“I tried some other calming supplements and they didn't help at all. Melatonin helped but the side effects concerned me and it wasn't 100%. Found the mushrooms and [my aging dachshund]  is so much calmer now… I just give him one chew in the evening and it seems to do the trick. The whining and crying was breaking my heart so thank you!”

– Verified Customer

“The Mushroom Relax Pet Chews really really really relax and calm down my 55 pound dog… I love that he is able to get reishi and other calming ingredients in a tasty treat, as I know reishi by itself usually tastes sort of bitter. He definitely enjoys these chews, but never needs more than one!”

– Verified Customer

“She loves the smell of the chews and taste. These chews help her calm down during long rides and storms. She doesn’t go to sleep but lays down without panting. I’m thankful that this company allows me to order the products as I need them and still enjoy the benefits of the subscription. Great product and ingredients. It came recommended from a friend… I’m really happy.”

Real Ingredients

Lion’s Mane Mushroom (Organic)

A mushroom known for its health benefits for both neurologic and digestive health.

Enhances cognitive function, has a calming stress-reducing effect; can benefit senior pets who are experiencing cognitive decline with age.

Reishi Mushroom (Organic)

Reishi mushroom is an adaptogenic fungus, treasured for centuries in traditional wellness practices and often called the “mushroom of immortality.”

Reishi mushroom is calming and grounding due to the effect of its active ingredients on the brain.

Theanine

Theanine is a naturally occurring amino acid most commonly found in green tea leaves.

Theanine has a relaxing and stress reducing effect on dogs and cats.

Tryptophan

Tryptophan is an essential amino acid naturally present in many protein-rich foods.

Tryptophan causes the body to produce serotonin which is a relaxing neurotransmitter, resulting in calmness and reduction in anxiety.

L-Taurine

L-taurine is a sulfur-containing beta amino acid that is naturally produced by dogs, but is considered an essential amino acid for cats who cannot naturally produce it, thus needing  to consume it daily. Taurine has many biological functions, one of which is to stimulate certain nerve cells that provide a calming effect.

Taurine can benefit multiple systems such as cardiovascular, metabolic and neurologic, as well as modulating the stress response through the HPA axis. It can support relaxation and calming through its effect on the nervous system.

Lemon Balm

Lemon balm is a lemon-scented herb from the mint family, traditionally used in European herbal practices for its gentle, calming qualities.

Helps to reduce anxiety and improves overall activity levels and social interactions.

Valerian Root

Valerian root is a perennial herb native to Europe and Asia, traditionally used for its earthy aroma and natural calming properties.

Valerian’s calming properties can provide pets with support for stressful situations like vet or groomer visits, and can help reduce anxiety in general.

Catnip

Catnip is a common herb in the mint family that has calming properties and a special effect on cats.

Catnip is mildly calming to dogs and cats and can help reduce the discomfort of gastrointestinal colic. Cats have a unique response to catnip and love its taste.

Passion Flower

A native North American perennial vine whose flower extract is used for its natural sedative and anti-anxiety properties, calming the nervous system.

Passionflower is a safe herbal calmative for pets.

These really work!

I have a 100 lb dog and an 80 lb dog that are scared of fireworks and thunder. I gave 4 to my 80lb girl and she was out! I gave 5 to my boy and he was chilled out. 🥰

Frequently Asked Questions

All our mushroom extracts are from the leading supplier of organic mushroom extracts: Nammex. They have over 40 years of mushroom growing experience and were one of the first companies to bring organic functional mushroom extracts to North America.

Their ingredients go through rigorous quality control and are tested twice for heavy metals, agricultural chemicals and microbial contamination to ensure they meet all standards for dietary supplements of this nature. All of their extracts are made from certified organic mushrooms (fruiting bodies), organically grown or wildcrafted from deep within mountain regions of China.

Mushrooms used for dietary supplements are seldom grown in North America since they are too expensive. China is the leading supplier of mushrooms worldwide and supplies over 90% of the world’s mushrooms. 

It has a rich history of mushroom use as both food and medicine and is the birthplace of mushroom cultivation, with shiitake being farmed in the early 1200s. China is one of the only places in the world where you can get 100% organic mushroom (fruiting body) extracts that can be sold at an affordable price.

It is extremely important to distinguish the difference between mushrooms and mycelium.

Mushrooms are the "fruit" and reproductive stage of these organisms, while the mycelium is the root system or "body" of the fungus.

Mushrooms contain much higher levels of active compounds like beta-glucans, and there is a large body of research on them. They have also been consumed for thousands of years as food, and many health benefits have been shown from just mushroom consumption.

Mycelium is commonly grown on a grain substrate, and this grain cannot be separated from the mycelium, so much of the final product is actually grain with no mushrooms present. This shows up in high amounts of starch and low amounts of active compounds like beta-glucans. 

For these reasons, Real Mushrooms only utilizes mushrooms in all of its products, with verified levels of important active compounds like beta-glucans, and is always guarded against starchy fillers like grain.

NSF certification ensures the product is manufactured under strict cleanliness, safety, and quality control guidelines. This means you can trust that Daily Dawg Powder meets the highest standards for pet supplements.

Mushroom Relax Chews promote calmness and relaxation for pets during occasional stress or anxiety. They combine mushrooms, adaptogens, amino acids, and herbs that help reduce mild nervousness and improve a pet’s ability to adapt to stressful events.

Dogs: Give 1 soft chew for every 20 pounds of body weight once daily, or as directed by your veterinarian.

Cats: Give 1⁄4 chew twice daily, or as directed by your veterinarian.

Give Relax Chews 30 to 60 minutes before a stressful event for best results.

They can be given daily for ongoing support or as needed for occasional stress.

Yes, Relax Chews are safe for both dogs and cats.

There are no reported negative interactions between mushrooms and common pet supplements or medications. Still, we always suggest checking with your veterinarian before starting any new supplement routine.
