Is Your Dog Anxious? What Herbs Can Help — and What to Know First

Anxiety in dogs is one of the most common reasons pet owners reach out to me — and it makes sense. Whether it's thunderstorms, separation, vet visits, or just a generally nervous temperament, watching your dog struggle is hard. Herbal support can genuinely help, but there are a few things I want every pet owner to understand before reaching for something off a shelf.

Dogs Are Not Small Humans (or Small Cats)

This matters more than most people realize. Many herbs that are safe for people are not safe for dogs, and the reverse is also true. Dosing is based on weight — but it's also based on species physiology. How a dog processes a compound is meaningfully different from how a human does. And something appropriate for a 70-lb Labrador may be completely wrong for a 9-lb Chihuahua, or for a senior dog whose liver is no longer working at full capacity.

Cats add another layer entirely — many herbs tolerated by dogs are hepatotoxic to cats. If you have a multi-species household, it's especially important that formulas are designed with the specific animal in mind, not just assumed to be safe across species.

Herbs I Commonly Consider for Canine Anxiety

• Ashwagandha (Withania somnifera) — One of the better-studied options in dogs specifically, with some clinical evidence for stress resilience at appropriate doses. A good choice for generalized anxiety and overall nervous system support.
• Lemon Balm (Melissa officinalis) — Calming and well-tolerated in most dogs. Particularly useful for mild-to-moderate situational anxiety (car rides, vet visits, new environments).
• Chamomile (Matricaria chamomilla) — Gentle and soothing. Works well when anxiety overlaps with digestive upset — stress-belly is a real thing in dogs, and chamomile can support both.
• Valerian (Valeriana officinalis) — Can be effective for more significant anxiety, particularly noise phobias. Dosing matters, and it's not the right fit for every dog — some actually become more stimulated on valerian.
• Passionflower (Passiflora incarnata) — Helpful for dogs that are restless or struggle to settle, especially at night. I tend to reach for this when anxiety has a "keyed-up" quality rather than fearfulness.

What I Always Check Before Formulating

Current medications are the first thing I look at. Many anxious dogs are already on pharmaceutical support — trazodone, gabapentin, fluoxetine, and others — and certain herbs can interact with those in meaningful ways, sometimes amplifying sedation more than intended, or affecting how the medication is metabolized.

I also ask about age, weight, breed, known health conditions, and what the anxiety actually looks like day to day. A dog who panics specifically during thunderstorms gets a different formula than a dog with separation anxiety who paces and vocalizes every time you leave. Context shapes the formula.

My veterinary background isn't just a credential — it's something I actively use every time I formulate for a companion animal. Species safety is always the starting point, not an afterthought.
