GSD female low on weight

Question
I am having 11 mths female GSD. She weighs only 23kg. I feed her Royal canin food. She is very active all the areas. But weight is not up to the mark. She wil not eat unless I feed it manualy also along with biscuits. Other wise she will not eat for full day. Eating habit is not regular. I give other multivitamin tablet, deworming medicine as per pet doctor advice. Any suggesstion please. I am from India

Answer
Many young Shepherds are like that.  The manual from the dog guide school gives this, ''Note: German Shepherd puppies typically will look very thin throughout puppyhood.''  I would keep feeding her what she eats, except skip the vitamins.  The Royal Canin should have all she needs. Too many vitamins aren't good for a dog.
