This isn’t super surprising. Owners of big dogs generally know that their dogs are a problem, so they keep them somewhere that they can’t attack posties, and also are more likely to train the dog not to attack. Small dog owners are much more likely to be careless because aggression from them is seen as cute or funny. So they don’t get training, and don’t get put behind a separate fence.
I have had big dogs and little dogs in tandem for decades. Big dogs tend to be far more mellow. Little dogs have no chill. I have never had a problem with a big dog. They all (except one) seemed to default to couch potato mode. My wife’s little dog though… Careless or careful makes no difference.
