The active ingredients — melatonin, L-theanine, ashwagandha, and L-tryptophan — are well-studied in canine applications. The most common adverse reactions (loose stool, mild nausea) typically resolve within 2–3 days or by giving the chew with a meal. If your dog has a pre-existing condition or is on medication, always consult your veterinarian before starting any supplement.
