Humans aren’t the only ones that feel anxious—our dogs do too. In fact, it’s pretty common for them to feel that way. One 2020 study found that 72.5 percent of dogs display anxiety symptoms. So, many pet parents turn to anxiety supplements for dogs to provide some relief.

“Anxiety is an under-diagnosed condition of our pets and a large number of dogs suffer with nervous disorders,” explains Dr. Linda Simon, a veterinary surgeon. This is because while some owners might recognize the signs, many won’t—or they’ll mistake the symptoms for something else.

“Part of the confusion lies in the fact that signs can vary from mild to severe and dogs show anxiety in different ways,” Simon continues. For example, behaviors that are considered ‘bad,’ such as furniture chewing and yard digging, are commonly a sign of anxiety — but we humans don’t necessarily know that. There are also different types of anxiety in our furry friends. 

Types of Anxiety in Dogs: Understanding Different Scenarios

Anxiety isn’t a one-size-fits-all mental health condition for humans and the same is true for dogs. The different types of dog anxiety include:

General Anxiety Disorder

This is when pups are nervous most of the time. “Dogs who have general anxiety tend to be scared of anything and everything,” explains Dr. Sara Ochoa, a veterinarian from Texas. “These dogs will usually run and hide when someone new comes over to their house [but] they may also lash out at new people if they feel threatened.” 

Situational Anxiety

Unlike general anxiety disorder, a dog with situational anxiety is not anxious all the time—only in certain situations or by a cause that’s easily explained. In other words, it’s triggered by a certain event. Think: fireworks, hearing certain noises, moving, other dogs, thunderstorms, knocks on the door, yelling, etc. 

“When the dog is removed from the situation, their stress levels plummet and they are a ‘normal,’ content dog once again,” Simon explains. Even if the stress doesn’t go away immediately, you’ll see improvement within a few days. Situational anxiety is often caused by a noise phobia. 

Separation Anxiety

“Dogs with separation anxiety fear being left alone and spend every moment of their time pining for their owner to come back,” explains Simon. “While separated from the human they love, their stress levels are sky high and they are unable to relax.”

Of course, all dogs dislike their humans leaving, but a dog without separation anxiety will eventually be able to do other things like sleep, eat, or play while they’re alone. This is not true for a dog with separation anxiety. 

“Most dogs who suffer from separation anxiety are destructive,” explains Ochoa. “They will paw at the doors or carpet.” 

Separation anxiety can occur in any dog, but humans can make it less likely if they teach their puppy how to be alone safely from a young age. “Some breeds are naturally more prone to developing this condition though, so there is likely a genetic component,” explains Simon. 

Dog Anxiety Symptoms to Watch For

Part of the reason why so many humans miss our dog’s anxiety is because the symptoms aren’t similar to the way anxiety shows up in people. Anxiety symptoms can also vary from dog to dog, and they can vary depending on what type of anxiety your dog has. 

Anxiety symptoms in dogs can also be mistaken for different things too, such as hyperactivity, boredom, puppyhood, or a medical condition. For example, a dog may chew the legs of your chair because they’re stressed, or simply because they’re bored and under-exercised. Similarly, they might tremble or be restless because of nerves, or because they’re in pain, old age, or arthritis

That said, here are some anxiety symptoms to look for in dogs:

  • Trembling
  • A reduced appetite
  • Whining
  • Barking
  • Subdued behavior
  • Depression
  • Panting or drooling 
  • Urinating indoors
  • Snapping
  • Restlessness
  • Destructive behavior, such as chewing, clawing at the walls and carpet, digging in the yard
  • Growling
  • Compulsive behaviors, like constant licking
  • Nausea and vomiting

“We often find the behaviors escalate with time if the anxiety goes untreated,” says Simon. “If the dog is punished for their behavior, this will soon worsen things too.”

