Being overweight puts your dog at risk for developing a serious health complication, like diabetes, arthritis or heart disease. Along with exercise, a diet consisting of higher protein and lower fat can help a dog lose weight. Most dogs need about 25–30 calories per pound per day to maintain their weight. For example, a 30-pound dog needs around 800 calories a day. You can subtract from this figure to help your dog lose weight.

What is the best dog food for weight loss?

There are a variety of dog foods on the market advertised to promote healthy weight in dogs. We’ve selected five of our top picks to highlight below. Each of these recipes includes a low-fat diet, with little-to-no artificial, synthetic or filler ingredients for a healthy, balanced meal. Consider adopting a grain-free diet for your dog if are concerned about them filling up with fillers instead of real ingredients.

How to tell if your dog is overweight

If you’re not sure your dog is overweight, consider using a body condition score for dogs, which is similar to a BMI for people. Ideally, your dog will land in the middle of the score. Check to see if you can feel your dog’s ribs. You should also be able to distinguish between your dog’s chest and stomach. Overweight dogs also might breathe heavier when walking, move slower or sleep more often.  

How much should my dog weigh?

Not all dogs are the same. Your dog's ideal weight depends on several factors, including breed, gender and height. Here's a look at healthy weights for the country's top 10 dog breeds.

How to help a dog lose weight

More than half of dogs in the United States are overweight, according to research from Banfield Pet Hospital. Since 2007, the number of overweight canine pets has increased a staggering 158 percent. When dogs are heavier than they should be, they are more prone to suffer from conditions such as heart disease, arthritis and diabetes, as well as a lower life expectancy. Luckily, there are ways to help your dog return to a healthy weight:

  1. Increase your dog’s daily exercise
    Almost every dog stands to benefit from 30 minutes to two hours of physical activity every day. Often, a casual walk around the neighborhood will suffice.
  2. Decrease your dog’s food portion size
    Instead of feeding once or twice a day, feed your dog smaller portions multiple times a day to keep blood sugar levels steady. Keep water available to your dog all day, but don’t leave food out after more than 15 minutes since dogs can’t self-regulate.
  3. Feed your dog weight management dog food
    Buying the best diet dog food for your pet’s nutritional needs is another important way to keep your dog’s weight under control. Look for a formula that offers more protein and less fat with a reduced calorie count.

By making a few simple changes, you can help your dog lose weight and live a healthier, happier life.
