This is Sethi, he is a Gordon Setter who has weak cruciates and a bulging disk in his spine.
His owner Sue had the choice of having both of his back legs and spine operated on or wait and see how he got on.
She was unsure before putting him on Mobile Bones but thought it was worth a go. After a year I stopped feeding Mobile Bones and he became gradually stiffer over a period of 2 - 3 weeks. Within a week of putting him back on it he was a much happier and obviously had less stiffness.
