       Although it had a skull more like that of a big cat,‭ ‬Epicyon was an early ancestor to canines.‭ ‬Epicyon is noted for having an incredibly powerful body that may have weighed up to one hundred and seventy kilograms‭ (‬for Epicyon haydeni‭)‬.‭ ‬Its unusually shaped skull meant that Epicyon had a very short muzzle,‭ ‬something that may have enabled it to more easily crunch bones because the jaws biting down are nearer the fulcrum of the jaw resulting in more power.‭ ‬This advantage has also been proposed as part of the feeding method for Arctodus,‭ ‬better known as the short faced bear.
       While the exact methods of hunting and prey‭ ‬animals‭ ‬for Epicyon are not known with certainty,‭ ‬other later and powerfully built canids such as Canis dirus‭ (‬Dire Wolf‭) ‬are thought to have grown stronger so that they could tackle larger and more powerful prey.‭ ‬Given its muscular and heavy build Epicyon may have had a similar prey preference,‭ ‬as it would have been easier for it to chase and catch these types rather than smaller and faster prey.‭ ‬Epicyon might have also relied more upon scavenging than actual hunting.
