Therapeutic aids for dog anxiety and aggression

Happy dog

There are therapeutic aids that may help reduce stress, anxiety and improve aggression in dogs. These aids might be things we can alter in their environment to supplements and medications.  In many cases, things alterned in a dogs environment, such as sound therapy or a pressure vest can be used in conjunction with a supplement or medication. In general it’s best to check with your vet about using any supplements on their own or with medications.

Some of these aids work short term bandaid on a temporary basis, others may work longer term to positively affect mental health overall. Most short terms may reduce stress or acute anxiety. A calmer dog is a less stressed dog, and a less stressed dog is less likely to become aggressive. There is also a direct relationship between chronic stress and aggressive behavior.

Some therapeutic supplements can be particularly beneficial for behavior modification work since the main goal to aim for is a calm and relaxed dog. Others therapeutic aids may work to just generally lower stress over all.

Some may make more lasting changes in the brain such as those effects neurotransmitters like serotonin or GABA. It’s a mistake to assume because something is natural that it will not have a drug like effect. Supplements should be given to your dog only in consultation with your vet.

Vests and blankets

Generally any jacket, vest or weighted blanket is considered safe for your dog because if they don’t like it they will let you know! However if you have any issues putting on or taking clothing, boots, etc. in general off your dog, you should work to desentize them to wearing any of these items first.

As with all things and dogs it’s always best to not change too much of anything at once, and go cautiously about your approach. Try the vets or blanket for short periods of time with the intention of figuring out whether they can tolerate it before moving on to see if there is a positive effect.

Research has suggested that deep pressure vests can have positive effects on dogs from reducing stress to helping dogs recover from stress.

As above, there is some evidence that suggest pressure can help calm dogs and helps them recover from stress faster. A weighted blanket might be ideal for dogs that do not enjoy handling. However, getting dogs into the various pressure vests are not always easy or necessarily safe for some dogs. The blanket may be a much easier although more expensive option.

What it is used for: Stress recovery, thunderstorm phobia, dogs that do not enjoy handling that may benefit from pressure.

Calming music & Sound

White Noise

White noise contains many frequencies with equal intensities and is often used for masking other sounds.

While there is very little research on the use of white noise with dogs, studies with elderly people shows that white noise also helped decrease state anxiety.(8) It has also been sown to help reduce the anxiety of patients admitted to Cardiac care units,(9) as well as reduce anxiety, blood pressure and pain in patients.(10)

It may useful for those dogs who suffer from separation anxiety we well as those dogs who get easily stimulated by sound, whether from kids, guests, noisy neighbours or outdoor sounds.

Remember, each dog is an individual and will respond uniquely.  Always talk to a vet to determine whether your dog could benefit from any supplements or natural remedies.


In an ideal world it would be best to try out single ingredient supplements. This helps you know what specifically works or doesn’t work for your dog. However, many supplements for dogs are a combination of compounds. Keep in mind that this may actually be more beneficial, but also note that the mix might contain the most of the cheapest ingredient.

Also note, that some of these supplements can have powerful effects. Just because they may be considered natural does not mean they might not have drug-like effect.

Not all dogs will respond in the same way.If you considered supplements for your dog, keep good records of amounts given, times of day, food, and behavioral observations. Some supplements may take days to have an effect (this is because some neurotransmitters are are slow to change – and this is a good thing). Others are more fast acting and may have more temporary effects.


Theanine is known for its relaxing and calming effects on the brain and has been studied for its potential therapeutic uses. For dogs, best use is for short term or situational anxiety. Could be very beneficial using L-theanine in conjunction with a course of behavior modification.

Theanine is a naturally occurring amino-acid primarily found in tea leaves and in some mushrooms. L-theanine is suprisingly effective for short term anxiety for many people.

Theanine works by increasing the levels of certain neurotransmitters in the brain, by enhancing GABA, which then increases dopamine and serotonin (1, 2, 3 ). These neurotransmitters work to help regulate mood, sleep, and cognitive function. Theanine has been found to reduce stress and anxiety, improve sleep quality, enhance cognitive performance and focus, and boost immunity.

Hemp Oil and other hemp products

Hemp Oil Extracts

Hemp oil is an oil that is derived from the hemp plant, also known as Cannabis sativa. Hemp oil is rich in essential fatty acids, including omega-3 and omega-6, which are important for maintaining healthy skin, hair, and nails. It is also a good source of plant-based protein and is high in vitamin E, a potent antioxidant.

Hemp oil contains several compounds that have been shown to have anxiolytic (anti-anxiety) effects. Learn more about hemp oil here.

It’s important to note that individual responses to hemp oil and its components can vary, and more research is needed to fully understand the anxiolytic effects of these compounds. It’s always important to speak with a healthcare provider before using any supplements to manage anxiety or other health conditions.

You can find hemp oil products for pets on Amazon here.

Note that Premium Care Hemp Dog Chews, for example, also include valerian root, l-tryptophan (see below), chamomile as well as hemp oil and organic hemp.

As with all combined ingredient products, you may be getting more of the cheaper ingredient in the mix.


The use of L-tryptophan and 5-HTP as dietary supplements should be done under the guidance of a healthcare professional, as they can have serious side effects and interact with other medications.

L-tryptophan is the precursor of serotonin, and import neurotransmitter in the brain implicated in anxious and aggressive dogs. Diets supplemented with L-tryptophan may not change anxiety related behavior in dogs that don’t show clear signs of abnormal behavior.(5) While there are l_tryptophan supplements for dogs, some include other compounds which makes it difficult to tell what is having the effect.

L-Trypotophan gets converted into 5-HTP and 5-HTP crosses into the brain more easily than L-tryptophan. Before using, read up on side effects and warnings of L-tryptophan and 5-HTP use.

In some cases, dogs are unable to calm down enough to make much progress with behavior modification. These are dogs with a different or unbalanced brain chemistry. In some cases dogs are predisposed to a unbalanced brain chemistry, and in other cases chronic stress may have altered physiology enough that only medication will assist in bringing things back to a healthy homeostasis.  Aggressive and anxious dogs might benefit from medication.  

Talk to your vet / vet behaviorist if your dog may be a candidate. In most cases, an in person evaluation and history taking can indicate if your dog is showing signs that there is a need. Learn more about behavioral medication for dogs here.
