Bruce is nearly nine months and has been on pro plan large breed robust puppy food as this is what he was on from his breeder . He is doing fine on this food he's in great condition and has no tummy problems . I was thinking of changing off pro plan just because I know the ingredients aren't the best but is it best to take a if it's not broke don't fix it approach ? I would hate to start stomach problems . The food I was thinking of changing to would be james wellbeloved but I'm confused as to whether he would need the junior food or just to go straight to adult and does he need large breed food ? This feeding malarkey is a minefield !
