Matt101, I had a 5 month old pup with same injury last year and as northernlite and oddser have said, it's a badun. I saw 3 different vets and after x-rays etc they all said same thing, 4 - 6 weeks total kennel rest and only out garden on lead for toilet, and then the physio and gradual exercise etc, and then if everything went right he'd still probably not make an athlete ( their words) or working dog. Poor f***ker was going downhill mentally, not nice. And as bracken boy just said, there's a tremendous amount of pressure when twisting etc at speed on all the joints, ligaments etc. Anyway go
