Alfie had to have his anal glands emptied last year before he was 1 which I thought was quite young fo him to start needing that done. I tried weetabix initially as suggested on COL then went onto oat bran from a further post. I sprinkled a dessert spoonful onto his tea each night. A further recommendation here was to change over to the Arden Grange food, as then he might not need any added bran. I changed Alfie over to the AG food and his glands have been fine since, though it very much seems to depend on individual dogs what works best for him/her. It was also suggested that dogs are more prone to being intolerant to wheat rather than oat bran.
