This repellent contains natural ingredients that repel insects, including ticks. It is formulated with Witch Hazel as the principal carrier solution. The essential oils are widely accepted as safe for dogs (and can also be used on humans!). Notably it does not contain any Eucalyptus essential oils as some species of eucalyptus are considered to be too potent for dogs and side effects may occur such as skin irritation or make them become more active. It is intentionally left out and replaced by a variety of other essential oils.  

Ingredients:

Witch Hazel, Water, Polysorbate-20 and Glycerin. Essential oils include: Neroli, Lemongrass, Lavender, Cedarwood, Geranium and Neem oil. 

Instructions: Shake well before applying. Hold the bottle about 6 inches away from your dog’s fur. Lightly spray, including ears, legs, tail, and underbody.
