Flexx mobility and joint supplement

Brody my yellow lab has severe arthritis and has recently been through cruciate surgery and a second surgery and is still struggling with his hind leg . To aid his recovery I started using Flexx to help support his recovery , help the healing of all the muscles joints tendons etc in his legs , assist with helping move the joint and his arthritis and try to help him feel more comfortable . It showed its results quickly in a change in brodys behaviour . He was happier , more comfortable and wanted to play and chase about plus the joint moved easier . Coincidence maybe but I 100% believe the flexx has made a huge difference for him and its now assisting his recovery from his recent op . I'll definatly continue brody on this for life . Thankyou f&j for all your help and support xx

Perfect supplement!

I bought this for my dog Darcie as she trains in agility and I wanted to support her joints as she is so active. I also thought it would be good to support her after such a long break from training due to Covid. Well I haven't been disappointed! She is loving being back at training and I love knowing that her joints are supported while she does what she loves. Thanks so much!
