Medicinal mushrooms – natural immune activation
K9 Immunity Plus™ contains six organic mushrooms: Reishi, Cordyceps, Maitake, Shiitake, Agaricus blazei, and Turkey Tail.

I have been giving it to my Schnauzer as a preventive treatment for years. And he has absolutely no health issues. He likes the taste, and it’s easy to give him. I think it’s a great product.

Dávám to svému psovi po operaci páteře, dokáže to zázraky!!!

Lo scorso novembre Happy è stato diagnosticato con cistite, e l’ecografia (UH) ha mostrato una lesione di 4×7 mm sulla parete della vescica. L’infiammazione si è risolta immediatamente dopo un ciclo di farmaci, e Happy ha reagito bene, dato che era solo la seconda volta nella sua vita che assumeva un vero medicinale, all’età di 8 anni. Tuttavia, la lesione sulla vescica era molto preoccupante, e dopo un’attenta ricerca ho deciso di dargli il K9 Immunity Plus.
Dopo un mese e mezzo siamo tornati per un controllo, e non c’era più traccia dell’ispessimento! Secondo l’ecografia, tutto è a posto con Happy. L’ecografia ha confermato che la sua vescica è in buone condizioni.

Der Tierarzt gab meinem Hund eine Prognose von 3 Monaten, als der Knochenkrebs diagnostiziert wurde. Seit 7 Monaten bekommt er K9, und jetzt bellt er fröhlich im Garten!

Ce produit a vraiment changé les choses. Notre berger allemand de 10 ans a été diagnostiqué avec un hémangiosarcome, et on ne lui donnait plus que quelques semaines. Depuis qu’il prend le K9 Immunity Plus tous les jours, il a retrouvé l’appétit, il bouge plus, et il a l’air bien mieux dans ses pattes.
On sait pas combien de temps on a encore avec lui, mais au moins il vit mieux, et chaque jour compte.
