High fibre dog food

[Vathek]

Please can you recommend a good quality high fibre dry dog food for my terrier and German Shepherd, both mature dogs. I have been using Tails.com but want to change as both dogs seem to have developed problems with their anal glands, so I think they must need a higher fibre dog food.

Thank you for your help.

You can use allaboutdogfood.co.uk to compare the brands. There is a filter for adjusting nutritional properties so you can add a high fibre filter.
