More Details on Our Top Picks
Hill’s Science Diet Adult Perfect Weight Dry Dog Food, Chicken & Brown Rice, 4 lb Bag
This option stands out for its focus on supporting healthy weight loss while maintaining lean muscle, making it ideal for adult dogs needing to shed weight safely. Compared with Beneful, which emphasizes natural ingredients but lacks clinical backing, Hill’s offers a scientifically supported approach. Its formulation is suitable for all breed sizes, but it requires patience, with results taking up to 10 weeks. The natural ingredients and proven results make it a reliable choice for owners prioritizing health-backed weight control, though those seeking rapid results or specific flavor options may find it limiting.
Pros:- Supports safe weight loss and muscle maintenance
- Clinically proven results within 10 weeks
- Made with natural ingredients
- Suitable for all breed sizes
Cons:- May take up to 10 weeks to see full results

Our verdict“This makes the most sense for owners who want a scientifically supported, gradual weight management solution for adult dogs.”
Pedigree Healthy Weight Adult Dry Dog Food, Roasted Chicken and Vegetable Flavor, 14 lb. Bag
Compared to premium options like Hill’s, Pedigree offers a more budget-friendly approach with a focus on balanced nutrition and added prebiotic fibers for digestion. Its high-quality protein and essential vitamins support overall health, making it suitable for busy owners seeking a nutritious, everyday dog food. However, its lack of detailed ingredient sourcing and limited information on grain content may concern those with specific dietary sensitivities. While it lacks the clinical backing of Hill’s, Pedigree’s generous size and affordability make it a practical choice for owners looking for consistent, healthy weight management at a lower cost.
Pros:- Supports healthy weight management affordably
- Contains 36 essential vitamins, minerals, and amino acids
- Supports digestion with prebiotic fibers

Our verdict“Ideal for owners wanting a cost-effective, nutritious option for maintaining a healthy weight in adult dogs.”
Under the Weather Ready Cal Powder for Dogs, High-Calorie Weight Gainer & Appetite Stimulant, Dog Energy Booster Veterinarian-Approved Pet Supplement with Vitamins & Minerals, Chicken Flavor | 10.58 oz
This supplement excels for dogs that need to gain weight or have poor appetites, offering a concentrated calorie boost with 40 calories per scoop. Its palatable chicken flavor encourages dogs to eat more, and the added vitamins support overall health. Unlike food-only options like Hill’s or Pedigree, this powder is best used as a supplement, making it ideal for owners whose dogs require appetite stimulation or quick weight gain. However, the need for mixing with food or water can be inconvenient, and it’s limited to dogs needing extra calories, not daily maintenance.
Pros:- Promotes healthy weight gain with 40 calories per scoop
- Encourages appetite in dogs with poor eating habits
- Contains essential vitamins and minerals
- Palatable chicken flavor dogs love
Cons:- Requires mixing with food or water, which may be inconvenient
- Only suitable for dogs needing weight gain or appetite support
Best for: Owners of underweight or recovering dogs needing appetite stimulation and calorie boosts
Not ideal for: Pet owners looking for a complete daily diet or with dogs allergic to chicken or powders
- Flavor:Chicken
- Item Form:Powder
- Specific Uses:For Dogs
- Item Weight:10.58 oz
Our verdict“A targeted supplement for dogs needing to boost weight and appetite, best used alongside regular meals.”
PetAg Dyne High Calorie Liquid Nutritional Supplement for Dogs & Puppies, 16 oz, Supports Performance and Endurance, Sweet Vanilla Flavor
PetAg Dyne is designed to provide concentrated energy, making it well-suited for active, pregnant, or underweight dogs needing a performance boost. Its liquid form allows easy administration, either directly or poured over food, and it supports endurance for working or aging dogs. Compared with powdered supplements, its liquid delivery can be more convenient for dogs that resist pills or powders. However, the vanilla flavor may not appeal to all dogs, and it’s primarily beneficial for dogs with specific performance or endurance needs, rather than routine weight gain.
Pros:- Supports performance and endurance in active dogs
- High-calorie, nutrient-dense formula
- Palatable vanilla flavor, easy to administer
Cons:- May not be suitable for dogs with vanilla allergies
- Requires shaking before use
Best for: Owners of active, pregnant, or underweight dogs requiring a performance-oriented calorie supplement
Not ideal for: Dog owners seeking a simple daily diet or with dogs allergic to vanilla flavor
- Flavor:Sweet Vanilla
- Item Form:Liquid
- Weight:16 Ounces
- Volume:16 Fluid Ounces
Our verdict“Ideal for owners wanting to support their active or underweight dogs with a performance boost via a liquid supplement.”
