Poaching is a multi-million pound industry, run by international criminal networks who trade in ivory, the material elephants' tusks are made of.
As a result, nearly a third of Africa's elephants have gone in seven years, and experts say they need protecting now more than ever.
Conservationists are fighting back using specially trained dogs. They are deployed with their handlers by helicopter, and if the poachers are still in the area they can be immediately stopped.
The dogs are being trained in skydiving too because this method is fastest.
In the long term, it's hoped the successful protection of elephants will see Africa's population rise again.
Watch the dogs in training here.
