Some dogs find it easy to switch off, while others struggle to settle when life becomes busy or unfamiliar. Understanding what is behind that behaviour is an important part of supporting their wellbeing.
Valerian Root is a botanical ingredient often included in calming supplements for dogs. But what exactly is it, where does it come from, and what do we know about its potential benefits?
What is Valerian Root?
Valerian Root comes from the plant Valeriana Officinalis, a perennial flowering herb native to much of Europe, including Great Britain, and pasts of Western Asia. “Perennial” means the plant lives for several years, growing again each season.
Although Valerian is a flowering plant, it is the underground parts - principally its roots and rhizome, an underground stem - that are used in herbal preparations. These can be dried and ground into powder or processed to produce extracts. Valerian also has a distinctive, strong earthy smell.
Where does its use come from?
Valerian has a long history in traditional human herbal medicine, with recorded use dating back to Ancient Greece and Rome. It became particularly associated with relaxation and sleep.
That history helps explain why it appears in modern calming products. However, traditional use in people does not establish how effective a supplement will be for dogs. Dogs need to be considered separately, including their health, the preparation used and the available veterinary evidence.
How may it support dogs?
Valerian is included in canine supplements intended to support relaxation and settling. Owners may explore this type of support when their dog finds certain situations difficult, such as unfamiliar surroundings, changes in routine or noise events.
The evidence needs careful interpretation. A 2024 controlled study involving 44 dogs found improvements in firework fear with a supplement containing Valerian root, alongside environmental and behavioural advice.
For owners, the practical message is that Valerian may be an option to discuss as part of a wider support plan.
What should owners know before using it?
Before introducing Valerian, ask your vet t check its suitability if your dog takes medication, receives other calming supplements or has an existing health condition. Valerian’s potential sedative effects make combinations with medicines that cause drowsiness a particular consideration.
Do not assume it is suitable for puppies, pregnant or nursing dogs.
Monitor your dog after introducing any supplement. If they become unusually sleepy, unsteady, unsettled or develop digestive symptoms, stop giving it and contact your vet. Avoid increasing the amount simply because you have not noticed a benefit. Supplements take time getting into the system so you have to give between 4-6 weeks to see a change.
