I'm feeding a combo of Orijen and raw for my dogs. I just didn't suggest the Orijen because I'm in America so I'm not sure what brands you have available to you. Sometimes taste can be a choice. I've had all kinds over the years, some didn't care if it was food or trash as long as it was edible while other had a particular brand they enjoyed. For general info about different brands Dog Food Reviews and Ratings | Dog Food Advisor
is a good place to go.
How is her stool? I was wondering how much liver she gets in her other meal because I know for a fact too much liver can cause runny stool and an upset stomach which can make a puppy less likely to eat as much.
