Have you thought of making your own topping for the dry food.Rosie has dry kibble but once a week I buy turkey mince or cheap white fish, chop up carrots , sweetpotato, butternut squash broccoli peas...in fact what ever veg I have....cook veg in a little water, add meat/ fish..cook ..then freeze in tubs along with the cooking juices.Just defrost and heat up enough to go on Her kibble along with some of the juice to make a gravy.....so the kibble soaks up some of the juice.....takes no time at all.Occasionally we use bought wet food just to ring the changes.And its cheap..probably under £ 5 for enough for a week and we use less kibble.(Not sure I would want to do it if I had a few dogs though.)Means Rosie have a variation of diet.
