If your dog is on the skinny side, they might benefit from the best weight gain supplement for dogs. Most dogs maintain a healthy weight by eating their food consistently, but there are plenty of dogs that have trouble gaining weight. Senior dogs and rescue dogs from neglectful pasts often need weight gain supplements the most.
Changing your dog to high-calorie food might not make sense. If dogs are picky or sensitive, switching them to a new diet may cause problems. So, many pet parents turn to weight gain supplements to help their dogs bulk up without drastically changing their routine.
Should You Consider the Best Weight Gain Supplements for Dogs?
With so many overweight dogs in the world, most dog parents don’t need to think about weight gain supplements. Yet, there are plenty of instances where a little weight gain could go a long way for a dog’s health. If your vet informs you that your dog is underweight, you should take action.
Weight loss happens gradually over time, but an easy way to spot an underweight dog is to look at their body shape. If their bones are easily visible, such as their hip bones and rib bones, they need to gain some weight. If they have an hourglass figure instead of a small indent at the waist, that’s another sign that they’re underweight.
Weight Gain for Senior Dogs
Many older dogs naturally lose weight as they age because they may lose muscle mass, have worse digestion, and have less appetite. Building up their muscles or switching their food isn’t as easy as it was when they were younger, so weight-gaining supplements are the easier choice for many families with senior dogs.
Weight Gain for Rescue Dogs
When you adopt a dog, there’s a chance they’ll be underweight. Many rescue dogs were abused, neglected, or strays before someone saved them, so they may still be malnourished. Using a weight gain supplement is an easy way to help a rescue dog gain healthy weight so they can thrive in their new life.

Buyer’s Guide for Weight Gain Supplements for Dogs
All the weight gain supplements on this list are effective, but not all dogs require the same supplements. So, here are some features to consider before making a purchase.
Calorie Content
A product needs to be high in calories to help your dog gain weight. Most people think of high-calorie products as unhealthy, but they’re a great way to help your pup gain weight fast. However, the best products will get those calories from ingredients that are beneficial for your dog’s health.
Ingredients
There are a lot of ways to add calories to a product, but not all of them will be healthy long-term for your dog. Before buying a supplement, look at the ingredient list to see if there are ingredients that can give your dog a health boost, such as items benefitting your dog’s skin, coat, heart, joints, digestion, and energy levels. If your dog has any allergies, make sure the product is free of those ingredients.
Supplement Form
The most common supplement form is gel or liquid. Some of those items have tasty flavors to appeal to dogs while others are flavorless to blend in with your dog’s food. If you’re stuck between two products, consider what type of supplement your dog is most likely to eat.
Price
Finally, think about the price of the product. Is the amount of supplement and the quality of that product worth the cost? Sometimes, you’ll need to choose products that fit your budget, but other times, you might be willing to spend more to get a better-quality product.
Frequently Asked Questions
Here are some questions dog parents commonly ask when selecting an appropriate supplement.
Why is My Dog Losing Weight?
Sudden weight loss is often a sign of illness or stress in dogs. Cancer, hyperthyroidism, kidney disease, dental disease, and parasites are all conditions that could cause your dog to lose their appetite. If your dog is rapidly losing weight, visit your vet to rule out any life-threatening reasons.
Why Won’t My Dog Eat Their Food?
If your dog normally eats their food but suddenly stops, pain or illness could be to blame. Talk to your vet about your dog’s lack of appetite, especially if other unusual symptoms are present. If you switched your dog to a new food recently, they might not be interested in the flavor. Tasty food toppers are a good way to increase a dog’s appetite without changing their diet.
How Often Should I Feed My Dog?
Dogs should eat about two meals per day, in the morning and evening. However, puppies need to eat smaller, more frequent meals. When in doubt, ask your vet what they recommend for your dog’s feeding schedule.
Can Exercise Help a Dog Gain Weight?
Many people associate exercise with weight loss, but it’s a great way to help an underweight dog look and feel healthier. Exercise helps dogs put on more muscle and boost their energy levels. Of course, it should be paired with a high-calorie supplement or diet.
Do Weight Gain Supplements for Dogs Have Any Side Effects?
Like any supplements, dog weight gain supplements may lead to vomiting or diarrhea when your dog first takes them. If your dog is usually sensitive when ingesting new foods, you may want to start with a smaller dose than recommended and then gradually work your way up to the ideal dose.
How Long Until You’ll See Results with Dog Weight Gain Supplements?
Weight gain isn’t something that happens overnight. You may need to wait 4 to 6 weeks before seeing any changes in your dog’s health. Yet, every product works at a different pace.
Conclusion
The best dog weight gain supplements are essential if you have a skinny pup. Underweight dogs have weaker immune systems, less muscle strength, and weak joints. So, a supplement is an easy way to help your dog bulk up and get back to a healthy weight. Senior dogs, rescue dogs, and any other skinny dogs may spring back to life after taking one of these beneficial supplements.
