My lab had been scratching herself raw for two years. Apoquel worked until it did not.
Eight weeks on these chews and the constant scratching has finally calmed down.

My poor guy chewed his paws bloody every allergy season. Been giving these daily and the paw-licking has dropped off a lot. He seems so much more comfortable.

Bought these after we spent a fortune at the vet on allergy meds. Skeptical at first, but his belly is not red and angry anymore and the scratching has really settled.

My vet had us on Cytopoint injections every month. Wanted off the drug treadmill. These chews have kept my girl comfortable without a single shot since.

I kept forgetting the powders and drops so they just sat in the cupboard. She takes this like a treat in 5 seconds, so I actually remember. The itching is way down now.

These scars have been part of my face since I was 16. Almost 20 years of just accepting them. I still see them when I look in the mirror but I don't immediately zoom in on them anymore. That mental shift alone has been life-changing.
Your Dog's Itch Journey
Watch the scratching ease in the first weeks and the leaky gut rebuild over the months with Biolgical soft chews.
Week 1
Less Scratching
In the first week many owners notice less scratching, licking and chewing as the gut begins to calm.
Week 2
Calmer Skin
By week two the skin looks less red and inflamed as the flare-ups settle.
Month 2
Coat Recovers
By month two the coat fills back in, hot spots fade, and your dog is visibly more comfortable.
Month 3 & Beyond:
Gut Rebuilt
With daily use the leaky gut lining is rebuilt, the immune overreaction settles, and the itch stays away for good.
3-Step Daily Protocol
Give
Give one soft chew a day. Most dogs take it straight from your hand like a treat.
Feed Daily
Feed daily with or without food — one chew covers most dogs (follow the weight chart on the bag).
Watch Them Thrive
Give every day for 6–12 weeks.
As the gut lining seals, the food and pollen leaking into the blood stop firing the itch — most owners see real change by week 3–6.

How it Works
Follow your progress and see what's ahead on your path to success
Repair the Gut Lining
Bovine colostrum delivers the growth factors that rebuild the gut lining. Allergy drugs mask the itch but never fix what is leaking underneath.
Calm the Immune Overreaction
Turmeric and quercetin settle the allergic response while probiotics rebalance the gut immunity that drives the flare-ups.
Reseal the Leaky Barrier
With daily use the gut wall reseals, so undigested food and pollen stop leaking into the bloodstream to trigger the itch.
Stop the Itch at the Source
With the gut sealed and the immune system calm, the chronic itch fades — coat and skin recover from the inside out.
What's Actually In It
Four evidence-backed actives — bovine colostrum, probiotics, omega-3 and turmeric — formulated to repair the leaky gut lining and calm the allergic itch.
BOVINE COLOSTRUM (20% IgG)
BOVINE COLOSTRUM (20% IgG)
Immunoglobulins and growth factors that rebuild the leaky gut lining and calm an over-reactive immune system.
5 BILLION CFU PROBIOTICS
5 BILLION CFU PROBIOTICS
Live cultures that restore healthy gut flora — where ~70% of immunity lives.
OMEGA-3 FISH OIL
OMEGA-3 FISH OIL
EPA and DHA that help calm the inflammation behind the itch and support healthier skin and coat.
TURMERIC + QUERCETIN
TURMERIC + QUERCETIN
A natural anti-inflammatory and 'nature's antihistamine' that help settle the allergic response.
Chronic itch is the #1 reason dogs land at the vet
You're not alone. Allergic itch affects up to 1 in 4 dogs. Vets reach for Apoquel and Cytopoint, but those only mask the signal — the leaky gut driving it is never addressed so the itch returns the moment you stop. Biolgical works underneath — repairing the leaky gut lining so the itch stops at its source.
Biolgical vs Vet Allergy Meds
While vet allergy meds cost hundreds a year, only mask the itch, and carry real side effects, Biolgical repairs the leaky gut underneath — for a few dollars a day.

FAQ's
Is it safe to give my dog every day?
+
Yes.
It is a drug-free daily chew of food-grade ingredients — bovine colostrum, probiotics, omega-3 and turmeric — with none of the side effects of allergy drugs like Apoquel or Cytopoint.
How long does it take to see results?
+
Every dog is different.
Most owners report noticeably less scratching within the first few weeks of daily use, with the biggest change over 6–12 weeks as the gut lining rebuilds.
What if my dog has been itchy for years?
+
Even long-standing allergies respond, because the gut lining is always renewing.
Chronic cases take longer (10–12 weeks) but the itch still calms as the leaky gut seals and the immune system settles.
Can I give this alongside my dog’s other medication?
+
Yes. The chews are drug-free food-grade ingredients and pair safely with most medications. If your dog is on prescription meds, check with your vet.
Will this help paw-licking and ear infections too?
+
Yes. Paw-licking, recurring ear flare-ups and hot spots are classic signs of the same leaky-gut allergic cycle.
As the gut seals and the immune system calms, most owners see all of these ease together.
How long does one bag last?
+
Each bag holds 60 soft chews — a full one-month supply for most dogs (follow the weight chart on the bag).
Is this safe for puppies and senior dogs?
+
Yes. It is drug-free and gentle enough for puppies and seniors. Introduce it with food for the first few days if your dog has a very sensitive stomach.
Can I give this to any breed?
+
Yes. It is safe for all breeds and sizes. Dose by weight using the chart on the bag.
What are the ingredients?
+
Bovine colostrum (20% IgG), a 5-billion-CFU probiotic blend, omega-3 fish oil (EPA and DHA), turmeric and quercetin, in a grain-free soft chew dogs love.
Do you offer a money-back guarantee?
+
Absolutely. If your dog is not calmer within 30 days, request a full refund — no questions asked.
Which problems does this help with?
+
It helps with the most common signs of allergic, leaky-gut-driven itch, including:
• constant scratching and licking
• paw-chewing and hot spots
• recurring ear infections
• red, irritated skin and belly
• dull coat and hair loss
Give with food. This is a supplement, not a substitute for veterinary care in severe cases.
Shipping & Processing Times
+
Orders are processed in 1–3 business days.
Delivery typically takes 7–12 business days depending on your location. You will receive tracking updates by email.
Return Policy
+
If Biolgical is not right for your dog, simply request a refund within 30 days. No forms, no stress.
Can I give this with my dog’s current allergy medication?
+
Yes. You can give the chews while your dog is still on Apoquel or Cytopoint, then taper the drug with your vet as the itch calms.
The chews work underneath, on the gut.
Will it work if my dog is on a special diet?
+
Yes. The chews are grain-free and complement any diet, including hydrolyzed and limited-ingredient food. They support the gut no matter what is in the bowl.
Does this replace my dog’s allergy medication?
+
It addresses the root cause — the leaky gut — rather than masking the itch like a drug.
Many owners wean off allergy meds with their vet over time, but never stop a prescription abruptly. Work with your vet.
Can I give this with other supplements?
+
Yes, but check with your vet first if your dog is on multiple supplements.
