We have a new whippet puppy that has been feed on a raw diet (chicken mince and bone) since weaning (Chicken Mince with Bone - theyloveit.co.uk). I took him to the vets for his first jabs yesterday and it was suggested that he may not be getting all the vitamins and minerals he needs from this raw diet and that it would be better to move him to a 'complete' dry diet. So now I'm very concerned, what should I do for the best? If I do decide to move him to a dry diet how is it best to transition?
