       Although not a very well-known amphicyonid,‭ ‬Drassonax does help to reinforce the image of the earlier bear dogs being very small predators that were second to creodont mammals like Hyaenodon during the Oligocene.‭ ‬Ultimately however the creodonts did not adapt to changing climatic conditions which drove the development of new prey types,‭ ‬and with the arrival of newer larger bear dog forms such as Amphicyon,‭ ‬the bear dogs took over from the creodonts.‭
       Because of its small size,‭ ‬Drassonax would have been a hunter of other small animals as well as possibly a scavenger that fed upon the leftovers from the larger predators.‭ ‬These larger predators included the aforementioned creodonts as well as false sabre-toothed cats.‭ ‬Both of these types of predators would have been easily capable of killing a small amphicyonid like Drassonax.
