Your quote that he would consider you food simply because of his size is nonsense.
The point is whether they show aggression and how they pursue it. Many dogs will “doggedly” attack tenaciously, as in, not letting it go. That includes little dogs, who show the same propensity as large dogs for the same aggression and “doggedness”. They do not seem to be dissuaded by size.
If cats were so inclined they would also regularly be caught charging and hanging onto humans, not letting the issue drop. I have never heard of such a thing, although the evil cat I did have could come close. I was fearing she was one day so got rid of her, to the pound (would not have good conscience passing her off to anyone). But other than she, I’ve never experienced it nor even heard of it.
Meanwhile, headlines for dogs abound, and I’ve seen it plenty in little dogs, too.
We don’t agree, but have a great day.
Cheers
