When did the Amphicyon go extinct?

Why did Bear dogs go extinct?
They were among the first carnivorans to evolve large body size. Later in their history, they came into competition with hesperocyonine and borophagine canids. As dogs evolved similar body sizes and cranial and dental adaptations, the rise of these groups may have led to their extinction.
Why did Amphicyonidae go extinct?
Amphicyonidae is an extinct family of terrestrial carnivorans belonging to the suborder Caniformia. As dogs evolved similar body sizes and cranial and dental adaptations, the rise of these groups may have led to their extinction.
Can a bear breed with a dog?

Could amphicyons have denied a hyaeonodon its recently killed prey?
One can imagine a pack of hungry Amphicyons denying a Hyaeonodon its recently killed prey, thus leading, over thousands and millions of years, to the eventual extinction of this otherwise well-adapted predator. Strauss, Bob. “Facts of the Pre-Historic Predator Hyaenodon.”
