Red foxes dominate raccoon dogs, sometimes killing their kits or biting adults to death. Cases are known of red foxes killing raccoon dogs after entering their dens. Both species compete for mouse-like prey. This competition reaches a peak during early spring when food is scarce. In Tartaria, red fox predation accounted for 11.1% of deaths among 54 raccoon dogs and amounted to 14.3% of 186 raccoon dog deaths in northwestern Russia.
