterinarian to determine the type of food your dog needs based on his life stage and life style.
  • Once you find a complete and balanced food that meets your dog’s individual needs, you can determine how much food to feed him. The dog feeding chart on the back of his dog food package can help guide you.

    Dog feeding charts are required on dog food packaging. The layout of the chart, however, can vary from brand to brand.

    If you’re switching brands, pay close attention to ensure you’re feeding your dog the correct amount based on his age and weight.

    According to Dr. Harris, “Dog feeding charts usually make recommendations for daily intake. So, if you’re feeding your dog more than once a day, you’ll need to divide the amount recommended in the chart between those meals.”

    Here’s a sample dog feeding chart similar to the one you will find on any dry dog food packaging:

    Adult Dog Size (lbs) Dry Food Feeding Amount (Cups)
    3 to 12 1/3 to 1
    13 to 20 1 to 1/3
    21 to 35 1-1/3 to 2
    26 to 50 2 to 2-2/3
    51 to 75 2-2/3 to 3-1/3
    76 to 100 3-1/3 to 4-1/4
    100+ 4-1/4 plus 1/4 cup for each 10 lbs of body weight over 100 lbs

    Note: Dog feeding amounts vary from product to product based on calorie content and formula. Consult the feeding chart on the back of your dog’s food packaging. Individual needs can vary, so consult your veterinarian regarding special dietary needs.

    How Much Should Dogs Eat Based on Weight

    The simplest way to gauge how much your dog should eat each day is measuring out their food based on their body weight. Naturally, smaller dogs need less food than larger ones, but what exactly is the perfect number?

    First, it’s important to have an accurate handle on how much your dog weighs and whether their body size is considered small, medium, or large. Not having a grasp on your dog’s weight could cause you to easily under or overfeed your pet.

    Below is a recommended feeding schedule for how much and how often dogs should eat a day, based on their weight:

    Most pet lovers can spot a toy dog when they see one because, despite their tiny stature, toy dogs have big personalities that always seem to stand out from the crowd. But what exactly constitutes a dog as being a “toy” breed?

    Some examples of toy breeds: Pomeranian, Havanese, and Yorkshire Terriers. As a rule of thumb, most toy breeds weigh around 10 pounds.

    Toy breeds should eat:

  • 1/3 cup per day if they weigh 3 pounds
  • 1/2 cup per day if they weigh 6 pounds
  • Though the line between toy and small breeds is blurred, it’s important to know the difference to make sure you’re giving your pup a proper dog diet. Most dogs that are generally larger than a toy, but still around 20 pounds, are considered small breeds.

    Boston Terriers, Dachshunds, Shih Tzus, and Pugs can all be considered small dogs.

    Small breeds should eat:

  • 3/4 cup per day if they weigh 10 pounds
  • 1 cup per day if they weigh 15 pounds
  • 1 2/3 cups per day if they weigh 20 pounds

    Medium breeds often require a bit more food than their small friends. Though the term “medium dog” seems a little vague, there are actually quite a few popular breeds that claim the title.

    A few examples of medium dog breeds: Australian Shepherd, Bull Terrier, and Collie.

    Medium breeds should eat:

  • 1 3/4 cups per day if they weigh 30 pounds
  • 2 1/4 cups per day if they weigh 40 pounds
  • 2 2/3 cups per day if they weigh 50 pounds
  • Let’s face it: large dogs are easy to spot. And though they can weigh up to ten times more than toy breeds, large pups often like to act like lap dogs anyway. It shouldn’t come as a surprise that these gentle giants put away a lot of food each day.

    German Shepherds, Golden Retrievers, Rottweilers, and Bernese Mountain Dogs are all considered large breeds.

    Large breeds should eat:

  • 3 cups per day if they weigh 60 pounds
  • 3 1/2 cups per day if they weigh 70 pounds
  • 3 3/4 cups per day if they weigh 80 pounds
  • 4 1/4 cups per day if they weigh 90 pounds
  • 4 1/2 cups per day if they weigh 100 pounds
  • Note: Add in an extra 1/3 cup for every 10 pounds if your dog weighs over 100 pounds.
