There are a wide range of reasons that your dog may not have an appetite—it could be because they’re getting older, feeling sick, or just tired of their usual kibble. However, it’s concerning when your pet doesn’t want to eat, and if it becomes an ongoing issue, an appetite stimulant for dogs can often help your pup resume their normal mealtime habits.

What Are Appetite Stimulants for Dogs?

There are two main types of appetite stimulants for dogs that you’ll find today: prescription and over-the-counter. 

As you might expect, prescription appetite stimulants are generally the most effective option. “Appetite stimulants in dogs work directly in the brain,” says Dr. Katie Pagán, partner doctor at Heart + Paw Fells Point. “They stimulate receptors, specifically the hypothalamus, that help with appetite.” Because these appetite stimulant medications must be prescribed by a veterinarian, they’re often used when underlying medical issues are causing your dog not to eat.

However, there are also over-the-counter dog appetite stimulants that you can try if your pup is just picky about their food. These non-prescription products come in a variety of forms — liquids, nutritional gels, meal toppers, and more — and they often have an enticing smell or taste that encourages your dog to eat. Many also contain vitamins, minerals, and more to ensure your dog is getting appropriate nutrients, even if they’re not eating as much as usual. 

Why Your Dog Might Need an Appetite Stimulant

There are a number of medical issues that can cause a decreased appetite in dogs, ranging from infections to more serious conditions like liver or kidney disease, so it’s important to talk to your dog’s veterinarian if a lack of appetite is an ongoing problem. “We usually prescribe appetite stimulants in dogs post surgery or if they have underlying issues, like cancer, where they may not want to eat,” explains Dr. Pagán. 

However, an occasional lack of appetite may simply be due to an upset stomach, old age, or emotional distress. For example, it’s common for dogs not to eat as usual when they’re boarded, as they’re stressed to be in a new environment without their owners. Some dogs also simply get tired of eating the same food every day and lose their appetite for it.

Other Ways to Stimulate Your Dog’s Appetite

There are a number of other ways to stimulate your dog’s appetite, especially if they’re just bored with their regular kibble. “You can try stimulating your dog’s appetite by offering different types of foods,” recommends Dr. Pagán. “Microwaving wet food can work well or even adding a scoop or two of meat-flavored baby food to your dog’s food. Different smells or strong food smells can entice them to eat on their own.”

If you do microwave your pet’s food, check the food’s temperature before feeding to reduce the risk of burns. And if you add baby food, avoid any foods containing onion or garlic, which can be toxic to dogs.

You may also want to try cutting back on treats and scraps. A dog that is eating a diet high in treats may not eat much dog food for nutrition, because they’re getting plenty of calories from other sources. Additionally, frequent treats and table scraps can turn your dog into a picky eater, making them less likely to eat their own food.

Finally, increasing the amount of exercise your dog gets each day can ensure they’re hungry at meal time.

Appetite Stimulants for Dogs: Tips and Precautions

If your dog hasn’t been eating as usual, you’ll want to take them to the vet to confirm that there’s no larger medical condition at play. “Always consult with your veterinarian first before giving your dog an appetite stimulant,” recommends Dr. Pagán. They’ll be able to provide a prescription appetite stimulant as needed or recommend an over-the-counter option to try, as well as guidance on how to use the product effectively.

When giving your dog an appetite stimulant, it’s important to keep an eye on their well-being to ensure the supplement doesn’t cause any additional problems or gastrointestinal distress. “Appetite stimulants are typically prescribed to sick dogs, so owners must be mindful of that,” she says. “Pet parents should be watching at home for any vomiting, diarrhea, lethargy, or anorexia.”
