My dog can open the cabinet. We used thick rubber bands looped around the handle and onto the hinge of the next cabinet over. That worked for my lab unless someone forgot to hook the rubber band, which is often when you have kids. Then we got a Great Pyrenees, she just busts the rubber band. Currently we put a stool in front of the cabinet when we leave her alone (she doesn’t get in the trash when we are around) or just make sure the trash is empty. I’m considering getting some child proof safety latches but all I can find is plastic and she’ll likely just rip that apart too.
