Food for pregnant bitches

There is currently one recipe available for puppies/pregnant/lactating bitches, if I’m not mistaken? Should this recipe be adjusted depending on the stage of pregnancy the bitch is at? Which brands of iron and zinc can be used? That are easy to get hold of, e.g. at a chemist’s or health food shop..

• The recipe can be adjusted according to the bitch’s weight, but it does not need to be adjusted based on how far along she is in her pregnancy. You can buy Nycoplus Zinc (13mg) or Nycoplus Iron (20mg) at the chemist’s 😊
