Can I give my dog Melatonin; Embracing the dark side

Can I give my dog melatoninIf you own an anxious dog, you may already know about melatonin and its benefits. Although still very much in an experimental stage, the growing interest in its health and behavioral benefits is gaining momentum.

So, what is it, how does it work, and most importantly, is it safe. Can I give my dog melatonin?

What is melatonin?

Melatonin is a naturally occurring hormone produced in all animals, including us. It’s produced by a tiny pinecone-shaped organ called the pineal gland hidden deep in the brain.

Sometimes called the hormone of darkness as it’s only produced at night. Melatonin plays a vital role in regulating our internal clocks or day/night cycles. As the sun goes down, melatonin production prompts nocturnal animals into activity while promoting sleep in diurnal (active during the day) animals.

Melatonin levels fluctuate through the year too, and these levels trigger seasonal actions. Basically, it’s what tells the bears to hibernate. It’s also why we have trouble getting out of bed in the dark winter months. Not only that, but melatonin in dogs also plays a role in reproduction, coat growth, and behavior.

How does it work?

Although it’s a relatively new area of research for dogs, the link between melatonin and sleep in humans has been well known for a long time. Supplements of melatonin were first used to help people with chronic insomnia and alleviate jetlag effects.

As a side effect of treatment, it was noticed that melatonin helps produce a calming effect. Because of this, several studies have been testing its usefulness, with one study suggesting its use as an anti-anxiety measure for captive animals.

Interest has grown rapidly in melatonin and its potential to help anxious dogs, and some dog-specific supplements are now available.

Uses of Melatonin for dogs

Melatonin has the potential to help dogs with a lot of canine-related issues. But the most common uses are to help ease anxiety and to treat seasonal flank alopecia.

However,  it may be prescribed for any number of problems, including;

Research into giving melatonin to dogs is still in its infancy, and while melatonin is relatively risk-free, you should always consult your veterinarian before giving it to your dog.

Although melatonin for humans is readily available as a supplement, dog-specific options are only obtainable without prescription in the USA and Canada. Despite this, melatonin can help your dog feel calmer, healthier, and happier when prescribed correctly.

Melatonin for dogs

Dogs with anxiety

Because melatonin has sedative properties, it’s used to treat dogs with anxiety. Dogs become anxious for any number of reasons. But separation anxiety and dislike of loud noises are two of the most common.

Even dogs that are stressed in new situations can benefit from the calming effects of melatonin. In fact, melatonin is often prescribed instead of tranquilizers as a safer and more natural anti-anxiety medication.

Melatonin for hair loss in dogs

Seasonal hair loss is common in dogs and is connected to lower melatonin levels. During the spring and autumn, dog’s fur falls out at a much faster rate than at other times of the year. But for some dogs, the fur loss becomes so extreme that they develop seasonal alopecia and are left with bald patches on their flanks.

Melatonin promotes hair growth and treats both alopecia and hair loss due to Cushing’s disease.

Helping dogs sleep

Melatonin levels fall as our dogs age, so it’s not unusual for older dogs to get out of step with their regular sleep cycles. Not only that, but as our dogs are living longer, they are experiencing more cognitive challenges like Alzheimer’s and doggie dementia.

One of the effects of this is Sundowner Syndrome, which disturbs the natural awake/sleep cycles. Melatonin can help promote sleep and ease insomnia associated with a health issue like these.

How much melatonin should I give my dog?

Dosage for any drug is essential to get right. Although melatonin occurs naturally in the body, too much can still lead to an overdose. As melatonin is absorbed quickly but excreted slowly, the hormone stays in the body for some time before passing through urine.

Typical symptoms of an overdose include;

  • Vomiting
  • Dizziness
  • Seizures

So always consult with your veterinarian for the correct dosage, who will take your dog’s size and health history into account. As guide melatonin dosage is small, around 1 milligram per ten pounds of weight

  • Dogs under 10 pounds – 1 mg
  • 10-25 pounds – 1.5 mg
  • 25-100 pounds – 3mg
  • Over 100 pounds – 3.6 mg

Depending on the reason you give your dog melatonin determines whether they take it continuously or just as needed.

Side effects of Melatonin

One of the good things about melatonin is that side effects are rare. Nevertheless, melatonin has been known to cause;

  • Upset stomach
  • Stomach cramp
  • Increased heart rate
  • Changes infertility
  • Disorientation and pacing
  • Itching
  • Excessive drowsiness

If you notice your dog showing any of these side effects, stop giving melatonin immediately and consult your vet.

Are there dogs that can’t take melatonin?

Despite the limited side effects and relative safety of melatonin, there are reasons why you shouldn’t give it to your dog. So talking it through with your veterinarian first is vital to protect your dog’s health. The use of melatonin should be avoided if your dog has any of the following medical conditions;

  • Kidney problems
  • Seizures
  • Allergies
  • Diabetes
  • Liver issues
  • Bleeding disorders
  • Is pregnant
  • A puppy under twelve weeks old
  • Already taking other medications

Can I give my dog Melatonin?

For owners that have fearful dogs, melatonin may seem like a miracle cure. Watching a pet struggle with noise phobia or anxiety is distressing and frustrating. But while melatonin is regarded as safe for dogs, it’s still important to consult your veterinarian before you giving your dog medications or supplements.

Although supplements are available in the USA and Canada specifically for dogs, they are not currently sold in the UK. Despite this, most melatonin supplements have the same active ingredients and because of this, it’s tempting to go out and buy the most popular brand. Not all supplements are suitable, though. Some have added ingredients like Xylitol that is potentially deadly to dogs, so talk to your veterinarian first, who can prescribe melatonin.
