The Scratching Stops. The Skin Calms. The Coat Comes Back.

No, it’s closer to the opposite. A probiotic is live bacteria you’re hoping will survive and then produce something useful. A postbiotic is the useful thing itself, already produced. The bacteria did the work before it ever got in the jar. Nothing has to stay alive for it to work.

Indoles. They’re compounds gut bacteria make out of tryptophan, and they’re one of the signals that runs between the gut, the immune system, and the skin. That’s the pathway this whole product is built on. It’s also why the ingredient panel above is grouped the way it is: the postbiotic delivers indoles directly, and the tryptophan, the B. subtilis strain, and the two cofactors are there to help their gut make more of its own.

Because the gut, the immune system, and the skin aren’t three separate departments. They talk to each other constantly, and indoles are one of the things they talk with. That’s the gut-skin-immune axis. It’s also why the itchy dog with the sensitive stomach is one problem, not two.

There is a probiotic in it, one strain, and it’s on the label as “Indole Probiotic.” But it isn’t the argument. That strain was picked for one job, which is producing indoles, and it’s there to back up the postbiotic rather than carry the product. If generic probiotics have already done nothing for your dog, that’s not a mystery. You were feeding a bacteria and hoping it survived long enough to make something. The postbiotic skips that.

No. They get 150mg. One scoop.

Here’s the honest version, because you’ll figure it out anyway. The clinical research used 150mg for a medium dog. A medium dog on YH-02 gets 300mg, which is two scoops. Your 15 lb dog gets one scoop, which is 150mg, which is exactly what the research used. Not more. Exactly it.

So the “we didn’t cheap out” argument on this page is a medium-dog argument. For your dog, YH-02 is a clinically studied postbiotic at the dose that was actually studied, which is still a sentence most of the category cannot say about anything on their label. But it isn’t more, and I’m not going to let you buy it thinking it is.

The label says you may see results in 1 week, but use daily for 12 weeks for best results, and that’s what we’re going to say too.

In practice, coat and digestion tend to move earlier than skin and itch. Skin takes longer. It always takes longer. If you want a fixed date, I don’t have one for you, and anyone who gives you one is making it up.

There’s 400mg of beef liver in every two scoops, and it’s there for exactly one reason, which is that a supplement your dog won’t eat isn’t a supplement.

If they’re genuinely suspicious of anything new, start with half a serving for 5 to 7 days and work up. That works more often than people expect.

Ask your vet. Not us, and not a page that’s trying to sell you something.

YH-02 is a food topper. It is not a medication, it is not a replacement for one, and it does not treat, cure, or prevent any disease. If your dog is on something for their skin and you’re thinking about changing that, that conversation is between you and your vet. I’d rather lose the sale than have you make that call off a sales page.

Talk to your vet first, and show them the label. Every ingredient and every amount is printed on the jar, so your vet can see the whole formula in about ten seconds. Allergen note: it contains fish.

Yes. The flavor is beef liver and fish, and the omega-3 in it is fish oil. Fish is the allergen on this label. If your dog reacts to fish, this isn’t the one, and I’m not going to talk you into trying it to find out.

No. One-Time Purchase is the other tab in the box above, and it’s a real option, not a decoy. Subscribe and Save is cheaper and you can pause, skip, change the frequency, or cancel any time. If that’s not what you want, take the one-time and we’ll leave you alone.

You email us inside 30 days and we send your money back. Not a store credit. Your money.

Here’s the part I’d rather tell you than have you work it out yourself at 2am with a calculator: the label’s protocol is 12 weeks, and the guarantee is 30 days. That’s a real gap and I’m not going to pretend it isn’t. What I’d say is that 30 days is long enough to know whether your dog will eat it, whether their stomach settles, and whether anything is moving at all. If it’s done nothing in a month, you’ll know well before day 30. That’s what the window is for.

We get asked this constantly and we know why, so, plainly: we don’t sell on Amazon. If you find a Young Hound product on Amazon or eBay, it isn’t ours.
