What Is Ashwagandha?

First, let’s get clear on what ashwagandha is. Also known by its scientific name, Withania somnifera, ashwagandha is an evergreen shrub native to India, the Middle East, and parts of Africa. For thousands of years, it’s been a staple in Ayurvedic medicine, where it’s valued as an “adaptogen”—a substance that helps the body “adapt” to stress by balancing hormones (like cortisol) and supporting the nervous system.

In humans, ashwagandha is marketed to reduce anxiety, improve sleep, boost immunity, and even enhance cognitive function. It’s available in powders, capsules, tinctures, and teas, often mixed with other herbs or supplements. But here’s the catch: most of the research on ashwagandha’s benefits comes from human studies. When it comes to dogs? The science is very limited.

Can Dogs Eat Ashwagandha? The Short Answer

No, dogs should not be given ashwagandha casually, and in many cases, it’s best avoided altogether.

While ashwagandha isn’t classified as “toxic” to dogs (unlike chocolate or xylitol), it’s not a harmless supplement, either. There’s no standardized, vet-approved dosage for dogs, and the risks—from stomach upset to dangerous drug interactions—often outweigh the unproven benefits. Think of it this way: just because an herb is “natural” doesn’t mean it’s safe for your pup. Many “natural” substances (like garlic in large doses, or certain essential oils) can harm dogs, and ashwagandha falls into the “proceed with extreme caution” category.

Potential Benefits of Ashwagandha for Dogs (With Big Caveats)

You might be wondering: If it’s not toxic, why not try it? Some holistic veterinarians and pet owners swear by ashwagandha for dogs, claiming it helps with anxiety, joint pain, or immune support. Let’s break down these purported benefits—and why they’re not a guarantee.

1. Stress and Anxiety Relief

Ashwagandha’s claim to fame is its ability to reduce stress, thanks to compounds called withanolides, which may lower cortisol (the “stress hormone”) levels. In humans, studies suggest it can ease symptoms of anxiety and improve resilience to stress. Could this translate to dogs?

Anecdotally, some pet owners report that ashwagandha helps their dogs stay calm during thunderstorms, car rides, or separation. However, there are no large-scale clinical studies in dogs proving this effect. Most of the “evidence” is based on human research or small, unpublished observations.

2. Immune System Support

Adaptogens like ashwagandha are also said to “balance” the immune system, helping the body fight off illness. In lab studies, ashwagandha has shown antioxidant and anti-inflammatory properties, which might support immune function. But again, no studies have confirmed this in dogs, and a healthy dog’s immune system is best supported by a balanced diet, regular exercise, and proper veterinary care—not unproven herbs.

3. Anti-Inflammatory Effects

Chronic inflammation is linked to conditions like arthritis, allergies, and even heart disease in dogs. Some research (in rodents and test tubes) suggests ashwagandha may reduce inflammation by inhibiting pro-inflammatory molecules. While this sounds promising, there’s no data showing it’s safe or effective for dogs with inflammation. In fact, giving ashwagandha to a dog with arthritis could interfere with prescribed anti-inflammatory meds (like NSAIDs), putting them at risk of side effects.

The Bottom Line on Benefits: Any potential upside of ashwagandha for dogs is speculative at best. For every pet owner who swears by it, there’s another who reports no effect—or worse, negative reactions.

Risks and Concerns: Why Ashwagandha Isn’t “One-Size-Fits-All”

The lack of proven benefits is just one reason to think twice about ashwagandha for dogs. The bigger issue? The very real risks it poses, even in small doses.

1. Gastrointestinal Upset

The most common side effect of ashwagandha in dogs is stomach trouble. Symptoms can include:

• Vomiting
• Diarrhea
• Loss of appetite
• Gas or bloating

These issues are more likely if your dog gets a large dose, but even small amounts can upset sensitive tummies. Puppies, senior dogs, and dogs with digestive conditions (like IBS) are especially vulnerable.

2. Drug Interactions

Ashwagandha can interact with medications your dog may already be taking, including:

• Sedatives or anti-anxiety drugs (e.g., trazodone, benzodiazepines): Ashwagandha’s calming effects could amplify drowsiness, leading to extreme lethargy or difficulty breathing.
• Blood pressure medications: Ashwagandha may lower blood pressure, which could be dangerous if combined with drugs that also reduce blood pressure.
• Diabetes medications: Some studies suggest ashwagandha may lower blood sugar, which could cause hypoglycemia (dangerously low blood sugar) in dogs on insulin or other diabetes meds.
• Immunosuppressants: If ashwagandha does boost the immune system, it could counteract drugs given to dogs with autoimmune diseases (like prednisone), worsening symptoms.

3. Hormonal and Organ Risks

Ashwagandha may affect hormone levels, including thyroid function. In humans, it’s sometimes used to support underactive thyroids, but in dogs with hyperthyroidism (overactive thyroid), this could be catastrophic.

There’s also concern about liver and kidney impact. Some herbs contain compounds that stress these organs, and without research in dogs, we can’t rule out long-term damage from regular ashwagandha use.

