Tear stains don't come from the outside. They come from the inside.
Your dog's body produces porphyrin — an iron-rich compound that flows out through tears every day. On light fur, it meets air and turns brown.
It's not that you haven't tried hard enough. It's that nothing you've been given was built for what's actually causing the stain. And as long as tears flow, porphyrin comes with them. Tomorrow. Next month. The cycle doesn't stop on its own.
If the problem starts inside your dog's body, the solution has to start there too. That's the idea behind PetCore's Porphyrin Defense Complex — a blend of 14 ingredients formulated to support healthy tear composition from within.
Most tear stain products sit on the surface. They wipe, bleach, or rinse what's already there. But they can't influence what your dog's body is producing internally. Fresh porphyrin flows out through tears every single day.
The Porphyrin Defense Complex was designed to work from the inside — supporting the internal processes that influence tear composition, eye health, and oxidative balance.
Helps support a healthy response to oxidative stress — the process that turns porphyrin brown on your dog's fur.
Helps support healthy tear composition and overall eye wellness.
Helps promote a balanced microbiome — because what happens in the gut directly influences what shows up in the tears.
These aren't random ingredients thrown into a jar. Each one was chosen to support a specific part of the internal process that contributes to tear staining.

Antibiotic-free formula safe for daily, long-term use.

Chestnut Extract
Your dog's tears contain porphyrin — an iron-rich compound that turns brown when it hits fur and meets air. Chestnut Extract is rich in natural antioxidants that support your dog's healthy response to this oxidative process. Where wipes never could.
Olive Leaf Extract
Contains oleuropein — one of nature's most studied antioxidant compounds. Supports a healthy skin and coat environment from the inside, helping your dog maintain the clean, balanced conditions that stain-prone breeds need. No antibiotics. No harsh chemicals.
Lutein
The same carotenoid eye doctors recommend for human eye health — now formulated for your dog. Concentrates naturally in eye tissue, providing daily antioxidant protection for breeds that need it most.
Prebiotic Blend
What happens in the gut directly influences what shows up in the tears. This blend feeds beneficial bacteria, promotes a balanced microbiome, and supports the internal wellness that surface products can never reach.

PetCore works from the inside out — not overnight. Here's what to expect over the next 6 weeks with consistent daily use:
I used to dread people holding her because the first thing they'd say was "what's wrong with her eyes?" Nothing was wrong. She just had stains. I tried every wipe and wash out there and nothing lasted more than a few hours. About five weeks into PetCore I noticed the new fur growing in was completely white. My mom actually said "she looks like a different dog." That was the moment for me.
Jessica M. - Maltese
Three years. I tried the wipes, the special food, filtered water, coconut oil, Angel Eyes — honestly I'd lost count. I almost didn't order this because I thought it'd be another waste of money. Took about three weeks before I noticed anything and then it just kept getting better. Look at his face now. I actually cried. I'm not even embarrassed to say that.
Amanda R. - Shih Tzu
I'd honestly given up. My vet told me it's just something that happens with her breed and to stop worrying about it. I wasn't even looking for something when I found PetCore. Figured I'd try one more thing. By week four the staining around her mouth was lighter and by week six it was almost gone. I really wish I'd found this sooner instead of just accepting it.
Megan L. - Shih Tzu
I was wiping Coco's face three times a day. Every morning, every afternoon, every night before bed. It was exhausting and nothing was changing. A friend told me about PetCore and I figured why not. It's literally just a scoop in her food. About a month in I realized I hadn't wiped her face in days and it still looked clean. That was wild.
Nicole T. - Bichon Frise
I bought it for my Frenchie but honestly my Persian needed it more. I was cleaning her face every single day with cotton pads and it never stayed clean for more than a few hours. I started giving it to both of them. Same jar. Same scoop. Within about six weeks both of their faces looked noticeably better. I didn't think one product would work for both but here we are.

60-Day Risk-Free Guarantee
You've spent money on things that didn't work. We get it. That's why every jar of PetCore comes with a 60-day money-back guarantee — no questions, no hassle, no risk. If you don't see a difference, you get a full refund. Simple as that.
PetCore is salmon flavored and designed to mix into wet or dry food. Most pets don't even notice it's there. If your pet is extra picky, try mixing it with a small amount of wet food or a treat they already love. And if it still doesn't work — every jar is backed by our 60-day money-back guarantee.
Most pet owners see a visible difference in 4–6 weeks with consistent daily use. You won't notice changes day to day — but take a photo on Day 1 and compare it at Week 4. That's when it clicks. The formula works from within, so it takes time to show on the outside.
PetCore is antibiotic-free and formulated with natural ingredients including Chestnut Extract, Olive Leaf Extract, and Lutein. No tylosin. No harsh chemicals. No artificial colors or preservatives. Safe for daily, long-term use. If your pet is on medication, we recommend checking with your vet before starting — we're happy to send the full ingredient list. Email us at care@getpetcore.com.
Most tear stain supplements are just relabeled topical ingredients in a chew — 3 or 4 generic vitamins with no real formulation behind them. PetCore was built from scratch with 14 ingredients specifically chosen to support healthy tear composition from within. That's why the formula includes a Porphyrin Defense Complex — not a random multivitamin with a tear stain label on it.
Yes. PetCore is safe for puppies and adult dogs. Many tear stains start during the teething phase around 4–8 months — and supporting your puppy's internal wellness early can make a real difference. Use the same dosage guide based on your puppy's weight.
PetCore supports your pet's internal wellness on an ongoing basis. If you stop, staining may gradually return over time as porphyrin continues to be produced naturally. Most pet owners who see results choose to keep PetCore as part of their daily routine — one scoop a day is a lot easier than going back to wiping 3 times a day.
Yes. Keep your normal routine during the first few weeks — PetCore is building support from the inside. As you start to see changes, you'll naturally reach for the wipe less. Most pet owners significantly reduce or stop wiping by week 6.
Every jar comes with our 60-Day Money-Back Guarantee. If you don't see a difference, email care@getpetcore.com for a full refund. No questions asked.
