How much melatonin can you give a 9 lb dog?

For a 9 lb dog, a typical melatonin dosage is around 1 to 3 mg, but it's essential to consult with a veterinarian before administering any supplements. Dosage can vary based on the dog's specific needs and health conditions. Always ensure the melatonin is free from additional ingredients like xylitol, which is toxic to dogs. Monitoring your dog for any adverse reactions after giving melatonin is also advisable.
