Melatonin For Dogs: Melatonin for dogs is a sedative hormonal supplement used to treat many kinds of anxiety, hyperactivity, restlessness, and other conditions. It is a naturally occurring hormone produced by the pineal gland. Many pet owners prefer to use it for their dogs instead of drugs that may contain chemicals and have harmful side effects. You can purchase melatonin over the counter, though the FDA has not approved it for use in dogs.

You should not give it to your dog without first consulting a veterinarian, as it may react poorly with certain medications, worsen some medical conditions, and pose risks for pregnant dogs or puppies. It has not been thoroughly studied for side effects in canines, though it is generally considered to be safe for dogs, and most owners only report rare and minimal side effects.

Side Effects in Dogs

While melatonin is regarded as safe for most dogs, its still important to talk to your veterinarian before administering it to your pet. Dosage will depend on the size of the dog and his sensitivity to the drug. Its also important to run the supplements ingredient list by your veterinarian.

When Should I Administer Melatonin

Melatonin takes approximately 30 minutes to kick in, so youll want to administer it to your dog roughly half-an hour before a thunderstorm or any other stressful event you are looking to help your dog manage.

For sleep assistance, melatonins should be provided in the evening. As a rule of thumb, its best to provide the melatonin alongside a meal or snack, since ingesting it on an empty stomach may result in intestinal distress.

Treating Hair Cycle Arrest Alopecias

Melatonin has been used to treat a range of different hair cycle arrest alopecias in dogs . These are diseases where the normal orderly progression of hair growth through the different phases anagen, catagen and telogen is halted leading to hair loss.

Melatonin has also been shown to be beneficial in some of the tardive onset breed specific follicular dysplasias . The response of this latter group of conditions to melatonin is probably because they represent a cross-over between true dysplastic diseases where hair is lost due to the formation of abnormal hairs and hair cycle arrest alopecia.

Whilst both hair cycle arrest alopecia and the follicular dysplasia are cosmetic diseases, with no concurrent systemic involvement, they are unacceptable clinical manifestations to many owners, especially in the plushcoated breeds such as the Chow chow and Pomeranian.

Although therapy is the preferred option for many owners, it should take into account the benign nature of the disease so that the side-effects of therapy should never be more detrimental than the disease itself.

Many different therapies have been advocated for management of Alopecia X including neutering entire animals, melatonin, methyl testosterone, growth hormone, trilostane, deslorelin acetate or monitoring without specific therapy.

Work by Paradis has shown melatonin is beneficial in some breeds including Dachshunds, Boston terriers and miniature pinschers with pattern baldness.

The melatonin secreted by the pineal gland enters every cell in the body. It can even cross the blood-brain barrier.

But the pineal gland isnt the only part of the body that produces and secretes melatonin.

Melatonin also comes from the

  • Salivary glands
  • Stomach lining
  • Intestinal lining

In fact, a 2017 French study reported that melatonin in the digestive tract was ten to 100 times higher than in the blood.

This means that melatonin can do much more than help with sleep problems. In this post Ill cover some of the ways melatonin supports your dogs health.

Both of these problems create more risk of chronic disease.

Our bodies have various glands that secrete chemicals called hormones. One such gland is the pineal gland. It is basically a small pea-sized gland located in the brain of both animals and humans. The pineal gland secretes the hormone melatonin, which performs various functions in the body.

The chemical is responsible for regulating our need to sleep. It is responsible for telling us when we should sleep and when we should be awake: or, as most experts put it, it helps regulate the circadian rhythm of your body. In case the melatonin does not develop in a sufficient amount, it can lead to sleep problems. Even in humans, insufficient production of the chemical can lead to conditions such as insomnia.

If youve suffered from insomnia, you know how difficult it can be. Now think about your beloved pet who cannot even speak. Not being able to sleep is a fate some say is even worse than death. To combat the insufficient production of melatonin, vets often prescribe the drug.

Melatonin Dosage For Dogs

What kind of melatonin should you use for your dog, how much should you give them, and how should you administer the supplement?

Once again, you will need to talk to your vet about these questions. As far as choosing a brand, youll want to find one that isnt cut with a number of other active ingredients and always avoid supplements that include xylitol. For the most part, melatonin supplements have a short list of ingredients that are safe for dogs to consume but you should still talk to your vet about the brand youve got before you use it.

Determining the proper dosage will depend on your dogs weight.

A general rule of thumb is that a dog that weighs less than 10 pounds should take 1 milligram. Dogs that weigh 10 to 25 pounds can have 1.5 milligrams. Dogs that are between 26 and 100 pounds can have up to 3 milligrams and dogs over 100 pounds may be able to have up to 6 milligrams.

However, weight alone cannot determine your dogs dosage. Other factors such as preexisting conditions must be taken into consideration. No matter the size of the dosage, you should never give your dog melatonin more than 3 times a day.

It tends to take about 15 to 20 minutes for melatonin to kick in and the effects will last about 8 hours. If you are using it to help your dog sleep through the night, you can give it to her immediately before bedtime and it will do the trick.
