Being a dog is not always easy, and many dogs suffer from some type of fear or anxiety when faced with certain situations. It can be separation anxiety when their family leaves home, panic when there is thunder or general stress when visiting the groomer’s or a crowded space, and if so – it might be time to find a solution. Melatonin is a calming aid commonly used to treat stress and anxiety in dogs, and it can take the edge off an unpleasant situation and help four-legged friends cope. But, what does Melatonin do for dogs? The answer is that it safely reduces stress hormones and helps the dog focus on something other than stress and fear.

We owe it to our dogs to help them feel as comfortable as possible, regardless of what goes on around them, and Melatonin is an excellent way to deal with stress related issues.

Melatonin for Dogs Buyers Guide

Once you have decided that Melatonin is right for your dog, to help with his or her anxiety or stress levels, it is time to look for a reliable product that lives up to your expectations. Many Melatonin products for dogs are similar, but let’s have a quick look at what you can expect to find when browsing the internet for available options.

Choosing to turn to Melatonin is a good idea if you have a dog with separation anxiety, one that gets anxious when riding in the car, a hyperactive dog that can’t seem to calm down and even if you have a dog that is showing signs of aggression that you wish to eliminate. Melatonin is given to dogs in small doses, and will only take the edge off their anxiety, and not actually put them to sleep or make them groggy.

Cortisol Levels

Cortisol is a type of stress hormone, which the body needs two enzymes to produce. A higher Cortisol level means a more stressed and anxious dog, and it is this that Melatonin targets – both in dogs and humans. Melatonin inhibits the enzymes that produce Cortisol, which significantly lessens the existence of this stress hormone in the body and gives your dog a chance to calm down and relax.

Chamomile and Passionflower

When you look at the ingredients of products with Melatonin, they more often than not contain Chamomile, passion flower and other natural ingredients, as a natural calming supplement to further relax your dog. It is a great thing to be able to help your anxious pup without having to turn to chemicals, so if you see any of these listed – it is a good thing.

Tablets vs. Soft Chews

While many of these products are similar in content, they might differ some in the presentation. You will have to make a choice for whether you prefer to give your dog a pill, or if a chew treat might be easier. Chew treats, or soft chews will often have a meaty taste or a taste of something your dog will love so that they won’t even know that they are being given a medical supplement. Not a fan of meat? Try these vegan doggy treats!

What is Melatonin?

Melatonin is hormone with antioxidant effects that are known to reduce stress levels, both in humans and in animals, without the use of potentially harmful chemicals. The body produces Melatonin in the pineal gland of the brain, but an additional small dose can have calming effects on dogs that suffer from stress-related issues. Giving a dog Melatonin is a way to deal with harmful behaviors due to stress; such as excessive scratching, biting and licking, and even aggression. In humans, Melatonin supplements are mostly used as a sleeping aid.

Can dogs have Melatonin?

Can you give a dog Melatonin? Yes, Melatonin is safe to use for a dog, as long as you choose a product made specifically for dogs and follow the dosage recommendations. It is a natural way to help them cope with difficult and stressful situations, which can improve their overall quality of life and also make situations less stressful for you as an owner. Do not use Melatonin meant for human use, as the dosage might be different. Always pick a Melatonin product made for dogs.

What will Melatonin do to a dog?

What happens is that the Melatonin inhibits the two enzymes that produce Cortisol – a stress hormone – which lowers the existing Cortisol levels in the body and replaces it with a sense of calm. It is a scientific process proven to work for both dogs, cats, and humans, and it is recommended by many veterinarians. What Melatonin won’t do is leave your dog feeling or acting drowsy, and he or she will be perfectly able to function normally while using it. Some people even use it to help their overactive dogs focus during training sessions – often with surprisingly good results.

Melatonin for dog anxiety (how does it help)?

Anxiety and stress are related, and it is often something stressful that will trigger anxiety in a dog. By treating and lowering the levels of stress hormones in the body, it enables the dog to deal with anxiety in a better- and more efficient way. When reading about Melatonin separation anxiety almost always comes up, since it is a very common issue for dogs and dog owners, and something that can be helped by giving the dog quality Melatonin supplements.

Side effects of Melatonin in dogs?

Side effects caused by Melatonin use in dogs are considered very rare, but it is good to know what they are in case you notice any of the signs. Some dogs might be sensitive, and while it is not common, you might want to consult a veterinarian if you notice symptoms such as stomach cramps, increased heart rate, confusion or itching. Melatonin could also cause changes in a dog’s fertility, but this is also uncommon.

Can I buy Melatonin for dogs over the counter?

Where can I buy Melatonin for dogs, you might ask yourself, and the answer to that is simple. It is not a prescription medication, and you can order Melatonin supplements off the internet or purchase them in your local pet store. The internet will usually give you access to a wider selection, as well as customer reviews and more general info. The more you know before making your purchase and the better prepared you are – the more likely is it that the Melatonin gives you the results you are hoping for.

Dosage – How much Melatonin can you give a dog?

While every product generally comes with indications regarding how much Melatonin you can give your dog, based on how much the dog weighs, it is always best to consult your veterinarian before initiating treatment. There might be some pre-existing condition that (while unlikely) could make Melatonin a bad idea. Another reason for why consulting a veterinarian first is because Melatonin might interfere with other medications your dog is taking, which could cause problems further down the line. Almost all dogs can take Melatonin supplements without risks of complications, but it is better to be on the safe side and talk to your veterinarian first. When it comes to a potential Melatonin overdose dogs aren’t usually at risk, since the amounts in each soft chew or tablet are fairly low. Just make sure you keep the package or the bottle out of reach so that your dog can’t get to it on his- or her own.


If you have tried everything you can think of to calm your dog down during rainstorms, noisy family get-togethers, fireworks and trips in the car, then it is time to take the next step and try a natural calming aid for your furry friend. Stress can wear on both owner and dog and cause difficult situations with destructive stress-related behaviors as a result. Melatonin is a life saver for many doggy households out there, so take a look at what it could potentially mean for your dog and have a quick talk with your veterinarian before making a final decision.

Expert Tip

Never act as if you are feeling sorry for your dog while he or she is dealing with anxiety or a stressful situation, but instead try and act as normal as possible so that your dog can see that everything is okay. Dog’s are good at picking up vibes from their human friends, and they don’t need your stress on top of their own.
