While lavender plants are considered safe for dogs, it's best to avoid them eating large amounts.
Lavender contains linalool and linalyl acetate, which are toxic in high doses, but the levels in the plant are low.
However, if your dog has consumed a significant amount of lavender, or if they have any health issues, consult your veterinarian.
Always err on the side of caution when it comes to your dog's diet and seek professional advice if needed.
