I think you should feed the absolute best food possible to your Siberian Husky puppy, even if you have to give up a latte a week, or whatever! Especially now, when your puppy is growing rapidly and needs the best nutrition.
Here is a link to a website which rates all the dog foods: http://www.dogfoodanalysis.com/dog_food_reviews/
There should be little or NO grain in a dog's food! Most cheap dog foods are full of corn, soy, wheat and whatever else is cheap. Dogs cannot digest grains, and many grains cause severe allergies in dogs. The "meat" in cheap dog foods is usually filler and is not of high quality.
Please do not feed any dog the cheap store brand of dog food. Dogs might look like they are "OK", but they are not getting the proper nutrition. It is YOUR responsibility to do research until all your questions are answered and you are comfortable with what you are feeding your dog.
Siberian Huskies do not eat as much as other breeds. The Siberian Husky was developed by the Chukchi people in Siberia as a fast, lightweight sled dog that didn't eat much. My 9-year-old Siberian Husky only eats about 1 cup of high-quality food per day (she is moderately active). And, I won't feed her "senior" dog food because she doesn't need it.
There is a great internet group called "Sibernet" for people who are owned by Siberian Huskies. There are about 1100 of us from around the world. It's a great group of people and a valuable source of information and support Just do a Google search of "Sibernet" and you'll find how to join us.
