Vet-Formulated Relief For Scratching, Itching, Hot Spots & Paw Licking
Every ingredient in our formula is there for a reason—and backed by peer-reviewed research, not marketing fluff. We don’t hide behind “proprietary blends” or vague labels. You get a clear, transparent list of clinically supported ingredients—each included at a meaningful dose.
The natural antihistamine that stops histamine before it's released. Stabilizes the mast cells at the source — so the flood never starts.
The delivery driver for quercetin. Increases absorption by up to 5x. Without it, most quercetin passes straight through unused.
The ingredient no other allergy formula includes. Breaks the stress-cortisol loop that keeps damaging the gut and restarting the allergy cycle.
Rebuilds the gut lining that's been letting allergens into the bloodstream. Delivered in powder — never heat-pressed — so every strain arrives alive.
Retrains the immune system to stop overreacting. Doesn't suppress immunity like Apoquel — teaches it to respond proportionally to real threats.
Delivers EPA and DHA to fight inflammation through the omega-3 pathway. Directly competes with the compounds your dog's body uses to produce inflammatory responses.
Delivers GLA for skin cell membrane repair through the omega-6 pathway. Paired with salmon oil to cover two separate anti-inflammatory pathways simultaneously.
Soothes and restores the intestinal mucosal lining — the wall that's been letting allergens through into the bloodstream.
Provides the bioavailable sulfur your dog's skin cells need to rebuild keratin and collagen. The structural repair ingredient.
Enhances absorption of every other ingredient in the formula. The ingredient that makes the other 12 work harder.
Gives skin cells the replication capacity they need to form new healthy tissue. Works alongside MSM and Vitamin E as part of the skin repair crew.
Shields new skin cells from oxidative damage as they form. Without it, inflammation destroys new cells as fast as they're made.
Sends immune defenders directly into the skin — building an on-site defense system right where the allergies cause damage. Validated in a randomized, double-blinded clinical trial for canine atopic dermatitis.
Most dog allergy supplements sound the same — but there are critical differences that determine whether the ingredients actually work. Here's why ours stands out:
✅ It Targets the Root Cause
We don't just mask the itch — we fix the broken gut causing it. PetCore is the only allergy supplement built around the gut-skin axis.
✅ 80% Active Ingredients — No Filler
Standard allergy chews are up to 65% binding agents that do nothing for your dog. PetCore is a powder — every scoop delivers what's on the label.
✅ Quercetin That's Actually Absorbed
Without a carrier, your dog's body flushes most quercetin unused. We pair it with Bromelain for up to 5x better absorption — something most competitors skip entirely.
✅ The Only Formula With L-Theanine
Stress raises cortisol. Cortisol damages the gut and restarts the allergy cycle. L-Theanine breaks this loop — and no other allergy supplement includes it.
Most dog owners spend months — sometimes years — managing symptoms without ever addressing the root cause. Here's what the data actually says:
PetCore was built for the dog owner who's done managing symptoms and is ready to fix the cause.
PetCore works in stages. Here's what's happening inside your dog's body — and when you'll start to see it on the outside.
Probiotics begin rebuilding the gut lining that's been letting allergens through. Internal changes are happening before anything visible. Mild stool changes in the first week are normal — it means the formula is working.
Scratching and paw licking noticeably reduce. Skin redness calms down. First visible coat improvements begin to appear.
Full gut-immune restoration. Dramatic coat improvement. Reduced allergy flare-ups. Your dog is comfortable, calm, and protected from the inside out.

"Three years of watching her suffer and it was just… over. I couldn't believe it. My vet was skeptical but even she admits our dog looks better than she has in years."
"I cancelled my Chewy autoship. My vet was skeptical at first — she's not anymore."
"The paw chewing has stopped completely. She still licks on occasion but she's so much happier. I was super sceptical but these 100% work."
"My poor boy used to lick and nibble the skin clean off his toes. One million percent improvement in just a few weeks. He is in pain no more and his toes have never looked so healthy."
"I documented everything with photos. Day 1: red inflamed belly, bald spots on both flanks. Day 90: you would never know this dog had allergies. Every skeptic in my family is now a believer."
"She rarely pays attention to her feet anymore. No longer licking paws, scratching ears or shaking her head — it's stopped. Her coat is shiny again and all the flakes gone."
That's the most common thing we hear — and it's completely fair. Here's the honest answer: most allergy supplements fail because of format, not ingredients. A soft chew is 35–65% binding agents. The probiotics are heat-damaged during manufacturing. The quercetin passes through unused without a carrier. Your dog didn't fail the supplement. The format failed your dog. PetCore is a powder — 80% active ingredients, live probiotics, and quercetin paired with Bromelain for 5x better absorption. Same category. Completely different delivery.
Most owners notice the first reduction in scratching within 2–4 weeks. Visible coat improvement typically appears by week 6. Full gut restoration — the lasting change that doesn't reverse overnight — takes 8–12 weeks. We know that feels slow when your dog is suffering right now. That's exactly why we offer 90 days, not 30. The gut-immune axis takes time to repair. But when it does, the results last — unlike Apoquel, which returns to baseline the moment you stop.
Yes — and many owners do exactly that. PetCore addresses the root cause that Apoquel suppresses. Using both together means your dog gets immediate symptom relief from the medication while PetCore rebuilds the gut and retrains the immune system underneath. Many owners gradually reduce their Apoquel dose with their vet's guidance once they see PetCore working. Always consult your vet before changing any medication protocol.
PetCore contains 13 naturally derived ingredients — every one peer-reviewed and included at a therapeutic dose. No artificial preservatives. No synthetic binders. No chicken — one of the most common dog allergens found in most competitor supplements. No proprietary blends hiding underdosed ingredients. Mild stool changes in the first 7 days are normal as the gut microbiome begins to shift — this is the formula working, not a negative reaction. If you have specific concerns about your dog's health conditions, share the full ingredient list with your vet. Most vets who review it have no issues with a single ingredient.
We hear this a lot — and the research backs up your concern. For severe acute flare-ups, PetCore works best as a daily foundation alongside your current medication protocol, not as an overnight replacement. What it does is address the broken gut and dysregulated immune system driving the severity in the first place. Owners with the most severe cases consistently report that adding PetCore reduced their medication dependency over time — even when nothing else had moved the needle. One owner reported going from triple medication to Apoquel alone after 90 days. Give it the full timeline.
Almost universally yes. The beef liver flavor mixes invisibly into wet or dry food — your dog doesn't know it's there. No chews to spit out, no pills to hide, no peanut butter tricks, no mealtime battles. This is one of the biggest advantages of the powder format. Over 12,000 customers have confirmed compliance is not an issue. One reviewer called it "zero rejection" — their words, not ours.
Then you pay nothing. We offer a full 90-day money-back guarantee — no forms, no hoops, no restocking fees. Email us at support@trypetcore.com within 90 days of purchase, even if the jar is empty, and we'll refund every penny. We give you 90 days because we know lasting gut restoration takes time and we want you to have the full window to see real results. You have nothing to lose except the scratching.
