This ancient German breed is very popular as a market goose throughout Europe. In Europe it is found in Grey and White but the most popular and common form is Saddleback. In the US only the Saddleback varieties are common, in both Buff and Grey. The beak, legs and feet should be a deep pinkish-red and the paunch is single-lobed. These geese are good layers, producing 60-80 eggs in a season. Ganders weigh 17 to 18 pounds and geese about 15.

In Europe, Buff Backs are not considered the same as the Pomeranian, but rather is a term to describe the coloring of any saddlebacked breed.

Pomeranian Goose

Pomeranian geese average 15-17 pounds and lay 15-35 eggs annually. Northern German farmers developed the Pomeranian goose. Literature references date its origins to as early as 1550. The Pomeranian is the only descendent of the European Greylag specifically bred for a single-lobed paunch (Ashton, 1999). In North America, however, Pomeranian geese often exhibit two lobes due to crossbreeding and genetic variations.