Beneful Healthy Weight Dry Dog Food with Farm-Raised Chicken, 3.5 lb Bags (Pack of 4)
Compared to specialized formulas like Hill’s, Beneful provides a more natural ingredient profile with farm-raised chicken, fruits, and vegetables, targeting weight management with fewer calories. Its high protein content supports muscle preservation, but the added colors from natural sources and limited transparency on sourcing might concern owners seeking stringent ingredient standards. This product makes sense for owners wanting a straightforward, natural-looking diet with a focus on weight control, though it may not be ideal for dogs with sensitivities or allergies to chicken or certain ingredients.
Pros:- Supports healthy weight management
- Made with natural ingredients and no artificial preservatives
- High in protein and essential nutrients
- Includes fruits and vegetables
Cons:- Contains added colors from natural sources
- Limited information on ingredient sourcing
- May not suit dogs with food sensitivities
Best for: Owners seeking a natural, straightforward weight management food for adult dogs with a preference for farm-raised ingredients
Not ideal for: Owners of sensitive dogs with food allergies or seeking detailed ingredient sourcing transparency
- Weight:3.5 lbs per bag
- Pack Size:4 bags
- Calories:10% fewer calories than Beneful Originals
- Protein:25 grams per cup
- Vitamins and Minerals:23
Our verdict“Best suited for owners prioritizing natural ingredients and straightforward weight support for adult dogs.”
Best Breed Dr. Gary’s Working Dog Diet, High Calorie Dry Dog Food for Active & Underweight Dogs, 13 lb Bag
This product stands out for its high calorie density and nutrient-rich formulation, making it an excellent choice for active, underweight dogs needing rapid weight gain. Compared to Purina ONE Plus, which offers balanced weight management without as much focus on calorie density, Dr. Gary’s Working Dog Diet provides more energy per serving—crucial for dogs with high activity levels. Its premium ingredients, including slow-cooked chicken and eggs, support easy digestion and overall health. The main tradeoff is that its calorie-rich profile might be too much for less active or sensitive dogs, and the higher fat content could pose issues for certain health conditions. Overall, this makes the best choice for working dogs or highly active pets needing concentrated calories.
Pros:- High in calories, ideal for weight gain and active dogs
- Made with premium, slow-cooked ingredients for easy digestion
- Formulated for all life stages, including pregnant and nursing females
- Free from GMOs, corn, wheat, soy, and by-products
Cons:- May be too calorie-dense for less active dogs
- Specific dietary needs may require veterinarian consultation
- Higher fat content might not suit certain health conditions
Best for: Active, working, or highly energetic dogs that need to gain weight quickly
Not ideal for: Less active or sedentary dogs, or those with health issues sensitive to high fat intake
- Weight:13 lb
- Calories per cup:580
- Formulation:High fat, moderate protein
- Ingredients:Premium chicken, eggs, omega-3 and omega-6 fatty acids
- Made in:USA
- Suitable for:All life stages, pregnant and nursing females
Our verdict“This is the best pick for highly active or working dogs needing concentrated calories for weight gain.”
Purina ONE Plus Healthy Weight Dry Dog Food, Real Turkey, 8 lb Bag
This option makes the most sense for pet owners seeking a balanced, high-quality dog food that supports healthy weight control without excessive calories. Unlike Dr. Gary’s Working Dog Diet, which is geared toward weight gain, Purina ONE Plus emphasizes maintaining a healthy weight with added joint and immune support. Its inclusion of real turkey and glucosamine benefits muscle health and mobility, especially for dogs prone to weight issues. The main tradeoff is that it provides less calorie density, which may slow weight gain in underweight dogs, making it less suitable for dogs needing rapid weight increase. It’s a good fit for owners wanting a nutritious, everyday diet that balances weight management and health.
Pros:- High-quality protein with real turkey
- Supports weight control and muscle health
- Includes antioxidants and glucosamine for joint and immune support
- Complete and balanced nutrition without fillers
Cons:- May not promote rapid weight gain
- Potentially more expensive than basic brands
- Limited flavor options
Best for: Dogs needing weight maintenance or gentle weight gain, especially less active or middle-aged pets
Not ideal for: Dogs requiring aggressive calorie intake or rapid weight gain strategies
- Weight:8 lb
- Main Ingredient:Real turkey
- Form:Dry dog food
- Purpose:Healthy weight management
Our verdict“Ideal for owners seeking a balanced, nutritious diet that maintains or gently supports weight gain in less active dogs.”
