How do you keep flake food as flakes?

I bought some new flakes yesterday, they are called TetraFin Goldfish flakes and now I shake the can so the flakes land in my palm and when I have enough, I pour it into the tank. BTW I used the old fish flkes for my goldfish fry.

P.S. Yesterday night, my dog slept with me and I had the ground up fry food on my desk and sometime in the night, she ate the whole darn thing. So now I have to grind up the new flakes on my own now.
