Made a differenceReview by Julie N
This has really helped my Jack Russel with his movement!* (Posted on 16/05/2017)
A brand new dog!Review by Susan
Our poodle bichon x had itching and joint pain but with K9+ is now a new dog! Happy with no paw licking or itching. (Posted on 12/04/2017)
What a difference it has made! Review by Gina
I just wanted to say what a wonderful product this is. We had two dogs on the k9 plus pills and what a difference it has made to their lives. The dogs function so much better since they have been taking these pills. If we go for a walk, I double up their dosage and they are completely fine. Off the pills one dog starts to get a sore leg and the other a sore back. These pills are magic.* Luckily for us, both dogs eat them out of our hands. Thanks for making a great product. I am always recommending it to my friends if their dogs are suffering.

Given the all clear! Review by Sharon
We used this as main rehab tablet for our German shepherd after his ulna osteotomy. He has recently had his 6 mth post op X-ray and we got the all clear! He also takes a combination of O2B Fish Oil and Glucosamine Powder* (Posted on 9/03/2017)
Keeping agility dogs in top notch conditionReview by Agile Agility Dogs
I have 2 border collies who compete in agility.
Riot had a nasty accident prior to starting her agility career back in 2013. Along with other alternative treatments such as acupuncture, K9+ helps to keep her playing her agility game.
I notice a difference in the days between doses if I run out, she becomes a little bit stiffer and not as able to keep up with the others.
The days prior to and over a show weekend I also use K9 Octane, and I have really noticed a difference in her performance, especially on day 2 of a show where she use to slow down a bit, she is now performing as well on day 2 as on day 1.

Hype is 20 months old and has just started her agility career, she has been on K9+ since I got her as a puppy.

As active dogs who are asked to perform all sorts of tight turns and obstacles at speed its really important that I am able to help support their joints for years to come to be able to keep them fit and happy.
It took me a while to find a product that I trusted and found actually worked, but since finding k9+ and K9 Octane I could not be happier, and neither could my girls!

Thanks O2B healthy for producing such a great product!* (Posted on 9/03/2017)
I can't rave about you guys enough!Review by Cherie
Got about a weeks worth of sample packs from my mum while at the dog show in Nelson recently and I can't rave about you guys enough! Our nearly 10 year old huntaway X cattle dog has been very stiff in her hips and back legs lately. After a week she was so different! More energy, shinier coat and now running around and not pulling up lame when hubby takes her out for a run with the motorbike. We are definitely going to buy more of these to keep her happy and healthy. Thank you so much for making such an incredible product! And Krista thanks you too :) (Posted on 16/02/2017)
She's had great mobilityReview by Candy
My Wheaten Terrier has been on 3 per day for most of her 9 years after a serious knee ligament operation. Prognosis for the other knee wasn't good. So far we've avoided another operation/vet fees and she's had great mobility.* (Posted on 7/02/2017)
Amazing product K9+Review by Jackie
My miniature schnauzer was suffering extreme pain with arthritis in her lower back. She was unable to jump and some days barely able to walk. After two weeks on this product there was significant improvement and now having taken K9+ for three months she is back to her old self - running, jumping, very happy. There is no sign of pain at all. This is an amazing product.* (Posted on 27/01/2017)
Ready to go the next day after a hard day's run!Review by Justin
I really thought they worked well on my dogs, old and young ones... coats were shiny seemed to keep weight on them as well. I noticed they were ready to go the next day after a hard day; muscles and joints weren’t as stiff. A good feed of K9+ & K9 Octane just keeps them rearing to go... love the organic natural ingredients keep up the good work.* (Posted on 7/12/2016)

Amazing results!Review by Jenny, Nelson
I've had absolutely amazing results for my 10 year old miniature dachsie, 'Lolly', who was not able to move around much. Now, you can't keep her down!*

I can't recommend this product enough, thank you! (Posted on 26/09/2016)
Highly RecommendedReview by Julie
Since using the O2B K9+, my Cavalier King Charles has a whole new quality of life. I highly recommend this product to all dog lovers! (Posted on 22/09/2016)
The change has been incredibleReview by Sherrie
Our almost 12 year old GWP gundog is now bouncing around like a puppy again.

It is most obvious she is much more fluid and before I can pick her up she has jumped into the back of the 4WD.

The formula along with the fish oil capsules has also made her eyes brighter and her coat is now a deep chocolate liver colour. It looks like we will get a couple more years out of the old girl yet.* (Posted on 22/09/2016)
Brilliant productReview by Lou
I have been using K9 Plus for a working heading dog of mine who had a bad leg injury (broken tendons etc). I believe the tablets really helped with the recovery process and has made a huge difference to his mobility. With his injury I was basically looking at having to retire him, but with the help of K9 Plus he continues to be a valuable working dog.

After this experience I now give K9 Plus to my older working dogs on a daily basis - within a week there is a noticeable difference in their energy levels and mobility. I recommended this product to my parents who have a 13yr old corgi who was struggling with the onsets of arthritis. She is now a whole lot more active and comfortable, K9 Plus has worked wonders for her.*

Thank you for a such a great product, I am constantly recommending it to other people who have dogs that are getting on a bit in age or just need a bit of a boost in general. The other great thing is that the dogs love it - mine line up in the morning waiting for their tablets and eat them straight out of my hand!! (Posted on 18/08/2016)
He's like a 7 year old again..Review by Vivienne
K9 Plus has taken years off my 15 year old lab, Dusty's life. He is full of bounce, energetic and the picture of life after having a hard downhill spell with sore joints seizing up his legs and neck. He's like a 7 year old!

He just picked up the tennis ball for the first time in 6 months and tossed it around the room playing with it. Lovely to watch.* (Posted on 29/06/2016)
16 going strongReview by Rob
Got this for my 16yo staffie x who lately has been looking really old. She has had a few knee ops and with her age has just been starting to seize up. She seemed to be in a bit of discomfort and wandering around constantly to ease the aches. So far it's been a week on 2 pills a day and she's gone mad. She has gone from waddling around slowly to madly galloping around the place. She seems to be moving a lot easier and when she lays down she doesn't keep getting up again out of discomfort.* So far so good. (Posted on 13/06/2016)
Awesome product.Review by Lou
We have an 8 year old Great Dane called Baz. He has got arthritis in his back left leg. Limping round not being able to put any weight on his back leg. He just wasn't his happy self anymore. Since we started him on k9+ he doesn't limp anymore and is happy as.* We give him 4 pills a day as he's 76kg and we are just over the moon with results. (Posted on 29/04/2016)
A 9 year old Golden Retriever with the start of hip dysplasia Review by Chris
We have a 9 year old Golden Retriever with the start of hip dysplasia in his right hip. He was beginning to limp occasionally and was reluctant to jump into our vehicle. As he is allergic to beef we tried the K9 Plus and he hasn't looked back. He has much more energy, happy to jump and is back to his normal toy fetching self. We are very grateful as he has a much better quality of life because of your product.* Thank you.

A much happier dogReview by Claire
Turk (GSD) competes in obedience and was doing crooked sits, he couldn't jump over small fences but after being on K9 plus & Omega 3 he can now do straight sits and jump over small fences*, he seems like a much happier dog. (Posted on 25/01/2016)
BrilliantReview by Spider
I give these to my darling, energetic but getting noticeable older 13 year old girl, and if we run out I really notice the difference in her general well-being and mobility. (Posted on 7/09/2015)
