How To Put Weight On A Dog?

Just like the process of losing weight can take months, healthy weight gain won’t happen overnight. To put on some extra pounds, your dog should ingest more and burn fewer calories.

Smaller meals

For healthy weight gain, you should feed your dog more frequently with smaller meals. Eating smaller meals will prevent digestion problems. Also, it’s a healthy way of including more calories in your dog’s diet.

High calorie treats and supplements

Include high-calorie treats and supplements into your dog’s balanced diet. Make sure that the dog treats are full of proteins and fats to speed up the weight gaining process.

Puppy food

A high-calorie supplemental canned food for puppies can be a good way of including more calories into your dog’s diet. Just make sure that your dog needs that amount of calories, since eating this type of food can cause obesity.

How to find the best dog food for weight gain?

If you think that your dog looks skinny, talk with your veterinarian before you start searching for the best dog food to gain weight. Some dogs are naturally picky eaters, or their current diet doesn’t provide sufficient nutrients. However, sometimes a dog’s weight loss is caused by some disease.

How can you tell if your dog is underweight?

The easiest way to know for sure is to look at his body carefully. For dogs who have a longer coat, you can feel by touching them and they present some of these signs:

  • You can easily feel or see your dog’s ribs, pelvis, and hips
  • Their coat’s in poor condition
  • Lack of energy
  • Depression
  • Poor eating habits

If your dog is presenting some or all of these signs, take him to the veterinarian. Your vet can measure his exact weight and run necessary tests to exclude diseases.

What can cause lower than normal body weight?

There are many reasons for a dog to be underweight. Some of them are not medically related. In these situations, specific dog foods can help them gain weight/muscle and get your pooch on their feet. Remember, your pooch first needs to go to the vet

Things attributed to your dog’s weight loss are:

  • Excessive exercise: Some dogs lose weight because they are highly active and don’t eat the right quality of food that contains all necessary nutrients.
  • Picky eater: Some dogs don’t like the food you are giving them. Until you find the taste that they love, they’ll refuse to eat anything.
  • Old age: When dogs get older, they tend to lose weight and muscle tissue. If this has happened to your dog, it’s best to pick dog food that is rich in protein and calories.
  • Health issues: Some of the most common diseases associated with weight loss in dogs are: dental problems, gastrointestinal problems, diabetes, internal parasites, and cancer.

What are the nutritional needs of an underweight dog?

If you start feeding him with the more substantial amounts of his regular food, your skinny dog will not gain weight. Instead, dog food for a healthy weight gain should be easy to digest, have high levels of meat-based protein and more significant amounts of fat.

When you are researching high calorie food brands check if their formula has these things:

  • Higher caloric value than regular dog food
  • Has around 30% protein and 20% fats
  • Meat should be the main ingredient
  • Is grain-free or contains healthy whole grains
  • Doesn’t contain preservatives, artificial colors, or flavors
  • Contains all vitamins, minerals, and antioxidants

For dogs that only need to gain a little extra weight, there are also options for an excellent high-calorie dog food supplement. These contain vast amounts of calories. Most common are liquids that you mix with food and water or edible gels.


Remember that lower than average weight in dogs is a symptom and not a disease. Common diseases associated with weight loss are dental problems, cancer, gastrointestinal problems, and diabetes.
