I had a poodle mix that did the same thing - and with the same foods - pizza crusts, pieces of toasted or hard bread, etc.
She would hide and save these "forever." I think somehow she knew that these would keep well - plus, for some reason, they never seemed to be anything she wanted to "eat right now."
I never thought of this as "gross." I'd find a piece of hidden dry bread once in a while - and it was just a piece of dry bread...... nothing bad!
And - she did this all her life...
So - for some dogs - this is very normal.
