“My American Bulldog gets allergies every year starting in August. Our breeder referred the MYCO Canine Allergies & immunity & the results were nothing short of amazing. The attached pictures are after using the product for a weekend. Nothing else has worked over the years & we have used many products.”

“My dog had such an amazing reaction to this product. It was a game changer for many symptoms we were unsure of and so were vets. She has gone back to how she was behaving and feeling before all her symptoms began!”

“Our German Shepherd has so many allergies, food and environmental. We have spent hundreds of dollars at the vet and on medications with only some improvement.

Great for Digestion—Even My Fussy Senior Great Dane Loves It!

This product has made a huge difference for my Great Dane, Alli, who is over 12 years old. Before using it, she struggled with constipation, sometimes having only one or two bowel movements a week, and was constantly grazing on grass. After finishing our first jar, she has stopped grazing and now has at least one bowel movement every day.

I especially notice the difference when my kids look after her and she misses a few doses. She can become constipated again, but once I start giving it to her regularly, she becomes regular again.

Giving Alli supplements has always been a struggle. She has spit out capsules and even refused entire meals when other products were added to her food. This product is completely different. I simply sprinkle it over her food, and she loves it!

Improved stool firmness

My dog's stool always had a tendency to be soft, no matter what kibble we fed. Even feeding raw, he doesn't have firm stool. Other probiotic pet supplements made his stool even softer. This is the first probiotic pet product that has actually helped firm his stool. He has only been on it for a few weeks, but we are already so impressed.

FAQ

Questions, answered

Still unsure? Ask Mikvah, or reach out. We’re always an email or call away.

How long does it take to see results?

Every pet is different, but many pet parents notice improvements within 2-30 days of consistent daily use. For deeper gut healing, immune balance, and long-term wellness support, we recommend giving the products at least 60–90 days.

Can I use this with my pet’s current food or medication?

In most cases, yes. Myco Pet supplements are designed to work alongside your pet’s existing routine and can be mixed directly with food. We have not found any contraindications with medications. If your pet has a medical condition, we always recommend speaking with your veterinarian first.

Is this safe for both dogs and cats?

Yes. All our products are formulated for both dogs and cats. Dosage is adjusted based on your pet’s weight and needs.

How do I serve the supplement?

Simply mix the recommended amount into your pet’s food 1-2x daily. For sensitive pets, you can start with a smaller amount and gradually increase to the full serving over several days.

What if my pet is a picky eater?

Many pets adjust easily when introduced slowly. Start with a smaller amount mixed into wet food, raw food, broth, or a favorite topper to help with acceptance.

Know that if they're a picky eater, this often is a sign that they have an imbalance in their gut microbiome. Try the Gut & Immunity+ supplement to help with this.

Also, our serving size is soooo tiny because we don't add any fillers, artificial ingredients or preservatives, so palatability is almost never an issue.

Can puppies and kittens use this?

Yes, but we recommend using age-appropriate formulas like our Puppy & Kitten Formula when possible. Always follow serving guidelines based on age and size.

Do I need to use this every day?

Consistency is key for the best results. Functional mushrooms, probiotics, prebiotics, and postbiotics work best when used daily to support long-term balance and resilience.

We always ask: if you feed your pet every day, they should also get gut supporting toppers to counteract the negative effects of the many toxins in our food system these days.

Is this a probiotic?

All our supplements include 18 different species of probiotics, but it goes beyond that. Our formulas combine probiotics, prebiotics, postbiotics, functional mushrooms, colostrum and targeted nutrients to support the gut-immune axis and root-cause wellness.

What makes Myco Pet different from other pet supplements?

We focus on root-cause wellness, not symptom masking. Our formulas combine functional mushrooms, probiotics, microbiome support, and human-grade ingredients designed to restore balance, strengthen immunity, and support whole-body vitality.

Can I use multiple Myco Pet products together?

Yes. Many pet parents combine products depending on their pet’s needs. For example, Gut & Immunity+ pairs well with Lean Mass+ and the PROTECT Spray for both internal and external support.

Can I give my pet too much?

Thankfully, we have no evidence that suggests your pet can overdose on this. In fact, some pets are using 4,6 and 10 doses per day with no negative side effects!

We like to say, it's very unlikely you can give too much, but you CAN give too little! So if you're not seeing the results you want, your pet likely just needs a little bit more.
