A popular essential oil used in aromatherapy, tea tree oil is toxic to dogs when ingested. Here's why you must use plenty of caution when using essential oils for pets.
While some essential oils can benefit dogs, others are extremely dangerous especially when used in their concentrated form. Tea tree oil demands extra caution around dogs, cats and small children. Although exposure to any essential oil is generally most concentrated when it directly contacts skin, tea tree oil diffusers and liquid potpourri present specific health concerns to dogs. These items release essential oils like tea tree continually into the air, risking exposure by inhalation.
