Is your dog underweight, and you are wondering how to help them gain weight the healthy way? You are not alone. Many pet parents worry about this, especially when their dog looks lean, skips meals, or burns energy too quickly. In this guide, you will find 11 safe, nutrient-rich dog foods for weight gain, along with simple tips you can start using today.
1. Farm Fresh Meats and Meals
-
Grilled Chicken with Five Veggies: Chicken gives high-quality protein that supports muscle growth. AAFCO sets the minimum dietary protein requirement for adult dogs at 18% on a dry matter basis (Source: Association of American Feed Control Officials, via PetMD) — a useful baseline for why protein-forward meals like this one matter for dogs trying to rebuild muscle, not just add fat. The veggies add vitamins and steady energy. This meal works well when you want bold dog food for weight gain without heavy fillers.
-
Braised Lamb and Pumpkin: Lamb gives more calories per gram than chicken and supports healthy weight gain. A 100g serving of cooked lamb provides around 283 calories compared to roughly 165 calories for the same amount of cooked chicken breast (Source: USDA nutrition data), which is exactly why it's a denser option for dogs that need extra calories without eating noticeably more food. Pumpkin keeps digestion smooth. This combination suits dogs that need gentle support and a better appetite. It fits perfectly when you look for dog food to put on weight that feels balanced.
-
Farm Fresh Chicken Meat: Fresh chicken provides amino acids and moderate fats that help your dog gain lean weight. The taste stays familiar, and most dogs enjoy it without effort. As a practical guide, a healthy dog generally needs around 1 gram of protein per pound of ideal body weight each day (Source: PetPlace, veterinary nutrition guidance), which makes a protein-dense meat like chicken an easy way to hit that target. This makes it ideal when exploring bold dog food for weight gain that stays simple and clean.
-
Farm Fresh Lamb Kidney: Organ meats are rich in nutrients such as iron, B vitamins, and natural fats. These support metabolism and healthy weight gain. A 100g serving of cooked lamb kidney contains around 12.4mg of iron and nearly 79 micrograms of vitamin B12 (Source: USDA-derived nutrient data) — both far above what a similar serving of muscle meat provides, which is part of why organ meat is considered so nutrient-dense per bite. Lamb kidney works especially well for dogs that refuse bulky meals. It adds a nutrient punch and naturally falls under dog food for weight gain due to its density.
2. Dehydrated Treats and Protein Boosters
-
Dehydrated Sardines: Sardines give natural omega-3 fats and good calories. The oils support skin health and improve energy levels. A 100g serving of sardines provides roughly 208 calories (Source: American Kennel Club, via SafeFoodForDogs), and a typical 3oz canned serving carries around 1,800mg of combined EPA and DHA omega-3s (Source: Canine Arthritis Resources & Education) — among the highest of any commonly fed fish. They work great as meal toppers. If your dog needs ongoing omega-3 support beyond weight gain, our guide on Is Fish Oil Good for Dogs? covers dosage and safety in more depth.
-
Dehydrated Chicken Feet: Chicken feet offer natural collagen and healthy fats. They help dogs maintain joint comfort and add extra calories. Roughly 70% of the total protein in chicken feet comes from collagen (Source: nutrition research cited by Healthline and IPB University), which is why they're often recommended alongside joint-support routines, not just as a calorie booster. They also make meals more exciting for picky eaters.
-
Dehydrated Pork Organs Mix: Pork organs support strong muscles and better stamina. They provide energy without artificial ingredients. This makes them a strong choice when you're looking for the best dog food for weight gain that delivers results through natural nutrition.
-
Dehydrated Chicken Cookies: Chicken cookies offer a crunchy protein boost. You can give them between meals or crumble them over food. They increase calorie intake in a simple and fun way.
3. Nutritious Broths and Meal Enhancers
-
Rich Blend Broth: This broth boosts hydration and improves appetite. It also adds minerals and natural flavour. Warm broth helps dogs eat better, especially during low appetite days - we cover the hydration side of this in more detail in 10 Healthy Liquid Dog Food Options Your Dog Will Love.
-
Chicken Bone Broth: Bone broth supports gut health and joint strength. Traditionally made bone broth typically carries about 6 to 12 grams of protein per cup, mostly from collagen and gelatin released during slow simmering (Source: nutrition analyses from Bare Bones and Bluebird Provisions). It also makes meals softer and easier to finish.
-
Mutton or Lamb Bone Broth: Mutton or Lamb broth offers a richer flavour and denser nutrients, in keeping with lamb's generally higher calorie and fat content compared to chicken. It lifts calorie intake and suits dogs that enjoy stronger tastes. You can use it when you want good dog food for weight gain support without stressing the stomach - browse our full Broths range to compare options.
4. Smart Tips to Use These Foods Safely
-
Increase calorie intake gradually. Aim for about 10-15% extra intake per meal so your dog's system adapts.
-
Divide the total food into 3-4 small meals a day. Frequent meals help dogs digest better and reduce the risk of an upset stomach.
-
Monitor weight weekly using a body-condition score. Vets commonly use the WSAVA's 9-point Body Condition Score scale, where a score of 1 to 3 indicates a dog is underweight and 4 to 5 is considered ideal (Source: World Small Animal Veterinary Association Global Nutrition Committee). Use a trusted scale or vet visit to check progress.
-
Always ensure fresh water is available, especially with rich proteins, organs, and broths.