Rachael Ray Nutrish Healthy Weight Adult Dry Dog Food with Real Turkey, Brown Rice & Venison – 4.5 lb
This product is tailored for pet owners wanting a natural, meaty diet that promotes healthy weight and metabolism with added vitamins and L-Carnitine. Compared to Purina ONE Plus, which emphasizes joint and immune support, Nutrish focuses on natural ingredients and metabolic support, making it appealing for health-conscious owners. Its inclusion of real turkey and venison provides variety and high-quality protein, but the smaller size—only 4.5 pounds—limits long-term feeding options. Its higher price point may deter budget-conscious buyers. Overall, it’s a good choice for owners prioritizing natural ingredients and metabolic health in a manageable size.
Pros:- Made with real turkey and venison
- Supports healthy weight and metabolism with L-Carnitine
- Natural ingredients with added vitamins and minerals
- Made in the USA and veterinarian reviewed
Cons:- Limited size options (only 4.5 lb bag)
- May not appeal to dogs with specific dietary restrictions
- Higher price compared to standard brands
Best for: Owners seeking a natural, meat-based diet that supports healthy metabolism and weight control
Not ideal for: Pet owners with budget constraints or those needing larger quantities for multiple dogs
- Weight:4.5 lb
- Main Ingredients:Real turkey, brown rice, venison
- Purpose:Supports healthy weight and metabolism
- Formulation:Natural, veterinarian reviewed
Our verdict“Best suited for owners looking for a natural, meat-centric diet that boosts metabolism and healthy weight control.”
Dog Muscle Gain Power Chews – High Protein Canine Weight Gainer with Multivitamins and Omega-3, Supports Muscle Building, Overall Health, and Energy – Chicken Flavor
This supplement targets dogs needing muscle and weight gain, especially useful for those recovering from illness or with naturally lean builds. Its high protein content, including whey protein concentrate, combined with omega-3 and amino acids, supports muscle growth and recovery. Compared to food-based options like Purina ONE Plus, these chews provide a concentrated protein boost in a tasty chicken flavor, making supplementation easier. However, they require consistent administration and may not be suitable for dogs with chicken allergies. This product is best for owners looking to complement a calorie-dense diet with targeted muscle and energy support.
Pros:- Supports muscle growth and recovery
- Suitable for all breeds and ages
- Delicious chicken flavor dogs love
- Includes essential omega-3 and multivitamins
Cons:- Requires consistent use for best results
- Not a complete diet—must be part of a broader feeding plan
- Potential allergies to chicken
Best for: Dogs needing muscle gain, recovery support, or energy boost, regardless of age or breed
Not ideal for: Dogs with chicken or salmon allergies or those not receptive to supplements
- Protein:Whey Protein Concentrate
- Omega-3:180mg
- Amino Acids:L-arginine, L-histidine, L-isoleucine, Leucine, L-lysine
- Flavor:Chicken
Our verdict“Excellent for dogs needing targeted muscle and energy support through supplementation.”
Evanger’s Heritage Classic Puppy Food – 12 Count, 12.5 oz Each
This meat-based puppy food supports healthy growth with added vitamins and omega fatty acids, making it suitable for young dogs needing extra nutritional support. Unlike adult-focused options like Rachael Ray Nutrish, it emphasizes high-quality, grain-free ingredients, which may be more appealing for sensitive puppies. Its inclusion of sardines and chelated minerals promotes immunity and a healthy coat, but the smaller individual size limits long-term use for larger litters or multiple puppies. It’s best for owners seeking a premium, meat-rich starter diet that emphasizes immunity and wellness from an early age.
Pros:- Supports healthy growth with essential nutrients
- Grain and gluten free for sensitive pups
- Rich in omega fatty acids for skin and coat
- Made with high-quality, locally sourced ingredients
Cons:- Limited flavor options
- Smaller sizes may require frequent restocking
- Not suitable for adult dogs
Best for: Puppies requiring high-quality, meat-rich nutrition for healthy development
Not ideal for: Adult dogs or those with meat allergies or sensitivities to fish-based ingredients
- Count:12
- Size:12.5 oz each
- Type:Puppy Food
- Ingredients:Meat-based, sardines, vitamins, chelated minerals
- Dietary:Grain & gluten free
Our verdict“Ideal for puppy owners wanting a high-quality, meat-based diet to promote immunity and healthy development.”
Purina ONE Plus Healthy Weight High-Protein Dog Food – 16.5 lb
This option stands out for its high-protein content centered on real turkey, making it an excellent choice for dogs needing to build or maintain muscle while gaining weight. Compared with the Blue Buffalo formula, it emphasizes protein more heavily, which benefits underweight dogs that need muscle support. Its crunchy and tender kibble combination enhances palatability, encouraging eating in picky or underweight dogs. However, it can be pricier than basic brands, and some dogs may prefer different flavors or textures, which could limit acceptance. Made in the USA, it provides a balanced blend of nutrients for overall health, especially for dogs with higher activity levels or those recovering from illness.
