K9 INU® – real immune support for real challenges
When your dog faces illness, weakness, or even cancer, you don’t just want to ease the symptoms. You want to strengthen their body from the inside out. K9 INU® gives you a natural way to support their immune system every single day.
This unique supplement combines six medicinal mushrooms in one powerful formula. Together, they provide daily immune support for dogs. Not only does K9 INU® promote recovery, but it also helps your dog stay resilient, energetic, and balanced for the long run.
Why mushrooms? Because balance matters
Unlike many immune boosters that only stimulate the system, K9 INU® goes further. It helps restore balance.
Medicinal mushrooms regulate the immune response. They activate it when needed and calm it when it becomes overactive. As a result, your dog gets the right kind of support – no more, no less.
This smart balancing act is called immunomodulation. And yes, it’s one of the reasons mushrooms have become a trusted tool in natural healing.

You can turn to K9 INU® when your dog faces serious health challenges, or simply needs stronger daily support. Let’s explore the most common situations where this supplement can make a big difference.

Do any of these sound familiar?
“My dog had cancer. He’s stable now, but I want to protect his progress.”
“She’s still in treatment, and I want to give her the best shot at recovery.”
“He gets sick so easily. I need something that really works.”
“She’s older but full of life – and I want to keep it that way.”
“He bounced back once, and I don’t want to go through that again.”
If any of these stories feel like your own, you’re not alone.
K9 INU® was made for situations just like these. Because your dog deserves more than short-term fixes – they deserve lasting strength and wellness.

Non l’ho comprato per una malattia specifica, ma per rafforzare il sistema immunitario del mio cane e prevenire eventuali problemi. Lo aggiungo al suo cibo e lo mangia senza problemi. Da quando lo uso, è pieno di energia e vitalità!
Consiglio assolutamente questo prodotto!

Ein wirklich ausgezeichnetes Produkt! Ich gebe meinem Hund schon seit Monaten K9 Inu, und die Veränderung ist einfach unglaublich. Er hat viel mehr Energie, fühlt sich sichtlich besser, und sein Immunsystem ist deutlich stärker. Man merkt, dass es ihm richtig guttut.
Ich bin mit den Ergebnissen sehr zufrieden und kann es nur jedem empfehlen, der die Gesundheit seines Hundes fördern möchte!

Last December, it was determined that my dog has no blood clotting. We spent a week in intensive care. In May, he collapsed and had to undergo emergency surgery. Again, we spent another week enjoying the hospitality of the intensive care unit. Hemangiosarcoma. The doctor gave him 1-2 months without chemo. The family gathered and decided to seek an alternative treatment.
This is how we found K9 INU. It’s been 5 months now, and he’s bursting with energy. I am very grateful that I discovered this product.
Special thanks to Gina, who recently went above and beyond to solve an issue.

Al nostro cane, Giorno, hanno diagnosticato un linfoma. Il veterinario ci ha detto che non si poteva operare e che gli rimanevano solo pochi mesi. Non ci siamo arresi e abbiamo cercato un’alternativa: così abbiamo scoperto K9 Inu.
Da più di 7 mesi lo usiamo e Giorno sta benissimo! È pieno di energia, proprio come quando era cucciolo. Il veterinario non riesce a spiegarsi cosa sia successo: il tumore è sparito!
Grazie mille per questo prodotto fantastico! Lo consiglio a tutti!

In May, our 9-year-old Komondor was diagnosed with a heart base tumor. At that time, the prognosis was 1-2 months. In June, we discovered K9 Inu. Since then, he has been taking it daily. Now it’s December, and he is alive and doing well.

Un anno fa, il mio cane meticcio segugio di 12/13 anni, ha affrontato un’operazione molto seria, rimozione di un emangiosarcoma retroperitoneale, rimozione di un rene e uretere. L’emangiosarcoma può essere molto aggressivo e metastatizzare a organi distanti, per questo motivo, dopo un mese e mezzo, Lucky ha iniziato la chemioterapia metronomica (era troppo debole per subire quella tradizionale). Ho iniziato immediatamente a dargli K9 InuFactor e K9 Inu, scoperti casualmente su internet,per rafforzare il sistema immunitario, ridurre gli effetti collaterali della chemioterapia e soprattutto con la speranza di ridurre il rischio di neoformazioni .
Cosa posso dire? E’ passato un anno dall’operazione e 10 mesi dall’inizio della chemioterapia e il nostro dolce Lucky non ha ancora avuto effetti collaterali dai farmaci chemioterapici, mangia con molto appetito, fa delle belle passeggiate, è attento e reattivo e i nostri cuori scoppiano di felicità per ogni giorno che ci viene regalato in sua compagnia.
Grazie DogHealth.com e grazie a tutto lo staff, sempre molto gentili quando ho avuto bisogno di informazioni.

Mein Hund hatte ständig irgendwas. Mal eine Ohrenentzündung, mal Durchfall, dann wieder Husten. Unser Tierarzt (ein Freund der Familie) meinte, dass sein Immunsystem wohl ziemlich schwach ist und wir da etwas tun sollten. Ich habe angefangen zu suchen – und so bin ich auf K9 INU gestoßen. Jetzt bekommt er es seit fast 8 Monaten, und seitdem ist alles anders: Er ist nicht mehr ständig krank, viel aktiver und insgesamt einfach fitter.
Für uns wirkt das wirklich – und wir bleiben definitiv dabei.
(Übrigens, unser Tierarzt meinte: „Nichts Neues unter der Sonne, aber dieses Produkt ist echt gut zusammengestellt.“)
