Does wonders for my dog’s good stuff I recommend these products.* (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)
O2B K9+ very good productReview by Peter
Our Corgi is 13 years old and has joint problems..She could not walk up stairs or walk long distances, but after taking this supplement for a week she is walking a lot better, we have given her almost 300 tablets and no side affects.* We recommend this product. (Posted on 17/08/2015)
K9 PlusReview by Chrispy
Our 9 year old Golden Retriever has been diagnosed with the beginnings of arthritis . He had slowed down dramatically. Being allergic to beef we couldn't give him ordinary glucosamine. I found your wonderful product and he now has a bounce in his step, he's jumping up into the ute again without any effort. Amazing difference, we are thrilled to bits. Thanks so much for this wonderful product as it has given him a much better quality of life.* (Posted on 28/07/2015)
Working dogsReview by Kate
K9+ has boosted my 7 year old working dog (Hunterway bitch) who has not aged not very well and struggles to jump fences and get through a hard day at work, but since I've started giving her K9+; over the past six months her ability to work has improve immensely.

Her energy levels are up, she now plays with my puppy and her general well being and coat has increased quickly since taking it.
She’s a different dog all together.

I recommend K9+ to anyone with working dogs or pets looking for a more affordable option aside from vet products and that really works.

I have now started to give it to all my working dogs as they work very hard and need a boost to keep them in top health and condition every working day.*

We use this in our Vet PracticeReview by Maureen
Great feedback from my staff and customers alike. Using K9 Plus and Feline Plus regularly in our busy vet practice and very happy with results to-date. Good value for customers and certainly works well and is another well made natural product from O2B Healthy.* (Posted on 17/06/2015)

New lease on lifeReview by Val
I am so thankful for finding this natural product. My spaniel was going to put down, but after taking K9+ for only 2 weeks has got a new lease on life*... thank you so much.

RemarkableReview by Sheryl
While I was lying in bed at 6.30 one morning I was listening to Radio Hauraki and your ad come on for the dog supplement for arthritis in dogs. Right then and there I ordered some on my iphone, and it was delivered the next morning.

My 3 year old lab was diagnosed with chronic arthritis in all her joints when she was 3 months old and is on monthly injections as well as super expensive JD's mobility support food.

After taking your supplement for a couple of weeks the improvement in her is mind blowing. She is a completely different dog. Remarkable.*

Thank you so much for (firstly) advertising on Hauraki which brought your product to my attention, and (secondly) for having such an amazing product. I have recommended to heaps of people for their pets. (Posted on 17/06/2015)
