Did you know?
Peppermint oil contains 40-55% menthol by weight — the compound responsible for the cooling sensation. Menthol activates the same cold receptors (TRPM8) that detect actual cold temperatures creating the perception of cooling without temperature change. This same receptor activation that humans find refreshing is part of why peppermint is so overwhelming to dogs whose sense of smell is 10,000-100,000 times more sensitive than humans. A concentration that smells mildly minty to a human is overwhelmingly intense to a dog.

What You Need to Know
Peppermint oil is concentrated plant extract — approximately 75-300 times more potent than the plant itself. Dogs absorb essential oils efficiently through their skin and respiratory tract making diffusers and topical applications as dangerous as ingestion. The liver processes these compounds and can be overwhelmed. Never use peppermint oil in diffusers in homes with dogs apply it to their skin or fur or give it orally. Fresh peppermint leaves in tiny amounts are significantly safer than the oil.
