Extensive Research & Development
MC-07’s formula was refined over years with science-backed ingredients at effective amounts to support a healthy, happy life.
Best for dogs who itch and lick
“This is a very strong probiotic blend that's safe and effective for all dogs. I use it in practice and my clients see fantastic results.”
“When I see recurring allergies, upset digestion, and dull coats—my focus starts in the gut.”
As a practicing veterinarian, I’ve seen hundreds of dogs cycling through the same frustrating pattern: itching, paw-licking, loose stools, and lackluster coats. In almost every case, the real problem isn’t on the surface—it starts deep in the digestive tract.
1. Allergies and Immune Overload
Chronic itching, red paws, and ear flare-ups are often the immune system’s cry for help. When the gut is unbalanced, the immune response goes haywire—turning harmless triggers like pollen or food into full-blown allergic reactions. MC-07 helps restore immune balance by rebuilding the gut barrier and calming that constant overreaction.
2. Loose Stools and Sensitive Stomachs
Many owners overlook how frequent soft stools or bloating indicate an unhealthy microbiome. MC-07 combines prebiotics, probiotics, and digestive enzymes to correct that imbalance—allowing dogs to absorb nutrients properly and reduce gas, diarrhea, and discomfort within days.
3. Skin and Coat Health
A glossy coat and calm skin start with efficient nutrient absorption. When inflammation in the gut drops, so does the inflammation under the skin. Over time, I see coats regain their shine, shedding decrease, and dogs appear visibly more vibrant and comfortable.
I now recommend MC-07 as part of my long-term wellness plans for dogs with recurring skin, allergy, or digestive concerns. It’s gentle, science-backed, and easy for owners to use daily. A few drops with breakfast can make a world of difference.

Let customers speak for us
absolutely most effective product I have ever purchased my dog. He is just a very year-old. He has had irritable bowel syndrome with extreme diarrhea and bloody throws the entire time I’ve had him. He had never gotten a break besides getting medication from the vet and it would still be very frequent very stressful bowel movements and incapable of holding for periods of time with this medication I have had absolutely no issues with that. He is able to sleep through the night without having to have accidents without having blood and installed without any type of discomfort or weight loss of any kind absolutely amazing no bad medication no diet change absolutely nothing has ever worked to this this with the best unexpected surprise, truly grateful
Works better than any chew we tried before.
My dog Axel was having digestive issues and nothing seemed to work. Sometimes pumpkin worked for a week and then back to an upset stomach. 14 days on MC-07 Daily Probiotic and his itchy skin has cleared up, and his digestive track has fixed itself. This product has done exactly what it said it was going too. I cannot thank Riley&Co enough. Thank you!
I've been giving this to my Riley, Bedlington Terrier, age four, for one week. I will return once I evaluate progress for one month. Keeping my fingers crossed this helps poor Riley! Thank you, Kathy Van Zant
I wanted to wait to see the results before posting a review. I have tried sooooo many products for my dogs skin issues. This is the ONLY product that has made a significant difference. My dog hasstopped chewing on his skin, his fur is soft and silky again and he seems so much more comfortable!! I did not think there was really a product out there that could alleviate his skin condition, but this has been a blessing 🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🐶 🐕🦺

The Hidden Culprit Behind Your Dog's Allergies
The gut bacteria in your dog's digestive system directly impacts their immune system, organ function, digestive system and allergy responses. Most dogs don't have the right balance of beneficial bacteria they need.
But here's the problem: 93% of dog probiotics don't work because they're destroyed by stomach acid before reaching the intestines. This leaves your dog suffering with chronic allergies and recurring ear infections that even expensive vet visits can't solve.
Your dog's immune system is continuously triggered by harmful gut bacteria that create inflammation and overreactive responses to normal triggers. Without proper gut support, allergy symptoms worsen over time.
⭐️⭐️⭐️⭐️⭐️
"Easy to mix and no smell. My shepherds constant itching is gone"
Introducing: The Gut-Allergy Protection Protocol
We've created a specialized probiotic to tackle the real cause of your dog's chronic allergies. Meet Riley & Co MC-07 Probiotic. It's packed with Bacillus Coagulans and revolutionary Spore Armor Technology that survives stomach acid and reaches the intestines alive.
Why not just use any dog probiotic?
Most probiotics are killed by stomach acid, resulting in minimal absorption and virtually no relief. That's why we created Riley & Co MC-07 Advanced Probiotic. Our direct-delivery method bypasses the harsh stomach environment entirely, dramatically increasing effectiveness.
This means your dog's immune system can finally receive relief from harmful bacterial triggers, reducing inflammatory responses and stopping recurring ear infections.

About This Product
About This Product
MC-07 Advanced Probiotic Drops
MC-07 Advanced Probiotic Drops are a veterinarian-reviewed formula created specifically to help dogs suffering from allergy-related itching, licking, skin irritation, digestive issues, and sensitivity flare-ups by restoring balance to the gut—the root system that controls your dog’s immune and allergy response.
Why It Works
A dog’s gut microbiome directly influences how their body reacts to allergens like pollen, dust, grass, and food proteins, and when the gut lacks healthy bacteria, allergies intensify and symptoms spread. MC-07 uses a high-potency blend of probiotics, prebiotics, and postbiotics to strengthen the gut barrier, support immune balance, and reduce the overreactions that cause itching, paw chewing, head shaking, red skin, yeasty odors, bad gas, soft stools, and low energy.
The MC-07 Advantage
Unlike antihistamines or medicated shampoos that only mask symptoms temporarily, MC-07 targets the underlying gut imbalance driving persistent allergy discomfort. The advanced liquid delivery system ensures fast absorption, the clinically studied strains help calm inflammation and stabilize immune activity, and the nutrient-rich formula supports healthier skin, smoother digestion, stronger immunity, and overall comfort.
Why Vets Recommend It
Veterinarians recommend MC-07 because allergies often start in the gut, not the skin, and improving gut health naturally reduces the frequency and severity of flare-ups. Dogs using MC-07 commonly experience decreased itching, less paw licking, fewer ear issues, reduced yeast, more consistent stools, improved skin appearance, and noticeably better comfort during allergy season.
How to Use
Simply add the drops to food once per day, allowing the formula to absorb quickly and deliver ongoing support for allergy relief, immune balance, digestive health, and long-term skin comfort.

If my dog could write a review, he’d probably give this product two paws up and a very enthusiastic tail wag. Since starting daily, his stomach symphony of chaos has finally gone quiet. No more surprise butt-trumpets in the middle of the night. No more "guess-that-smell" contests. It's been a peaceful, fragrant-free household!

It's great and worked wonders. My ragdoll kitten was given antibiotics at the age of 3 weeks. When he transitioned to solid foods his stomach was very sensitive to anything, even tiniest difference in food was giving him soft poo. After 3 days of using this probiotic everything settled. It's 2 weeks now. My kitten eats verity of foods wet and dry in different combinations and his poo is not soft anymore. He puts on weight and is growing as a healthy kitten. Honestly, after 4 weeks of soiling himself and me having to give him bath sometimes twice a day it's a huge relief.

My sister raved about these drops and I had to see for myself! I tried hers before committing and now I will absolutely be buying my own (and some to replace hers). My dog loves the taste and it has made a huge difference in digestion. No more picking up watery messes!