Pros:- Supports weight management and muscle health with high protein content
- Includes antioxidants and glucosamine for immune and joint support
- Palatable mix of crunchy bites and tender morsels
Cons:- May be more expensive than basic dog foods
- Some dogs may prefer different flavors or textures
Best for: Owners of active or recovering underweight dogs needing muscle support and appetite stimulation
Not ideal for: Pet owners seeking budget-friendly options or dogs with sensitive stomachs preferring grain-free diets
- Weight:16.5 lb
- Ingredients:Real turkey, antioxidants, glucosamine, omega-6 fatty acids
- Purpose:Supports weight control, muscle health, immune support, joint health, and dental health
- Form:Dry kibble
Our verdict“This food is well-suited for owners looking to support muscle gain and weight in active or recovering dogs willing to pay a premium for quality ingredients.”
Nutrish Healthy Weight Wet Dog Food Paté, 13 oz. Can, 12 Pack (Rachael Ray)
This wet food makes the list for its natural ingredients, featuring real turkey and visible veggie pieces, offering a flavor and texture profile that can entice dogs who are underweight and need encouragement to eat. Unlike the Blue Buffalo dry formula, it provides hydration and a more appealing texture for dogs with reduced appetite or dental issues. Its added vitamins and minerals support overall health, but the limited flavor options and the use of cans might be less convenient for owners seeking multi-meal versatility or dry options. It’s a good choice for those prioritizing natural ingredients and easy-to-digest nutrition, especially for dogs who prefer wet food or need extra hydration.
Pros:- Made with real turkey and visible veggie pieces for appetizing appeal
- Supports healthy weight management with natural ingredients
- No fillers or poultry by-products, emphasizing quality
Cons:- Limited flavor options may reduce variety
- Cans require storage and handling that some owners may find inconvenient

Not ideal for: People seeking shelf-stable, dry foods or those on a tight feeding schedule due to can handling
- Weight:13 oz. per can
- Pack Size:12 cans
- Main Ingredients:Real turkey, visible veggie pieces
- Suitable For:Adult dogs
- Features:Supports healthy weight, natural ingredients, added vitamins and minerals
Our verdict“This wet food is ideal for owners looking for a natural, flavorful option to support underweight dogs with a preference for moist diets.”
Blue Buffalo Life Protection Formula Healthy Weight Adult Dry Dog Food, Chicken & Brown Rice, Supports Immunity, 5 lbs
Compared to the other two options, this Blue Buffalo formula stands out for its focus on natural ingredients paired with LifeSource Bits, which deliver antioxidants, vitamins, and minerals to boost immune health. It emphasizes lean muscle development through real chicken and brown rice, making it suitable for dogs that need to gain weight without excess fat. The inclusion of glucosamine and omega fatty acids supports joint health and coat condition. Its grain-inclusive formulation may not suit dogs with sensitivities, and the smaller size limits long-term feeding options for large or multiple dogs. Nonetheless, this makes a solid choice for owners wanting a balanced, nutrient-dense dry food that supports overall health and weight management in a more natural way.
Pros:- Supports healthy weight and lean muscle with real chicken and brown rice
- Includes antioxidant-rich LifeSource Bits for immune support
- Formulated with glucosamine and omega fatty acids for joint and coat health
Cons:- Limited size options may restrict long-term use

How We Picked
Our evaluation focused on the nutritional profile, ingredient quality, ease of feeding, and versatility of each product. We prioritized formulas designed for weight gain, with an emphasis on high protein and calorie density. Products were also assessed for their suitability for different dog sizes, ages, and health conditions, along with the overall value they provide. Rankings reflect a balance between effective weight gain support and practicality, ensuring dog owners can choose options that fit their specific circumstances and budget.Factors to Consider When Choosing Dog Food For Underweight Dogs
Choosing the right dog food for an underweight dog requires understanding several key factors. Beyond calorie content, ingredient quality and digestibility play crucial roles in healthy weight gain. It’s also important to consider your dog’s age, activity level, and any health conditions that might influence dietary needs. Making informed decisions can prevent overfeeding or feeding products that don’t support gradual, sustainable weight gain. Here are some critical factors to keep in mind when selecting the best food for your underweight dog.Nutritional Density and Calorie Content
For underweight dogs, the primary goal is to deliver more calories in a manageable portion. High-calorie formulas or supplements can help promote weight gain, but too many calories too quickly may cause digestive upset. Look for foods with a dense caloric profile—often achieved through ingredients like fats and oils—while maintaining quality nutrition. Balancing calorie density with digestibility is key to avoiding gastrointestinal issues and ensuring steady weight gain.
