Ashwagandha is a plant in the nightshade family, the same family as tomatoes and peppers. Most supplements are made from the root which is either ground into a powder or processed into an extract.
Ashwagandha is most commonly used for stress support and calming, and there are some instances when it's marketed as an antioxidant or anti-inflammatory. However, results can vary from dog to dog, and the overall evidence base in dogs is still limited.
In healthy adult dogs, ashwagandha is often considered generally well tolerated, but it has not been extensively studied—especially for the long-term.
If your dog has underlying health conditions or takes prescription medications, adding ashwagandha to your dog's routine may be unwise.
Let’s take a closer look.

Ashwagandha Potential Benefits for Dogs
While research in dogs is still emerging, ashwagandha is typically discussed for a few potential areas of support. The key point is that these benefits are not guaranteed, and they may depend on the dog, the product quality, and the specific situation.
Ashwagandha is still a relatively new product for dogs, so the specific benefits are still unclear. That said, some dog parents have reported that it helps with daily calming for anxious dogs. The extent to which it helps, if it does help, is still unclear.
Because ashwagandha is associated with anti-inflammatory and antioxidant activity in broader research, some people use it as a general wellness supplement—especially in older dogs. The hope is that it may support overall resilience by helping the body handle day-to-day stress more effectively.
Some early veterinary research has explored ashwagandha in the context of aging and digestion. This is why you may see it included in formulas marketed for senior dogs or “gut health.” However, these uses still need more large-scale, long-term study.
The Risks of Ashwagandha for Dogs
Even though ashwagandha is often marketed as “natural,” it can still cause side effects and may not be appropriate for every dog. Risks typically fall into two categories: tolerability (side effects) and medical fit (when it should be avoided or used only with close veterinary oversight).
Potential side effects
The most commonly reported issues with herbal supplements like ashwagandha are:
- Digestive upset (vomiting, diarrhea, softer stools)
- Drowsiness or a dog seeming “too sedated,” especially if combined with other calming products
If any of these occur, the safest move is typically to stop the supplement and consult your veterinarian.
Dogs who require extra caution
It may be inappropriate—or require close veterinary supervision—if your dog:
- Is pregnant or nursing
- Has known liver, kidney, heart, thyroid, or chronic GI disease
- Has an autoimmune condition or takes immune-modulating medication
- Takes prescription anxiety medications, sedatives, or other drugs that could interact
Product quality issues
Another real risk is that supplement quality varies widely. Different products may use different plant parts (root vs. leaf), different extraction methods, and different strengths. This makes it difficult to predict how a given product will behave—especially if it is not formulated specifically for dogs.
Bottom line: Ashwagandha may be a reasonable option for some dogs, but it is best approached as a carefully chosen, vet-guided supplement rather than an automatic daily add-on.
Conclusion
Ashwagandha is generally considered safe for dogs at this point, but there's more research needed to truly understand its impact on our pets' lives. It could be beneficial to some dogs, while it could be a bad idea for other dogs.
In any case, mixing and matching multiple supplements together, or adding supplements to a dog's already-medicated routine, are not good ideas without veterinary support.
