“I stopped having people over. Sounds dramatic, but every chair had hair on it and I was embarrassed. Two months on this and my sister sat down last weekend in black jeans and got up clean. I actually invite people again. That’s what I paid for.”

Some shedding is. A dog that leaves hair on every surface, every day, all year round is not just "a heavy shedder" — that pattern usually means the hair is releasing before it should. Hair is built from keratin, sulfur amino acids and zinc. When those run short, the follicle can't hold the strand, and it drops early. That's what we target.
Most shedding products work on the outside — brushes, sprays, deshedding shampoos. They remove hair that's already loose. PetFormulary works one step earlier: it delivers the building blocks the follicle needs to anchor each hair properly. Stronger anchoring means less hair released, which means less hair on your couch, your clothes and your car.
Give it 8 weeks. A dog's coat cycle simply doesn't turn over faster than that, and any product promising results in a week isn't being honest with you. Most owners notice the first drop in loose hair around week 3 to 4 — less on the brush, less on dark clothing. The full difference shows once the coat has cycled through, at 8 to 12 weeks. This is why we recommend the 3-bottle protocol.
One full dropper (2 ml) per day, straight onto your dog's food. Same dose for every dog, every size — no measuring, no weight charts, no pills to hide. It's flavoured to taste like food, so most dogs eat it without noticing. One bottle is a 30-day supply.
Hydrolyzed keratin, sulfur amino acids and chelated zinc. Hydrolyzed means broken down into fragments small enough to absorb — that's why we made it a liquid instead of a chew. Chelated zinc is the bound form, absorbed several times better than the cheap zinc oxide used in most coat supplements. No fillers, no sugar, no artificial preservatives.
Yes — all breeds, all sizes, puppies and seniors. Every batch is third-party lab tested. If your dog is on medication or being treated for a skin condition, check with your vet first, as you would with any supplement.
Try it for 60 days. If your dog is still shedding the same, email us and we'll refund you — you don't need to send the empty bottle back. Subscriptions can be paused, rescheduled or cancelled from your account in two clicks, with no phone call and no minimum term.

“Honestly I expected nothing. We’d done the deshedding shampoo, the fancy brush, the vet’s food. This is the first thing that changed anything. Week three I noticed it, week eight my husband noticed it — and he never notices. Our lab is 9 and still drops less than she did at 4.”
“I’m a contractor, my truck was a rolling hair ball and so was every shirt I owned. Around week four the brush started coming out half as full. Now I vacuum the truck twice a month instead of twice a week. Wish someone told me it was a nutrition thing.”

Have Questions About PetFormulary?
Everything you need to know before you try it.
Yes — the mechanism is the same in every dog. Huskies, German Shepherds, Labs and Goldens shed more because they carry far more hair, not because their follicles work differently. Heavy shedders usually notice the biggest change, simply because there is more hair to keep in the coat in the first place.
A brush removes hair that has already let go. That is cleanup, and you have to do it again tomorrow. PetFormulary works one step earlier: it gives the follicle the material it needs to hold each hair in place, so less hair comes loose to begin with. Most owners still brush their dog — just far less often, and with far less coming off.
It reduces it — it does not cancel it. Coat cycles are driven by daylight and temperature, and no supplement changes that. What it does change is how much hair releases during the cycle, and whether that hair ends up on your couch or stays in the coat until you brush it out.
It is flavoured and food-based, so it mixes into wet or dry food without the strong smell that makes most dogs walk away from oils. If yours still refuses it, that counts as the product not working for you — the 60-day guarantee covers exactly that.
In most cases yes — keratin, sulfur amino acids and zinc are nutrients, not drugs. If your dog is on prescription medication or currently being treated for a skin condition, check with your vet first, as you would before adding any supplement.
Yes. Every dog gets one full dropper (2 ml) a day regardless of size, and one bottle is a 30-day supply for one dog. Two dogs means two bottles a month, so the 3-bottle bundle covers a two-dog household for about six weeks — most multi-dog owners go straight to it.
No chicken, beef or fish protein, and no wheat, soy, sugar or artificial preservatives. If your dog is on a limited-ingredient diet, the full ingredient list is on the label above — worth a quick read before you order.
Then you get your money back. Give it 60 days. If you are not seeing less hair around your home, email us and we refund the full order — you do not need to send the bottle back, empty or not.