Ingredient Quality and Protein Sources
The quality of ingredients directly affects how well your dog absorbs nutrients and gains weight. Prioritize foods with real meat, whole grains, and minimal fillers or artificial additives. Protein-rich options support muscle development, which is vital for underweight dogs, especially those recovering from illness or injury. Avoid products with low-quality byproducts or excessive fillers that may hinder nutrient absorption or cause allergies.
Formulation for Specific Needs
Some dogs require specialized formulas based on their age, activity level, or health conditions. For instance, highly active or working dogs may need even higher calorie content, while older dogs might benefit from added joint support or softer textures. Understanding your dog’s unique needs helps you select a product that promotes healthy weight gain without overburdening their system.
Ease of Use and Palatability
If your dog is a picky eater or has a sensitive stomach, the flavor and texture of the food matter. Some high-calorie options are liquid or semi-liquid, making them easier to supplement or feed to dogs with dental issues. In contrast, some dogs prefer dry kibble, which can be more convenient for long-term feeding. Always consider how likely your dog is to enjoy and tolerate the food to ensure consistent feeding and weight gain progress.
Cost and Value Considerations
Effective weight gain doesn’t necessarily mean the most expensive product, but investing in high-quality ingredients often leads to better health and faster results. Balance your budget with the nutritional needs of your dog, and remember that supplements and concentrated formulas are typically more economical on a per-calorie basis. Keep in mind that some products may require additional supplementation or mixing with other foods for best results.
Frequently Asked Questions
Can I feed my underweight dog regular adult dog food to help them gain weight?
While some adult dog foods are calorie-dense, they may not be sufficient for rapid or targeted weight gain in underweight dogs. These foods are formulated for maintenance, so they might lack the extra calories and nutrients needed. Special high-calorie formulas or supplements are often necessary to support healthy weight gain without overfeeding or causing digestive issues. Consulting with a veterinarian can help determine the best feeding strategy tailored to your dog’s specific condition.
Are wet foods better than dry foods for underweight dogs?
Wet foods can be more palatable and easier to digest for some dogs, making them a good option for picky or sensitive eaters. They also provide additional moisture, which can aid digestion and hydration. However, dry foods tend to be more calorie-dense per serving and are more convenient for long-term feeding. Combining both types or choosing high-quality wet foods with added calories can offer a balanced approach for underweight dogs.
How quickly should I expect my dog to gain weight on a new diet?
Weight gain rates vary depending on the dog’s initial condition, age, and overall health. Typically, a gradual increase of about 1-2 pounds per week is a healthy target for most dogs, but some may gain faster or slower. Consistency is key—monitor your dog’s weight regularly and adjust portions accordingly. Sudden rapid weight gain should be avoided as it can stress the dog’s body; steady, incremental gains support healthier outcomes.
Are high-calorie supplements safe for long-term use?
When used appropriately, high-calorie supplements can be safe and effective for supporting weight gain, especially in severe cases. It’s important to follow dosing instructions and consult with your veterinarian to avoid over-supplementation. Long-term use should be part of a comprehensive plan that includes a balanced diet and regular health monitoring. Overreliance on supplements alone is not advisable; they should complement a complete, high-quality diet.
Should I switch my dog’s food if they’re not gaining weight?
Not necessarily. First, evaluate portion sizes, feeding frequency, and the overall diet. Sometimes, increasing portions or offering higher-calorie treats can make a difference. If adjustments don’t work, consider switching to a more calorie-dense or nutrient-rich formula, but do so gradually to avoid gastrointestinal upset. Always consult with a veterinarian before making significant dietary changes to ensure the new food aligns with your dog’s health needs.
Conclusion
For dog owners seeking steady, healthy weight gain, Hill’s Science Diet Adult Perfect Weight Dry Dog Food remains the best overall choice due to its balanced nutrition and palatability. Those prioritizing quick calorie boosts might prefer PetAg Dyne High Calorie Liquid Nutritional Supplement or Dog Muscle Gain Power Chews. For owners of active or severely underweight dogs, Best Breed Dr. Gary’s Working Dog Diet offers tailored support. Beginners or pet owners on a budget will find Pedigree Healthy Weight Adult Dry Dog Food or Nutrish Healthy Weight Wet Food practical options. Ultimately, matching the product to your dog’s specific health profile and activity level will yield the best results for their recovery and vitality.
