Can I Give My Dog Melatonin?

Yes, with care
Melatonin is commonly referenced for dogs at published doses. Published guidance for dogs: under 10 lb: 1 mg; 10-25 lb: 1.5 mg; 26-100 lb: 3 mg; over 100 lb: 3-6 mg, every 8-12h as needed. XYLITOL WARNING: many gummy/fast-melt melatonin products contain xylitol, which is toxic to dogs. Plain tablets only. Check the label every time.
