First thing, my eight-year old Boxer lady, Ruby, absolutely loves the starter pack, absolutely gobbles it down. Secondly, I must have rushed into the program too quickly as the change in food wraught havoc with her intestines. No poo for three days and beginning to panic. Just before a necessary vet visit I switched her diet back to her original diet. Hurrah! Poo, never been so glad, took a photo and sent it to the wife. Lesson learnt. Now diet is : morning 50g dog meal + 125 g Naturaw raw meat, evening 60g dog meal + 150g Naturaw raw meat. Ruby still wolfes this mixture down. Will continue with this plan until I am advised otherwise.
