Stop the Scratching. Start the Relief.
9 active ingredients working together to target the root causes of allergy flare-ups, not just mask the symptoms.
Itch Relief
Quercetin acts as a natural antihistamine while turmeric calms inflammation — targeting allergic itching at the source.
Gut Health
Probiotics, postbiotics, and digestive enzymes support the gut-immune connection and help your dog absorb nutrients more effectively.
Immune Balance
Bovine colostrum and arabinogalactan help regulate an overactive immune response to everyday allergens like pollen and dust.
Calm & Resilience
This adaptogen helps your dog's body manage stress — which can trigger or worsen allergy flare-ups.

Why Pet Factor?
It's simple!
Comprehensive: Support that works. Pet Factor combines 9 targeted ingredients — for skin, gut, and immune health — into one daily chew, instead of juggling separate supplements.
Delicious: A treat your dog actually asks for. No bribing, no hiding it in food, no fighting to get it down.
Portable: Fits right into life with your dog. Toss a few in your bag for walks, travel, or boarding — just grab and go.
No Mess, No Stress: No cramming pills into cheese, no chasing them around the kitchen, no powder to mix into food. Just a treat they'll take right from your hand.
Ingredients
Ingredients
Pet Factor Allergy Support contains 9 targeted active ingredients, each listed with its exact dose — no proprietary blends:
Postbiotic (Yeast Culture) 250mg, Arabinogalactan (from Acacia Gum) 150mg, Ashwagandha Root Extract 100mg, Colostrum (Bovine) 100mg, Turmeric Root Powder 100mg, Quercetin 75mg, Pancrelipase (Porcine) 25mg, Lactobacillus casei 0.15 Billion CFU, and Lactobacillus fermentum 0.15 Billion CFU.
Alongside the actives, Pet Factor uses a short list of whole-food and functional ingredients to bind the chew and make it something dogs actually want to eat: organic sweet potato root powder, apple pectin, flaxseed oil, beef liver powder, and natural flavor. No fillers padding out the label — everything on it does something.
Pet Factor chews contain no artificial colors and no synthetic dyes.
Directions
Give 1 chew per 25 lbs of body weight daily.
Benefits
Pet Factor Allergy Support works from the inside out. Quercetin acts as a natural antihistamine while turmeric helps calm inflammation, targeting the itching and irritation at the source rather than just masking it. At the same time, probiotics, postbiotics, and digestive enzymes support the gut-immune connection — since roughly 80% of a dog's immune system lives in the gut, that's exactly where daily support matters most.
Bovine colostrum and arabinogalactan help regulate an overactive immune response to everyday triggers like pollen and dust, while ashwagandha supports your dog's ability to manage everyday stress — which can trigger or worsen flare-ups on its own. The result is one daily chew that supports skin, gut, and immune health together, instead of juggling three separate products to cover the same ground.

“I love that owners can see exactly what they're giving their dog”
"What I appreciate most about Pet Factor is the transparency — every ingredient is listed with its exact dose, not hidden in some vague proprietary blend. Quercetin, turmeric, postbiotics — these are ingredients I'd genuinely recommend to a client dealing with a dog who won't stop scratching, and I like that owners can see exactly what they're giving their dog."

Frequently Asked Questions
How much should I give my dog?
Dosing is based on weight — one chew per 25 lbs of body weight daily. Under 25 lbs: 1 chew/day. 25–50 lbs: 1–2 chews/day. 50–75 lbs: 2–3 chews/day. 75+ lbs: 3–4 chews/day.
Is this safe for all breeds and sizes?
Pet Factor Allergy Support is formulated for adult dogs of all sizes, dosed according to weight. It hasn't been evaluated for use in pregnant or breeding dogs. If your dog has an existing health condition or is on other medication, check with your vet before starting anything new — same advice we'd give for any daily supplement.
My dog is picky — will he actually eat this?
It's a soft chew most dogs take right from your hand like a treat, no hiding it in food required. If your dog won't take to it, you're covered by our 30-day guarantee.
What if my dog has food allergies? What's actually in it?
Worth knowing upfront: this formula contains beef (beef liver powder), dairy (bovine colostrum), pork (a porcine-derived digestive enzyme), and soy (soy lecithin). If your dog has a known sensitivity to any of those specifically, talk to your vet before starting. It does not contain corn or wheat, and has no artificial colors or dyes.
Can I give this alongside other medications or supplements?
We'd recommend checking with your vet, especially if your dog is currently being treated for allergies or another condition — that's true of introducing any new daily supplement, not specific to this one.
How long until I see a difference?
It varies by dog. Consistency matters most — daily use as part of a routine is how the ingredients do their work over time, and skipping days is the most common reason owners don't see the change they're hoping for.
What's your return policy?
30-day money-back guarantee. If it's not working out for your dog, we'll refund you.
