What is Stinging Nettle?
Stinging nettle (Urtica dioica) is a perennial plant belonging to the Urticaceae family. Native to Europe, Asia, northern Africa, and North America, it grows abundantly in nitrogen-rich soils, often near water sources. The plant features serrated leaves with distinctive stinging hairs (trichomes) that release irritating compounds when touched, giving the plant its common name. Once properly harvested and processed through drying or cooking, these stinging properties are neutralised, making it safe for consumption.
Historical Use and Traditional Applications
The therapeutic use of nettle spans centuries, with documented applications in:
- Ancient Greek and Roman medicine (dating back to the 1st century CE)
- Traditional European herbal practices
- Indigenous North American healing traditions
- Ayurvedic medicine
- Traditional Chinese Medicine systems
Historically, nettle was revered for its ability to cleanse the blood, reduce inflammation, support urinary function, improve joint mobility, and enhance overall vitality—applications that modern science has begun to validate in both human and veterinary contexts.

Nettle’s unique combination of minerals, vitamins, and anti-inflammatory compounds makes it an excellent addition to a holistic canine health regimen.
Can dogs have nettle tea?
Yes, dogs can safely consume cooled nettle tea when prepared properly and given in appropriate amounts. The tea should be made by steeping 1 teaspoon of dried nettle in 240ml of hot water for 10-15 minutes, then cooling completely before offering it to your dog. For small dogs, start with just 1-2ml per kg of body weight. Nettle tea can be offered directly in a bowl, mixed with regular drinking water, or added to food. It’s particularly useful for dogs who may refuse other forms of the herb. The tea should be freshly prepared, as it loses potency after 24 hours. Never add sweeteners or other additives that might be harmful to dogs.

Usage Guidelines
Does nettle help dogs with joint pain?
Yes, substantial evidence supports nettle’s effectiveness in managing canine joint inflammation and discomfort. Its natural anti-inflammatory properties help reduce pain, improve mobility, and enhance quality of life for dogs with arthritis or age-related joint issues. Many dog owners report notable improvement in mobility and comfort within 1-2 weeks of consistent administration.
Is fresh or dried nettle better for dogs?
Both forms have therapeutic value, but dried nettle is generally recommended for convenience, safety, and consistent potency. Fresh nettle must be properly harvested (with gloves) and blanched to neutralise the stinging hairs before use, making dried preparations much more practical for most dog owners. Commercially prepared dried nettle also provides more consistent dosing and is available year-round.
How long does it take for nettle to work for dogs?
The onset of action varies depending on the administration method and the condition being addressed:
- Joint pain relief: Often apparent within 1-2 weeks of consistent use
- Urinary support: Benefits typically seen within 3-5 days
- Allergy relief: Generally 1-2 weeks for noticeable improvement
- Skin and coat enhancement: Usually 2-4 weeks of regular administration
Safety and Interactions
Can nettle be combined with other supplements?
Yes, nettle often works synergistically with other herbs and supplements such as turmeric, boswellia, glucosamine, and omega-3 fatty acids. These combinations can enhance effectiveness without increasing side effects when properly formulated. For kidney and urinary support, dandelion leaf and cranberry can complement nettle’s actions. Always consult with a veterinarian about specific combinations.
Does nettle have any side effects for dogs?
Side effects are generally mild and uncommon but may include:
- Temporary increased urination (due to diuretic effect)
- Mild digestive adjustment during initial use
- Potential allergic reactions (rare)
- Possible interaction with certain medications
