    I have a 10yr old Labrador with arthritis in one of her back legs. Definitely has made a great improvement to her mobility and pain. Would definitely recommend.

    After a lot of searching for an olive green collar (Not many companies do this colour) I ordered and it was delivered within 24 hours, complete with a packet of joint aid. Fantastic service and a great product. Amos already seems to be walking a bit easier.

    My older Jack Russell Holly has been wearing her Bio Flow collar for years. She is a very active sprightly 10 year old, so I thought that Charlie who is 5 might find one beneficial, as he too is very active and I would like him to stay that way.

    Purchased for my spaniel who’s only 5 but has arthritic joints in feet. Definitely not as lame as before the collar. Shame she can’t talk

    Oscar had been very lame, his left foreleg giving way and very painful, caused by damaging his neck running into a tree and knocking himself unconscious last April, his pain had become increasingly bad and he was started on Carprofen which helped enormously. As he is a young(ish) (7) dog the vets wanted to ideally get him off the drug and I decided to try a bioflow collar as it certainly would not make his condition worse. The change in Oscar is remarkable, it is like having a puppy again, he is full of life, happy, playful…absolutely worth every penny in our case.

    Bought the large size for my elderly German Shepherd dog. Within a few days he was up and about again and a few weeks later, I now have to take him out twice a night as he is full of beans! Thanks so much

    Bought this for my Springer Spaniel who had lost some of her spring. Our garden is up a steep flight of stairs and since having her Bioflow she no longer hesitates at the bottom before going up, and definitely finds it easier. I could see a marked improvement within a few days, would definitely recommend these for dogs great value for money.

    My arthritic shih tzu has been wearing this for 2 weeks after my vet suggested trying one. Have to say he seems a lot more settled and moving about a lot happier!

    Toby is an old dog of about 14 years who we got from the RSPCA just over 3 years ago. Earlier this year he developed arthritis in his front leg. Medication by itself had a certain degree of success but not nearly enough. Toby now wears his collar and is far more mobile. He has even started running about again – gently it must be admitted – but before the collar he could only walk for very short distances. Now his life is virtually back to normal. Very pleased and so is Toby

    We love bioflow products in our house. We have them for us where I really think they make a difference and for 3 of our elderly dogs. The collar has to be a fairly snug fit to work. Our papillon (long thick fur at the neck) has a cat collar. It has not made such an obvious difference to her as it has to the others. I certainly would advise these products to my friends. They are good quality and seem to work.

    My Weimeraner aged 11 has started limping and obviously his joints started to ache. After purchasing this Bioflow collar within 2 weeks it is hardly noticeable and he has a sparkle in his eye again. Thankyou

    Ordered collar on recommendation from my vet for my dogs arthritis and was very optimistic. Quality and size very good and fits perfect. We’ve had the collar on him since we purchased it a few weeks ago now. Sadly it doesn’t seem to have made any difference to his stiffness but glad I tried.
