Bladder stones

Posted by Caro64 Caro64
Has anyone's dog experienced bladder stones whilst feeding BARF?
My 11 year old otherwise healthy terrier cross has just had major bladder surgery for removal of 2 bladder stones, one of which was lodged in his urethra and was extremely painful for him :( Thankfully he is now making a good recovery.
However the vet has said he should now be on a specialist urinary diet i.e. Royal Canin s/o which he won't eat. He's been fed a raw diet for a couple of years now but I am concerned it may have increased his chances of the stones. I am struggling to find info on the subject.
Would be very grateful for any opinions. I would preferably like to to tweak his raw diet to suit him and help prevent further stones.
