Mainland Raccoon Dog (Nyctereutes procyonoides) lives in temperate forests across East Asia. It feeds on fruits and insects. Its conservation status is Least Concern.
Fascinating facts about the Mainland Raccoon Dog
- Only canids that hibernate, raccoon dogs bulk
In early winter they increase subcutaneous fat by 18-23% and internal fat by 3-5%, then their metabolism drops 25% while they sleep through the cold.
This fat-storage strategy lets them survive temperatures, showing how a predator can become a seasonal hibernator unlike any other dog or fox.
- Raccoon dogs swing dramatically in weight through the year, weighing just 3 kg in March and swelling to 6.5-7 kg by late summer, with some giants reaching 9-10 kg. This seasonal gain fuels their hibernation and reflects their flexible diet that shifts from insects and rodents in winter to fruits and amphibians in spring. The weight swing highlights their ability to store energy fast enough to survive harsh winters.
- Introduced for fur, raccoon dogs now blanket northern Europe: they are listed as an Invasive Alien Species of Union concern since 2019, meaning they cannot be imported or released anywhere in the EU. Populations are dense in Finland, Estonia, Latvia and Lithuania and have been reported as far west as Denmark, Norway and Sweden.
- Raccoon dogs may have been the missing link in the COVID-19 jump to people. Over a thousand were on sale at Wuhan's Huanan market, and swabs from a stall that housed them tested positive for both SARS-CoV-2 RNA and raccoon-dog genetic material. German virologist Christian Drosten called them the most likely intermediate host for both SARS-CoV-1 and SARS-CoV-2, underscoring how wildlife trade can seed pandemics.
- When faced with poisonous toads, raccoon dogs neutralize the danger by flooding their mouths with saliva, diluting the toxic skin secretions enough to swallow them safely.
