This question seems like a classic "List of X" problem, but it's scoped so strangely that the list could go on forever, or contain nothing at all.
The question seems to be asking for a list of animals, past and present, that could survive being attacked by a pack of war dogs. Which to my mind seems like an incredibly long list...
But it goes on to say that "Pack size is anything greater than 5 dogs." Which opens up an infinity problem... You could literally smother an entire world with near infinite dogs.
Beyond the obvious scope problem, this really feels more like a worldbuilding puzzle/golf problem than a legitimate question. I could be overthinking that bit, just a feeling.
Is this question really on topic? Seems like "too broad" might fit, but I didn't want to shoehorn it without some discussion.
