Lavender presents a moderate risk to pets when ingested. Dogs and cats can experience mild nausea and vomiting when they chew on the leaves or flowers. My practice sees cases when pets ingest garden lavender and become ill. The essential oils of lavender are of greater concern than the fresh lavender plants.

Essential oils concentrate toxins and are therefore very dangerous. Cats lack the liver enzymes necessary to metabolize these compounds. On average, a single lick of the oil causes respiratory distress. Never diffuse oils in pet-occupied rooms. Store bottles safely from curious pets.

There are safe choices for lavender fans. Rosemary provides a similar aroma with no danger. My cats pay no attention to my rosemary plants. Lemon balm has calming benefits safely. All of these non-toxic selections create worry-free aromatic homes for pets.

Keep others out effectively. Successfully plant lavender in raised garden beds or similar areas that are inaccessible to dogs. Use the enclosed diffusers for essential oils. I keep all of my oil bottles locked in cabinets to prevent an incident with a kitten. These barriers keep pets safe while allowing for the safe use of lavender.

Be aware of signs of an emergency such as tremors or breathing difficulty. These are symptoms of essential oil poisoning and would need attention immediately. Before you need it, have the vet's phone number handy. I have activated charcoal in our emergency kit in case of accidental ingestion. Being prepared can help save lives in the event of lavender exposure.
