Onions and Toxicity for dogs

Edgar's people cook most of his food for him, and add some good quality kibble to it, always being so careful in what they feed him (and their previous dogs). Several days ago she thawed some stew that she'd made them and thought she'd just give that to Edgar instead of making up a new batch of food. She knew there were some onions in it, but didn't think there were enough to be a problem.
 
To make a "long story short", Edgar got very sick.  Right now, he's very ill & in the hospital. He's had a blood transfusion yesterday. He's been in an emergency hospital in London,Canada over the weekend, but today I believe they are picking him up and taking him to their local vet for the rest of his treatment.
