L-Theanine for Dogs: What Is It & How Can It Help?

Is your dog shaking after a visit to the vet? Maybe scratching your door every time you leave? While dogs are usually happy-go-lucky, it’s common for them to experience anxiousness and stress in certain situations. L-theanine for dogs addresses this issue, giving your dog some much-needed relief and helping them feel calm and comforted.

This amino acid is a natural solution to your dog’s anxiety-related behaviors. But what is it? How do you give it to your dog? And is it safe? We have all the information you need right here!


What is L-Theanine?

L-theanine is an amino acid found in green tea that humans and pets commonly use to reduce anxiety and stress.

L-theanine was discovered in 1949 as a constituent of green tea. By 1950, researchers isolated L-theanine to study its impact on the human mind and body. In the United States, the Food and Drug Administration (FDA) considers it safe and allows it to be sold as a dietary supplement. The European Food Safety Authority found that L-theanine improves cognitive function, alleviates stress, provides sleep assistance, and even reduces menstrual pain.

When it comes to products for your pooch, L-theanine supplements often also contain natural ingredients like GABA and L-tryptophan that boost the calming impact of L-theanine.

L-theanine works by increasing the levels of dopamine and GABA in the brain. When your dog ingests L-theanine, it’s absorbed into the blood system, crossing the blood-brain barrier. It eventually reaches the brain, providing anti-anxiety effects.

What are the Benefits of L-Theanine for Dogs?

L-theanine is most commonly used to reduce anxiousness, stress, and fear. It’s known for relaxing your dog, leaving them comforted and calm. This not only leaves your dog feeling happy but eliminates destructive behaviors like digging, chewing, and excessive barking.

Here are the most common reasons your dog may experience anxiousness and stress:


Separation Anxiety

A lot of dogs get nervous or upset when left alone for long periods. Dogs are generally friendly creatures that crave social interactions and attention. If you have a sudden business trip or a day-long activity planned, your dog could become scared, confused, or just plain bored and restless. Separation anxiety can lead to urination and defecation in the home, scratching at the door, and other destructive behaviors.

Loss of a Family Member

Speaking of being social, dogs get very close with their family members. They view everyone in the home, including humans, dogs, and cats, as their pack. If an older dog passes away or a child leaves for college, your dog may experience confusion, sadness, anxiousness, or fear. Some dogs will even become depressed, causing them to become lethargic or refuse to eat.


Some dogs are made for adventure, but not all dogs do well on sudden long trips. A dog with social anxiety or other anxiety disorders may experience stress, fear, or nervousness when in the car or taken to a new environment.

Loud Noises

Sensitive dogs may experience environmentally induced stress when they experience something new, even in their own territory. Loud noises like fireworks and storms can make your dog scared and anxious.

Anything Unfamiliar

Other dogs experience worry and fear when a new person enters the home, notice an unfamiliar smell, or even if they don’t like the look of a new piece of furniture. Sometimes you never know what will set your dog off, so it’s always good to monitor their behavior after any change.


L-Theanine For Aggression

Some anxiety disorders don’t make dogs scared or nervous but aggressive instead. This aggression can show itself towards you, other people, or dogs.

Aggression is different from other anxious behavior. Dogs will start by acting defensively, growling and baring their teeth. They might end up snapping at any dog or person that approaches them.

If your dog acts aggressively out of anxiousness, L-theanine can help. By alleviating their nervousness and making them feel calm and relaxed, your dog will be less likely to act out in social situations.


L-Theanine For Sleep

Some dogs have trouble sleeping due to anxiousness at night. Puppies that are not used to your sleep schedule may feel restless and end up wandering around the house.

L-theanine soothes your dog, helping them feel calmer and more relaxed. This can help regulate their sleep schedule. Along with a comfy place to sleep and a safe area to rest, L-theanine can encourage your dog to rest, keeping them more in tune with your family’s sleep schedule and helping them feel calm even when you’re not there.

This also helps older dogs that have painful joints that keep them from sleeping. Similarly, senior dogs can develop the canine version of dementia, causing them to be confused and distressed during the night. L-theanine calms the mind and may help an elderly pup get some shut-eye.


Is L-Theanine Safe for Dogs?

Yes, L-theanine is safe for dogs and has no known side effects. Of course, this doesn’t rule out the possibility of a reaction since all dogs are different. When it comes to humans, some experience a headache or low blood pressure when using L-theanine, while others feel nothing.

How Much L-Theanine Can I Give My Dog?

Like we said, every dog is different. You’ll most likely have to make some adjustments to reach the desired effect for your dog. Study their reactions and behavior after each dosage to see how it impacts their anxiousness.

You can follow some general guidelines if you want to know the L-theanine dosage for your dog based on its size. The safest method is to start with a smaller dose and gradually increase it until you reach the recommended amount for your pup. Check out the guidelines below:

  • 10 – 20 pounds: 100 mg
  • 21 – 40 pounds: 200 mg
  • 41 – 60 pounds: 300 mg
  • 61: 80 pounds: 400 mg
  • 81+ pounds: 500 mg

Dogs can be given L-theanine every six hours. It’s best to give your dog L-theanine around the same time every day, creating a routine for your dog. But if you know a triggering experience will happen (like going to the vet) or an upsetting moment just occurred (like a thunderstorm), give your dog L-theanine so it can take effect around that time.


How Do You Use L-Theanine for Dogs

Looking for an easy and tasty way to give your dog L-theanine? You’re almost there! Healthy Petables has a natural and organic treat that’s both delicious and made specifically to reduce your dog’s anxiousness safely.

Healthy Petables’ dog treats for calming relief only have natural, vegan ingredients that are beneficial for your pup. The active ingredients include CBD oil, L-theanine, hemp seed oil, and chamomile. You’ve heard the L-theanine rundown, but what are these other ingredients?

CBD is a non-psychoactive compound found in hemp. When digested, it supports your dog’s endocannabinoid system (ECS). There are receptors throughout your dog’s body, including in the brain. CBD helps reduce negative feelings like anxiousness, which can leave your dog feeling calm and comforted.

Similarly, chamomile soothes your dog’s nerves, reducing nervousness and fearful behaviors. Hemp seed powder is also used for reducing anxiety but also has high nutritional value. This includes improving blood pressure, lowering cholesterol levels, and having a positive impact on heart health.

Healthy Petables’ CBD and L-theanine treats have a calming effect, making them a great option for dogs that need help feeling relaxed. As an additional bonus, these treats have a tasty green apple and peanut butter flavor dogs can’t resist, making it very easy to give your dog the L-theanine they need.
