my dogs are raw fed,and i put my new pup straight on to raw food,as the breeder had her on bakers,and i didnt have any problems.If youre worried,you could gradually change over from your usual food,instead of making a straight swap,good luck.
My 3 week old pups are happily tucking into raw mince. My cats get raw chicken mince once a day, every day, always. My adult dogs get chicken carcasses every week, and my stud cats get chicken wings, all raw.
