K9-B1 Gut-to-Skin Daily Defense

Stop the Apoquel Cycle - Heal Your Dog's Gut Instead

If your dog won't stop licking their paws or scratching at 3 AM, the problem isn't their skin. It's their gut. 70% of your dog's immune system lives in their intestines. When gut health collapses, the immune system misfires - attacking harmless things like grass and pollen. Apoquel blocks the itch, but doesn't stop the inflammatory fire underneath. That's why you're trapped in the prescription cycle.

✔ Stops Paw Licking & Scratching From the Root Cause
Rebuilds gut balance so the immune system stops overreacting - ending the itch naturally, not just suppressing it.

 

✔ Clears Hot Spots, Yeasty Ears & Skin Infections
Healthy microbiome = calm immune response. Chronic inflammation and secondary infections disappear.

 

✔ Premium, Research-Backed Probiotic Strains
Not grocery-store probiotics. Targeted strains studied for immune modulation in dogs with allergies.

 

✔ Easy to Give, Loved by Dogs
Tasteless powder that mixes into meals. Even picky eaters won't notice - but you'll see results in weeks.

My Golden Retriever was trapped in the Apoquel cycle—constant paw licking at 3 AM, hot spots, and expensive vet visits every month. After 5 weeks on K9 BioLabs, the scratching stopped, her skin cleared up, and we've been able to cut her Apoquel dose in half. I finally have hope we can get her off meds completely!

questions? we’ve got answers.

Everything you need to know, right at your fingertips.

Will this help my dog's chronic allergies and itching?

Title

Yes! Chronic itching is often driven by gut imbalance, not just environmental allergens. K9-B1 is formulated with immune-modulating probiotics to restore microbiome health and calm the inflammatory response causing the itch - so you can expect less scratching, fewer hot spots, and healthier skin.

How long before I see relief from yeast symptoms?

Title

Most dog parents begin to notice improvements within 2–3 weeks-odor starts to dissipate, and scratching calms down. For best results, we recommend giving Ear Fresh consistently for 6–8 weeks to fully rebalance the ear environment.

My dog gets recurring yeast ear infections—can Ear Fresh help reduce the frequency?

Title

Absolutely. Ear Fresh targets yeast imbalance at its source, helping strengthen natural defenses and reduce the likelihood of future flare-ups. Many customers report fewer infections when using it daily over several months (though you should still consult your vet for active or severe cases).

Is there any risk of my dog overdosing on their supplement?

Title

Our supplements are carefully balanced with your dog’s weight in mind, so we always recommend that you stick to the suggested dosage.

In the event that your dog accidentally consumes more than the recommended dose, consult your vet as soon as possible.

What will my dog's supplement taste like?

Title

Our supplement is crafted with a naturally mild and palatable flavor that blends seamlessly with your dog’s daily meals. Made from all-natural, human-grade ingredients, it’s free from fillers, artificial additives, and common allergens - and 100% safe for canine consumption.

 

If your pup happens to be picky, simply mix the powder into their food or combine it with a favorite snack like plain yogurt or dog-friendly peanut butter.

 

And if after that they still don’t take to it, we proudly stand behind our 60-day satisfaction guarantee - simply return the product for a full refund.
