Melatonin is a hormone that promotes sleepiness in humans and dogs. While there is limited scientific evidence, anecdotal evidence suggests that melatonin may help dogs in certain situations such as cognitive dysfunction and autoimmune disorders.
Before giving melatonin or any medication to your dog, always consult with a veterinarian. It is relatively safe to give melatonin to dogs, but be cautious of potential interactions with other drugs and ensure the product does not contain toxic ingredients like xylitol. The ideal dosage range is uncertain, so consult with your vet for guidance. Watch for potential side effects such as drowsiness, dizziness, headaches, and nausea. It is recommended to avoid giving melatonin to puppies until there is more research on its effects.
