Lily, a Siberian mix, and Moira, a Border Collie mix, won't touch anything unless I tell them to 'Get it'. Even meat dropped on the floor is safe. That applies if I am anywhere in the house. All bets are off with Lily if I leave the house. Raw food thawing for their dinner - at least she had the courtesy to serve Moira. There was an empty plastic on each bed. Stick of butter. A loaf of thawing bread dough. That initiated a phone call to the emergency vet. I had to make her vomit before it raised in her stomach - he said it would be fatal. Hint - if you have give a dog hydrogen peroxide, do it outside. While on walks, Moira looks for bread people put out for the squirrels which is bad because she gets ear infections if she get a smidgeon of bread with yeast.
So, I have two answers - yes, I trust my dogs if I'm in the house and no if I'm not.
