Information synthesized from: ASPCA, Rover.com, DogTime, Maven Pet
Quick Answer
✅ YES - Fresh and Dried Basil Safe in Small Amounts
Dogs can safely eat both fresh and dried basil in moderation as a nutritious herb supplement. According to the ASPCA, basil (Ocimum basilicum) is non-toxic to dogs and cats. Basil provides antioxidants, vitamins A and K, and anti-inflammatory compounds that support overall health. However, limit to small amounts—a few fresh leaves or one teaspoon of dried basil daily maximum—and never give basil essential oils.
According to DogTime, basil contains vitamins A and K which support blood clotting, and is full of magnesium for muscle function and energy levels.
