There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
The dog and dhole don't belong to the same species or even the same genus, so I don't think they gonna breed in the wild.
BTW, the tiger and leopard are notoriously known as the "dog killers", so they might be effective to control the population of the feral dogs that return to the wild.
As long as the tiger and leopard have a sufficient number, then this new structure for the ecosystem might work.
