Friends, I'm new here, but I have done some digging into this topic, and believe it or not, I don't find these accounts to be plausible. But I'm going to explain why.
Believe it or not, none of these accounts have been scientifically verified, so one must take caution if they are to believe the accounts.
The stories describe many dholes being killed by the tiger before the others finish it off, I do not find this plausible since when the size of a pack is reduced, that means hunting will be less efficient, there will be fewer members to raise the pups, and they will be more vulnerable to being overpowered by a larger pack. So hunting tigers is going to be a huge risk, and an unnecessary risk at that. Animals will not take unnecessary risks simply because that would be stupid. Also, there hasn't been a single case of dholes chasing off or killing a tiger for several years, and it is no longer believed that dholes supress tiger populations since many places that have dholes have seen an increase in the tiger population, something that wouldn't happen if dholes contained tiger populations.
