The essentials

What is valerian root?

Valerian root comes from — as the name suggests — the valerian plant, which is a flowering perennial that is native to the grasslands of Europe and Asia and later naturalized in North America. The plant is actually quite beautiful and blooms with small white, purple, or pink flowers during the summer months. The herbal supplement, which is used by humans, dogs, cats, and other species, comes from the valerian’s roots.

Its roots have a distinct, rather unpleasant odor that differs from its scented flowers. But once you get over the rancid aroma, owners can manage their dog’s stress and anxiety with the sedative qualities of the root.

How does valerian root work for dogs?

While the exact science behind it is unknown, it is thought that valerian root quells fear and anxiety in canines by increasing gamma-aminobutyric acid (GABA) to their brain. This in turn blocks the neurotransmitters that lead to anxiety. The herb is also believed to help dogs fall asleep faster and become better rested, which in turn helps them to manage stressful situations.

Is valerian root safe for dogs?

Generally speaking, valerian root is safe for dogs. When administered correctly, this herbal supplement can help calm nervous, anxious, stressed, or fearful pooches. Always consult your veterinarian regarding dosage, as too much can lead to lethargy and drowsiness, as well as more extreme symptoms like vomiting.

Because of its sedative effect, valerian root is not recommended for older dogs, puppies, pregnant/lactating dogs, or any dogs with underlying health issues. Unsure if your dog is a good candidate for the herb? Check with your vet first to be absolutely sure.

When should you give a dog valerian root?

As mentioned, the valerian root’s sedative and anti-anxiety properties can help calm your dog down during stressful situations. This can include:

  • Appointments. Most dogs turn the other direction when they see the vet’s office or groomer. Consider giving your dog a valerian root supplement before their scheduled appointments to calm their nerves. In the case of veterinary visits, be sure to consult with your vet before giving your dog valerian root as it may conflict with certain testing.
  • Loud noises. Between thunderstorms, fireworks, and generally loud cities, a holistic remedy can ease any anxiety your dog has from noisy environments or situations.
  • Transportation. Some dogs don’t take too kindly to any sort of transportation, whether it be by car, train, or plane. Using valerian root before a trip can eliminate some of your pup’s fear surrounding it.
  • Separation anxiety. If you’ve ever come home to torn up furniture or puddles of pee, then you know all too well about canine separation anxiety. Valerian root has been shown to help curb a dog’s anxiety when their owner is away.
  • Changes to their environment. Maybe you’re moving, or maybe one of your other pets passed away — or maybe you just plan on having some visitors over. Any shifts to a dog’s environment can induce stress, and valerian root may help them manage it.

Side effects of valerian root for dogs

Valerian root is considered a relatively safe supplement for dogs with minimal side effects. But that’s not to say side effects can’t happen. The root can interact with other medications your canine companion may be on, including SSRIs, anti-epileptic medications, and antifungal drugs. You should also be careful about administering the herbal supplement prior to a medical procedure or surgery. Additionally, dogs that are pregnant, lactating, or puppies should not take the herbal supplement because the root’s sedative properties haven’t been evaluated with these demographics.

Side effects of valerian root include:

  • Drowsiness
  • Low body temperature
  • Unsteadiness on feet
  • Lethargy
  • Sedation

As with any new supplement you’re giving your dog, it’s best to start in small doses and monitor their reaction. If your dog experiences worrisome side effects from valerian root, contact your veterinarian or seek emergency veterinary care.

How to administer valerian root to your dog

Valerian root is an over-the-counter (OTC) supplement found in stores or online. It’s important to use the herb correctly to avoid adverse reactions. Follow this guide for giving your dog valerian root:

What is the correct dosage?

The correct dosage of valerian root depends on your dog’s stress level, weight, and the form of the herb given. Your packaging should include dosage information, and your veterinarian will also be able to help guide you. “I would always recommend starting at the lowest dose possible and evaluate response or any undesirable side effects,” says veterinarian Dr. Bruce Armstrong.

What form does it come in?

Dried or fresh valerian root can come in tinctures, tablets, and capsules. It also may be found in an oil or chew combined with other soothing or calming pet-safe spices like chamomile or ginger root. If your dog isn’t taking the supplement, try turning it into a treat by encasing it inside a small piece of cheese or peanut butter.

We all want our furry friends to be happy and free of stress. While no supplement or medication serves as a magic wand for eliminating canine anxiety, it’s comforting to know there are products available to help offset your pooch’s fears. If you think your dog is often scared, valerian root may be the perfect remedy for them.
