Status of the species in Latvia: A comparatively evenly distributed and common species in the entire territory of Latvia. According to the data of the Central Statistical Bureau for 2019, the population of raccoon dogs in Latvia reaches approximately 27,700 individuals.

Where do they live? Raccoon dogs mainly occur in moist mixed and deciduous forests near swamps, lakes or rivers, in the coastal areas of different water bodies, shrub-covered alluvial meadows, grass marshlands and borders of other marshy areas. They select abandoned badger or fox burrows as their winter dwellings, as well as they dig their own burrows or use natural hiding places.

How do they live? The smallest canine of Latvia is not only a loving and faithful partner to their mate, but also to their inhabited territory. Raccoon dogs choose their partners for life and do almost everything together – seek food, walk, rest, raise their offspring and even overwinter! Raccoon dogs are the only canines that hibernate in winter. They spend the cold winter months, most commonly - from November to March, in an inactive state, which can be described as partial hibernation. During this period they feed on the accumulated fat reserves. However, when the snow melts, on warm days, they may wake up and go in search of food. Probably, their hibernation can be explained by the low height of the raccoon dogs and short legs, which make mobility and the search for food (hunting) inconvenient in winter with deep snow. 

What do they eat? Although categorised as predators, these animals are proper omnivores and their menu changes depending on the season. Most of their menu consists of mice-like rodents, insects, amphibians, birds nesting on the ground, eggs, fruit and berries. They are also fond of agricultural crops like oats, corn, pumpkins and other greens.
