Dog got into baby formula can...

It’s a HUGE CAN, and it barely looks like any is missing out of it, if anything it just spilled but he may have ate some... not sure if it was from the can or just what spilled out. I am so tight on money currently and my dad kindly bought us some formula to hold us over until my next WIC checks and got us huge containers. I really don’t want to throw the container away, but I’m not sure if I should :( it’s a 35 dollar can so that’s so much to just toss!
