Depends on the dog, depends on the child. As per the paper, breed is a poor predictor of behaviour. I wouldn't let most adults in this thread play with my dogs unsupervised, based on the state of the comments.

Talking about non-outliers as if they have better knowledge of what the safety hazards are is a fallacy.
