Frequently Asked Questions

What is melatonin used for in dogs?

Melatonin is a natural neurotransmitter that helps regulate sleep in humans and dogs. When released, it begins to trigger sleep cycles by promoting calm throughout the body and beginning the process of moving the brain into a sleep cycle. It is naturally occurring in many parts of nature including plants and animals.

In dogs, melatonin plays the same role as in humans and can be found in dogs naturally. Supplements with melatonin are used to raise melatonin levels in dogs to promote a sense of calm throughout their body. This calming method can be used to help dogs relax in stressful situations like fireworks shows or vet visits. In higher doses, it can be used to help dogs get better sleep.

Can you give a dog too much melatonin?

Yes, it is possible to give any living thing too much melatonin. The higher the level of melatonin in the body, the more likely animals are to go to sleep. In moderate doses, enough melatonin can put an animal to sleep. In extremely high doses, melatonin can cause animals to fall into a dangerous sleep by causing the body to stay asleep for too long, or to go too deep into sleep to where it affects brain and body functions.

There is another danger in that introducing high doses of any neurotransmitter can make an animal dependent on it. This happens when their brain stops producing the neurotransmitter naturally since the supply of it readily available is constantly more than it needs. While this is rare with melatonin and other naturally-occurring substances, overdosing for a long time should be avoided.

What are the side effects of melatonin in dogs?

The main effect melatonin is a calming sensation that spreads across the entire body. This calming can relax muscles and reduce stress. However, this calming sensation comes from the early stages of sleep where the body begins to relax. this could lead to your dog falling asleep more easily, and should be avoided in potentially dangerous situations.

There are few if any side effects of melatonin in dogs, and the described effects are the ones that melatonin is generally used for. However, adverse effects can be seen in dogs that are given doses of melatonin that far exceed their dosage limits. This could lead to drowsiness and an increased amount of sleep. If any other effects arise, reduce the amount given to your dog and consult a vet as soon as possible.

How much melatonin should I give my dog?

In most cases, dogs are given medications based on their weight and size. Melatonin supplements are formulated so that one table is given to a small dog. However, some pills should be given in one-half increments for the smaller breeds. Larger dogs may be able to take multiple tablets at a time.

To know how much of a supplement to give your dog, see the dosing requirements on the package. Every package has dosing instructions much like human medications. If the package is unclear or you are unsure, consult a vet before giving the supplement to your dog.