That’s why, if you notice symptoms that might be anxiety, it’s best to chat with your vet. They will be able to help you diagnose anxiety (or whatever else is causing your pup these symptoms), and come up with a treatment plan. 

Simon says that helping your dog could involve special gear or toys, behavior modification, desensitization, training, avoiding known triggers, medication, and—especially in the first few months—calming supplements. 

How Can Anxiety Supplements for Dogs Help?

Anxiety supplements for dogs come in various forms and each one will work a little differently. However, they all contain at least one ingredient that is known to promote relaxation. 

For example, some of them will help your pup sleep, like melatonin, others will lessen symptoms because they’ll reduce your dog’s stress levels over time. 

Some, though, might just take the edge off by lessening a dog’s sensitivity to certain things, like noise or stressful situations. 

Key Ingredients in Anxiety Supplements for Dogs

CBD oil

There are a variety of ingredients you can look for in anxiety supplements for your dog that are safe and have been shown to be relatively effective, including:

CBD Oil/Hemp Oil

CBD or cannabidiol is known to calm humans, and early research suggests that it is well-tolerated and effective in dogs. If dosed appropriately, hemp-derived CBD oil will not make your pet “high” and only contains a very small amount of THC (less than 0.3 percent). For anxiety, start with a lower dosage, and if your pet is on any medications, make sure to ask your veterinarian if it’s ok to use CBD since CBD and certain medications can have interactions. 


Melatonin is a natural hormone that helps your dog (and humans) relax and sleep, but you can also find it in treats or oils. When given to your dog, it has a sedative effect which could be helpful for separation and situational anxiety. It’s generally considered safe for dogs, but there haven’t been many studies into it or its side effects in dogs, so be sure to chat with your vet if you’re concerned. 


Chamomile is the same flower humans make tea with, and just like in humans, it’s thought to have some sedative, relaxing, and anti-inflammatory properties because it has the active ingredient apigenin in it. It’s often an added ingredient in anxiety supplements for dogs. If your dog tends to get GI upset when they are anxious, chamomile can be a great, safe option for them since it’s a wonderful antispasmodic (calms muscle spasms) and helps reduce gas and pain. There haven’t been many studies of chamomile in animals, though, so the evidence that it works is mostly anecdotal. 


L-theanine is an amino acid that is believed to increase the amount of the neurotransmitter dopamine in the brain. Dopamine plays a role in making humans feel pleasure and satisfaction, so when the level increases, it can ease nervousness. And in dogs, a 2015 study suggests it works the same way—at least when it comes to storm-related anxiety. 


L-tryptophan is another amino acid and scientists think that it increases serotonin levels in the brain, a hormone that plays a role in mood regulation. A small study involving 33 dogs found that it seemed to ease two anxiety-related symptoms: hyperactivity and aggression. 

Valerian Root

Valerian root is a root that appears to be a powerful anti-anxiety ingredient for dogs. For example, one 2018 study found that just smelling it led to less barking and anxious activity in dogs in a kennel. However, the herb can also interact with certain pet medications, so be sure to check with your vet if your pup is taking something regularly to make sure it’s safe for them.


Thiamine is also known as Vitamin B1 and it’s often used by humans to reduce anxiety. It’s an important vitamin for your dog’s overall health because it plays an important role in the functioning of their nervous system, but there are also anecdotal accounts that it can ease stress.

How to Give Your Dog Anxiety Supplements

When giving your dog any new supplement, it’s a good idea to run the ingredients by your veterinarian to make sure they’d recommend it for your dog given their individual medical history. Some ingredients in anxiety supplements for dogs might not interact well with your dog’s medications or be appropriate for your dog’s weight or age.

Your veterinarian can also confirm the correct dosage. All supplements will have clear instructions on dosage, which is usually based on weight, but your veterinarian can let you know if it’s safe to give your dog less or if you should ease into regular usage. 

Also, many of these anti-anxiety supplements can be used together for better results, but make sure to discuss what’s best for your dog with your veterinarian.
