Rosemary is a popular herb. Some people suggest using it with dogs, while others warn about possible side effects. Learn the truth about rosemary and dogs.

Rosemary is a popular culinary herb and a versatile plant that offers potential benefits for dogs. From fresh rosemary to rosemary oil, understanding the differences between the two forms can help pet owners make informed choices for their canine companions. Moreover, learning how to grow and propagate rosemary ensures a fresh and sustainable source of this herb for both culinary and therapeutic purposes.

Does Rosemary Cause Seizures in Dogs

I love rosemary and have several large plants in my garden. It's an easy plant to grow and propagate. I use it in homemade hair and body oil, and it's a great addition to garlic-herb butter spread for homemade bread.

I don't feed my dogs rosemary, but I diffuse rosemary essential oils and use the oils in household products and flea-repellent sprays. Some anecdotal evidence suggests that certain essential oils, including rosemary oil, may trigger seizures in dogs. However, scientific studies on this topic are limited. The study I found did equate some essential oils to seizures in dogs, but the study didn't include rosemary oil.

Benefits and Risks of Rosemary for Dogs

Rosemary contains antioxidants and anti-inflammatory properties that may benefit dogs when consumed in moderation. However, excessive intake of rosemary can lead to adverse effects such as gastrointestinal upset, allergic reactions, or potential toxicity, especially if ingested in large quantities.

Although there isn't clear science that has connected rosemary (the herb or a quality essential oil) to seizures in dogs, if a dog is prone to seizures, I would avoid rosemary extract and essential oil to be safe unless told otherwise by their veterinarian.

Fresh Rosemary vs. Rosemary Oil

When properly diluted, fresh rosemary can be used in cooking or as a natural flea repellent for dogs. On the other hand, rosemary oil is highly concentrated and should be used with caution due to its potency. When using rosemary oil for dogs, always dilute it properly and avoid direct application to the skin to prevent irritation or sensitization. You should also buy rosemary essential oil from a reputable pet brand. This can ensure the safety and quality of the product.

Pet Products that Contain Rosemary Oil

Growing Rosemary

Growing rosemary is relatively easy. It thrives in well-drained soil, plenty of sunlight, and moderate watering. I grow rosemary in containers and directly in the ground. It grows best in a location with good air circulation and protection from harsh weather conditions. Regular pruning helps maintain the plant's shape and encourages new growth.

Propagating Rosemary

Rosemary can be propagated from stem cuttings, making it a cost-effective way to expand your rosemary garden. I take cuttings from healthy rosemary plants before they begin to flower. I remove the lower leaves of my cuttings, dip the ends in a rooting hormone, and plant them in organic, seed starter soil, which is well-draining. It's important to keep the cuttings damp (but not too damp) until the roots develop, at which time they can be transplanted into a larger container or garden bed.

The rooting hormone is optional. I use it to give my cuttings a better shot.

Making Hair & Body Oils with Rosemary

Please note that this recipe is for humans, not dogs. Rosemary prevents dandruff, improves scalp circulation, promotes hair growth (and reduces hair loss), and relieves scalp irritation. You can add it to shampoo or conditioner or make a hair/body oil.

Ingredients

  • 2 stems of fresh rosemary leaves (they must be dry)
  • 2 cups of any carrier oil of your choice; I use hemp seed oil, almond oil, or olive oil

Directions

  • plus the rosemary leaves from the stems, discard the stems – I use a slotted spoon, dragging the stem through the holes to quickly remove the leaves
  • mix the leaves with the oil of your choice and boil on low heat until the rosemary turns a dark green
  • remove the pot from the heat and allow the mixture to cool
  • use strain the oil, removing the leaves, and transfer into an application container (for the scalp), or container for body oil.

DIY Rosemary Flea Repellent for Dogs

Fresh Rosemary: Using fresh rosemary, remove the leaves and boil the rosemary on low heat for thirty minutes. Allow the rosemary water to cool, then strain the leaves from the water. Transfer the rosemary water to a spray bottle. Store in a cool, dry place.

Rosemary Essential Oil: Add 10-15 drops of rosemary essential oil to a 16-ounce spray bottle, fill the bottle with water, and store it in a cool, dry place.

Avoid your dog's face when applying the flea-repellent.

Final Thoughts on Rosemary for Dogs

While rosemary offers potential benefits for dogs, including antioxidants and anti-inflammatory properties, it's essential to be aware of the risks associated with its consumption and the potential risk for dogs prone to seizures. My dogs aren't prone to seizures, but if this were a concern, I would work with our veterinarian.

I would only add rosemary to my dogs' diet under the direction of a holistic veterinarian. Otherwise, I'll continue using it in hair and body oils, household products, and flea-repellent sprays.
