Your dog deserves to move freely and without pain. K9 INUFlex® is a complete, natural joint support formula that makes that possible.

How to use K9 INUFlex®
Sprinkle the K9 INUFlex® powder directly onto your dog’s food once a day. Each pouch includes a scoop that measures exactly 5 grams of product, making daily dosing simple and precise.
Recommended daily dosage by weight:
- ~6 kg (13 lbs): ¼ scoop (1.25 g) – approx. 176 servings

The powder form makes it easy to customize the dose and blend it into any type of food – dry, wet, raw, or home-cooked. Unlike tablets or chews, there’s no need to worry about your dog spitting it out.

2019.10.06. Unfortunately, K9 FullFlex didn’t work for us so we gave something else, but I really like the ingredients of this one, especially the medicinal mushroom extract. We will definitely try it because he has advanced hip dysplasia on one side and arthritis on the other leg.
2019.10.19. We just started today, I have high hopes for it I admit. We’ll see what happens in a week…
2019.10.26. Dear DOG HEALTH.COM, I will try to briefly describe the effect. My Molly is a 10 year old beagle girl puppy. Unfortunately she has already developed advanced dysplasia in one leg and arthritis in the other. We have been taking all sorts of things, everything, including medication. The previous ones have helped her a lot, but we wanted to change things up a bit and try something else and I have to admit I had high hopes for K9 InuFlex.
Well the experience I’m seeing on my puppy is FANTASTIC. He runs, he runs, he’s up way more and he’s back to being the old Mollyka. We can only recommend this product because it has really worked for us even though we have only been on it for 1 week.
Thank you on behalf of Mollyka.

Hace 3 meses que se lo damos a nuestro perro y es como si lo hubieran cambiado.
Vuelve a correr, jugar y tiene mucha más energía.
¡Solo puedo recomendarlo!

Odkar K9 Fullflex ni več na voljo, dajemo to našemu psu.
(To je že tretji.)
Našemu veterinarju popolnoma zaupamo, vprašali smo ga za mnenje in izdelek nam je popolnoma priporočil.
Za nas je bilo to več kot dovolj!

Mein 13,5 Jahre alter Pudel hatte in den letzten Jahren ab und zu ein bisschen gehumpelt, doch eines Tages konnte er plötzlich nicht mehr auf seinen Hinterbeinen stehen. Der Tierarzt meinte, er sei alt und hätte Probleme mit der Hüfte und der Wirbelsäule. Er bekam Medikamente, Spritzen und Infusionen, die kurzfristig halfen, aber nach zwei Wochen war es wieder genauso schlimm. Die Prognose war nicht gut…
In meiner letzten Hoffnung habe ich K9 InuFlex bestellt. Seitdem er es bekommt, ist er viel beweglicher, kann sogar wieder rennen und hat keine Schmerzen mehr! Ich kann es jedem empfehlen, dessen Hund ähnliche Probleme hat. Vielen Dank!

I buy this product for my 17-year-old dog. I first tried it about 5-6 years ago, and back then it worked like a miracle. Within just a few days, my dog became noticeably more agile and “light on her feet.” At the time, I gave it as a course and then stopped.
At 17, the product can’t perform miracles anymore, but it has still made a big difference in her mobility and brought visible relief. She seems much more at ease now. So I’ve decided to keep giving it to her for the rest of her life.

Ho ritrovato il mio cane grazie a K9 InuFlex!
Da un po’ di tempo avevo notato che Bella, il mio pastore tedesco di 10 anni, si muoveva con sempre maggiore difficoltà. Preferiva riposarsi piuttosto che fare lunghe passeggiate, e persino la sua pallina preferita non la entusiasmava più come prima. Era straziante vedere come gli anni la stavano rallentando.
Una mia amica mi ha consigliato il K9 InuFlex e, sebbene fossi inizialmente un po’ scettica, ho deciso di provarlo – farei qualsiasi cosa per Bella. Dopo qualche settimana ho iniziato a vedere il cambiamento: al mattino mi aspettava saltellando vicino alla porta, e al parco correva di nuovo come faceva da giovane.
La cosa più bella è stata rivederla felice. Ho notato che si muoveva con più facilità e che tornava a godersi quelle cose che una volta le davano tanta gioia.
Consiglio vivamente il K9 InuFlex a tutti i proprietari che desiderano una vita più felice e senza dolori per il proprio cane. Sono grata per questo prodotto – Bella ha ritrovato la sua energia e io riempio il cuore di gioia ogni volta che la vedo giocare.
Lara, la padrona di Bella

Izdelek je neverjeten!
Moj 5-letni leonberžan se že od mladička bori z displazijo. Preizkusil sem že ogromno izdelkov, vendar nič ni zares pomagalo. Vedno je šepal.
Že pol leta jemlje InuFlex, in kot da bi ga zamenjali! Zdaj mu ga bom dajal vedno!

Wir haben zunächst mit K9 Fullflex begonnen, aber leider hat es nicht die erwarteten Ergebnisse geliefert. Also haben wir es durch K9 Inuflex ersetzt, das später auf den Markt kam und alles innerhalb einer Woche verändert hat. Mein vorher apathischer Beagle (damals 8 Jahre alt), der kaum noch laufen konnte, hat sich komplett verändert. Er war wieder der junge, energiegeladene, verspielte und glückliche Hund, der er früher war. Es sieht so aus, als müsste er dieses Pulver für den Rest seines Lebens nehmen. Hoffentlich gewöhnt sich sein Körper nicht zu sehr daran. Wenn ich Hilfe benötige, werde ich mich auf jeden Fall an Sie wenden.

Izvrstan proizvod!
Moj 9-godišnji pas jedva se ustajao i vrlo teško se kretao. Nakon nekoliko tjedana korištenja K9 InuFlexa primijetio sam veliko poboljšanje. Lakše se kreće, sada već i ide po stepenicama, i čini se mnogo sretnijim.
Preporučujem svima čiji psi pate od problema s zglobovima!

Après quelques jours d’utilisation, les symptômes des douleurs articulaires de notre chien ont considérablement diminué.
Le produit dure longtemps, et il est facile à mélanger avec la nourriture, qu’il mange volontiers.

Prodotto efficace! Probabilmente, senza questo prodotto, la nostra Gina, che ha 15 anni, non riuscirebbe nemmeno ad alzarsi in piedi. Anche salire le scale è diventato molto più facile da quando lo prende.

Toto dávam svojmu psovi, 8-ročnému nemeckému ovčiakovi, ktorý má bohužiaľ problémy s kĺbmi a medzistavcovou prietržou, ale s týmto práškom je jeho pohyb dokonalý, nemá žiadne bolesti a žije plnohodnotný život. Odteraz ho bude dostávať stále! Môžem len odporučiť!
