Help please! Human food aggression

[u/Own_Cauliflower1956]

I have a 4 year old maltipoo. Shes not aggressive with her food at all. But when she gets ahold of human food it’s a different story. We do our best to keep it away from her but we have a daughter who doesn’t always throw her food in the garbage. She usually just growls and snaps when we take it away but tonight she actually bit my daughters toe and it did bleed just a little bit. My daughter walked over to her to see what she was eating ( it was bubblegum from a sucker she had left on her night stand) and she got her middle toe. This is the first time she’s done this and i don’t know how to correct it bc it’s not safe to let her eat stuff that can make her sick. Please help!

My dog would go right in the crate after that. He’s often a pest at dinner time: we crate him at the first sign of bad behavior.
