Best Meals to Fatten Up Dogs Healthy Weight Gain Foods for Underweight PetsSome dogs struggle to gain weight, whether due to high energy levels, health issues, or being naturally lean. If your dog is underweight, it’s important to choose nutritious meals to fatten up dogs safely and effectively. Helping your dog gain weight isn’t just about feeding more it’s about feeding right. This guide will walk you through high-calorie dog meals, homemade options, and safe weight gain strategies.
When Should You Fatten Up a Dog?
Not all skinny dogs need more weight. Some breeds, like Greyhounds or Whippets, naturally appear lean. But if your dog’s ribs, spine, or hips are clearly visible and there’s little fat coverage, your pet may be underweight.
Reasons to help a dog gain weight include
-
Recovery from illness or surgery
-
Rescuing an emaciated dog
-
Dogs with high energy needs
-
Picky eaters or poor appetite
If you’re unsure, consult a vet to rule out underlying issues like parasites, diabetes, or thyroid problems.
General Principles for Healthy Dog Weight Gain
Before changing your dog’s diet, remember these core tips
-
Gradually increase calorie intake
-
Focus on nutrient-rich meals, not just fats
-
Split meals into smaller, more frequent portions
-
Ensure proper hydration
-
Monitor weight and behavior changes weekly
Now let’s look at the best meals and ingredients to help fatten up your dog safely.
High-Calorie Ingredients to Add to Your Dog’s Diet
These calorie-dense foods can be added to your dog’s current meals to boost nutrition and support weight gain
1. Lean Meats
Cooked chicken, turkey, or lean beef provide high-quality protein and fat without excessive grease. Avoid adding seasoning or sauces.
2. Eggs
Eggs are a great source of protein, vitamins, and healthy fats. Cook them thoroughly before feeding to avoid salmonella.
3. Peanut Butter
Dogs love peanut butter, and it’s rich in fat and calories. Choose a variety without xylitol, a sweetener that is toxic to dogs.
4. Pumpkin and Sweet Potato
These ingredients are gentle on the stomach and full of fiber and calories. They also support healthy digestion.
5. Oatmeal
Cooked plain oatmeal can be mixed with other foods for added carbs and bulk. It’s ideal for dogs needing slow-releasing energy.
6. Coconut Oil or Fish Oil
Both can boost calories and improve coat condition. Use small amounts to avoid stomach upset.

If you prefer to prepare your dog’s food at home, here are a few homemade weight-gain recipes that are simple and effective.

2 cups cooked chicken (shredded)
-
1 cup cooked white rice
-
1/2 cup sweet potato (mashed)

Recipe 2 Beef and Oatmeal Energy Bowl

1 cup pumpkin puree

1 tsp fish oil
This mix supports digestion while delivering calories and essential nutrients.
High-Calorie Dog Foods Available Commercially
If you prefer packaged food, look for labels that say ‘high-performance,’ ‘working dog,’ or ‘puppy formula,’ as they typically contain more calories.
Look for these traits in high-calorie dog food
-
Over 400 calories per cup
-
Protein above 25%
-
Healthy fats around 15-20%
-
No artificial fillers
Mixing dry kibble with wet food or meal toppers can further increase calorie content and make meals more appealing.
Tips to Encourage Eating in Underweight Dogs
Sometimes, getting a skinny dog to eat more is half the battle. Try these simple methods
-
Feed small meals multiple times a day instead of one or two large meals
-
Warm up the food slightly to enhance aroma
-
Use bone broth to moisten dry kibble
-
Add tasty toppers like grated cheese or plain yogurt
-
Provide a quiet space for your dog to eat without distractions
If your dog refuses food entirely, seek veterinary advice right away.
Supplements to Support Weight Gain
There are also canine weight-gain supplements that contain vitamins, amino acids, and calories in one formula. These can be useful if your dog is very underweight or recovering from illness. However, they should be used alongside regular food, not as a replacement.
Popular supplement forms include
-
Powdered meal enhancers
-
Liquid nutritional boosters
-
High-protein treats
Always follow dosage instructions and monitor how your dog responds.
Breeds That May Need More Calories
Some dogs naturally require more calories to maintain a healthy weight. These include
-
Working dogs like Huskies, Border Collies, and Belgian Malinois
-
Sporting breeds like Pointers and Setters
-
Large breeds with fast metabolisms
-
Puppies and adolescent dogs
-
Nursing mothers
Tailoring your dog’s meals to its lifestyle and breed type is important for steady weight gain.
What to Avoid When Feeding for Weight Gain
Not all food is good for weight gain. Avoid
-
Fried or greasy foods
-
Excessive human table scraps
-
Sugary treats or baked goods
-
Overfeeding in one sitting
-
Sudden diet changes without transition
These can lead to digestive problems or cause unhealthy fat gain rather than muscle development.
How to Monitor Progress
Weigh your dog once a week using a pet scale or by visiting a vet. Keep track of
-
Weight changes
-
Energy levels
-
Appetite
-
Stool quality
-
Coat and skin health
Gaining weight should be gradual and steady. Rapid changes can stress the body or point to other problems.
Feeding the right meals to fatten up dogs is a safe and effective way to help your pet thrive. With a mix of high-calorie ingredients, nutritious recipes, and supportive feeding habits, your underweight dog can return to a healthy condition.
Remember to be patient, consistent, and responsive to your dog’s individual needs. Weight gain doesn’t happen overnight, but with the right diet and care, your furry friend will be on the path to better health and happiness.
