Did you know?
Melatonin was first isolated from bovine pineal glands in 1958 by Aaron Lerner at Yale University. The pineal gland — a small endocrine gland in the brain — produces melatonin in response to darkness as part of the circadian rhythm regulation system. Melatonin supplements are now the most commonly used sleep aid in the United States with sales exceeding 800 million dollars annually. Blind dogs who cannot use light cues to regulate their sleep cycles often benefit particularly from melatonin supplementation.

What You Need to Know
Melatonin is a naturally occurring hormone that regulates sleep-wake cycles. In dogs it is used for anxiety management noise phobia (fireworks thunderstorms) sleep cycle disruption in senior dogs and certain hormonal conditions. The safety profile of melatonin itself is generally good — overdose causes sedation and disorientation rather than serious toxicity. The critical danger is xylitol — many melatonin gummies chewable tablets and liquid formulations use xylitol as a sweetener. This makes checking the ingredient list before any melatonin use essential. Use only melatonin products confirmed xylitol-free.
Breed-Specific Notes
Always check full ingredient list for xylitol before use. Discuss with vet if dog takes other medications.