4. Low-Quality Supplements = Hidden Dangers

Not all ashwagandha products are created equal. Many supplements for humans contain added ingredients like sugar, artificial flavors, or even xylitol (a sugar substitute that’s deadly to dogs). Even “pure” ashwagandha powders or capsules may be contaminated with pesticides, heavy metals, or other herbs that are toxic to dogs.

5. Choking or Blockage Risks

If you give your dog ashwagandha in pill or capsule form, there’s a small but real risk of choking or intestinal blockage, especially in small breeds or dogs who gulp their food.

How Much Ashwagandha Is Safe for Dogs? (If Any)

Here’s the hard truth: There is no universally safe dosage of ashwagandha for dogs. Unlike medications, which are tested rigorously for safety and efficacy, supplements like ashwagandha aren’t regulated by the FDA (or equivalent bodies) for pet use.

Some holistic vets may recommend tiny doses—for example, 100–200 mg of ashwagandha root powder per 10 pounds of body weight, given once daily. But this is a guess, not a science-backed guideline. A 10-pound Chihuahua and a 10-pound Pomeranian with different health histories could react very differently to the same dose.

Our advice: If you’re considering ashwagandha for your dog (e.g., for severe anxiety that hasn’t responded to other treatments), talk to a board-certified veterinary nutritionist or holistic vet first. They can assess your dog’s health, medications, and lifestyle to determine if ashwagandha is even worth trying—and if so, what dose might be safest.

Healthier Alternatives to Ashwagandha for Dogs

Instead of gambling on ashwagandha, try these science-backed, vet-approved strategies to support your dog’s health:

For Stress and Anxiety

• Exercise and Mental Stimulation: A tired dog is a calm dog! Daily walks, playtime, and puzzle toys reduce stress by burning off energy and keeping their mind busy.
• Thundershirt or Anxiety Wrap: These snug garments apply gentle pressure, which many dogs find soothing during storms, travel, or separation.
• Adaptil (Dog Appeasing Pheromone): This synthetic pheromone mimics the scent of a mother dog, helping puppies and adult dogs feel safe and calm.
• Chamomile Tea: A small amount of cooled, unsweetened chamomile tea mixed into food can have mild calming effects with minimal risk (check with your vet first).

For Immune Support

• Omega-3 Fatty Acids: Found in fish oil or algae-based supplements, omega-3s reduce inflammation and support immune function. Always use a vet-recommended dose to avoid bleeding risks.
• Probiotics: A healthy gut = a healthy immune system! Look for dog-specific probiotics (like Purina Fortiflora) to balance their microbiome.
• Fresh, Whole Foods: Blueberries, sweet potatoes, and carrots are packed with antioxidants that boost immunity—plus, most dogs love them as treats!

For Inflammation or Joint Pain

• Turmeric with Black Pepper: Curcumin (the active compound in turmeric) has anti-inflammatory properties. Mix a pinch of turmeric powder with a tiny bit of black pepper (to boost absorption) into your dog’s food. Start small (1/4 teaspoon for small dogs, 1 teaspoon for large dogs) and check with your vet.
• Glucosamine and Chondroitin: These supplements are proven to support joint health in dogs with arthritis. Look for brands labeled “USP verified” for purity.

FAQ: Your Top Ashwagandha Questions Answered

Q: Is ashwagandha toxic to dogs?

A: No, ashwagandha isn’t considered highly toxic, but it can cause serious side effects (like vomiting, diarrhea, or drug interactions) in some dogs.

Q: My dog ate ashwagandha accidentally. What should I do?

A: Stay calm! If it was a small amount (e.g., a sprinkle of powder), monitor your dog for 24 hours for vomiting, diarrhea, or lethargy. If they ate a large dose, or if they have pre-existing health conditions, call your vet or an animal poison control hotline (ASPCA Poison Control: 888-426-4435) immediately.

Q: Can puppies or senior dogs have ashwagandha?

A: Puppies have developing organs, and senior dogs often have health issues or take medications—both groups are at higher risk of side effects. It’s best to avoid ashwagandha for puppies under 1 year or dogs over 10 years old.

Q: My holistic vet recommended ashwagandha for my dog’s anxiety. Should I trust them?

A: Holistic vets have specialized training, but it’s still wise to ask questions: What dose do they recommend? How will we monitor for side effects? Are there alternatives we can try first? If they can’t provide clear answers, consider getting a second opinion from a traditional vet.

Conclusion: When in Doubt, Ask Your Vet

At the end of the day, ashwagandha is a supplement with unproven benefits and very real risks for dogs. While it might work for some pups (anecdotally), the lack of research means you’re essentially guessing with your dog’s health.

Instead of chasing trendy herbs, focus on the basics: a high-quality diet, regular exercise, mental stimulation, and preventive vet care. These are the cornerstones of your dog’s well-being, and they’re far more reliable than any untested supplement.

If your dog struggles with anxiety, joint pain, or another issue, talk to your vet about safe, evidence-based solutions. They can recommend treatments tailored to your dog’s unique needs—no guesswork required.

Your dog depends on you to keep them safe, and that means saying “no” to fads and “yes” to what’s proven. Here’s to many happy, healthy years with your pup!
