Puppies are gangly and skinny while growing. Feed her more. Her body is using it and needs more. Give her a bigger helping at each feeding. Definately get her off of the Purina food. Purina anything doesnt have any nutritional value to it at all. It basically fills the tummy so the dog doesnt go hungery
I tried to feed Blue Buffalo.. My dogs hated it. They only ate it because they were hungry. Your dog may react differently. However; I have come accross a supreme food that provide all the right stuff your pup needs.... Innova. Innova carries an "alternative to the raw diet" formula. Its called Evo. I fed my Pit Bull that while she was growing. She was getting skinny on the food I had everyone one, which was Natural Balance. I switched her to the Evo and she bulked up real nice. I fed the Red Meat formula, but they have a chicken formula as well. Once she turned a year, I put her on Innovas maintenance forumla. With this brand, it can be used as an all stages type of food. So you can put your 9 mo on the Evo without the dog missing out on any of the needed nutrients for growing.
I really like Innova. My dogs love to eat it and it really does make them look nice. I will recommend Innova to anyone who will ask. I think this brand of food really outweighs everything else. It really is worth the price.
Here's Innova's website. Listed is both Innova, Evo and the other brands of food that Natura Pet Foods makes.

I really like this website also. It grades the foods on what is top notch and what is bottom of the barrel and its not based on personal opinion.
