The farm of Dalland is located in Mosfellsbær, only about 15 km from Reykjavík, the capital of Iceland. Gunnar B. Dungal and his wife Þórdís Alda Sigurðardóttir have been breeding horses there since 1977. They started on a small scale, with one or two foals per year, while today (2013) about fifteen to eighteen foals are born each year. The first mares they bought for breeding were Lýsa from Efri-Rotum, Eyjafjöllum, in South Iceland, and Vaka from Dýrfinnustaðir in Skagafjörður, North Iceland. Many of the Dalland breeding mares are descended from these first two mares. Then they bought the mares Gróska, from Sveinn Guðmundsson of Sauðárkrókur, Skagafjörður and Von from Kristinn Guðnason Skarð,Rangárvallasýsla as foals, and later Rjóð from Syðra-Skörðugil, Skagafjörður and Katarína from Kirkjubær, Rangárvallasýsla. Other mares whose descendants have contributed to the breeding are: Hátíð from Dalland, a daughter of Sýsla from Dallandi.

In 2013 there are 25 first prizes mares and stallions which have been born and brought up in Dalland. Also there were 4 mares bought as foals and 3 years old Lýsa,Von,Katarina and Una and all four got1st prize in breeding shows.

Dúkkulísa from Dalland was awarded an honorary prize for offspring at the Icelandic National Horse Show (Landsmót) in 2006.

Emphasis has always been placed upon using outstanding stallions, chosen specifically for each mare with respect to gait talents, build and character.

Dalland and the adjacent estate of Búrfellsland, which also belongs to the farm, comprise a total area of 400 hectares, where extensive afforestation has been carried out in recent years. Tens of thousands of trees of various species have been planted, both for shelter and for their aesthetic value.

The estate includes varied land, from hillsides and tussocky marshland to grassy pastures surrounded by trees, which provide good shelter for the horses. The farm is ideal both for young horses which need freedom and exercise, and for horses in training, which are easily accessible in paddocks near the stables.

Untamed horses and the breeding mares are now (2013) kept on another farm, Héraðsdalur l in the northern Iceland. The two farms Héraðsdalur l and Stapi in Skagafjörður are also owned by Gunnar and Thordis. In bad weather there are shelters so that all the animals can stay under roof if they want.

The farm’s policy is to apply the following procedure: breeding, raising, training, after which a decision is made on the future of the horse.
