Basic Browns are introduced in the beginning of How to Train Your Dragon and seen throughout the Book series.
- "The Common or Garden and the Basic Brown are so similar that they can be dealt with together. These are the most familiar breeds - the ones we instantly think of when we say 'dragons'. They are poor hunters, but they are easy to train. These dragons are the best kind for family pets, although, as with a lion or tiger, they should never be left unsupervised with very young children."

Basic Browns are, as the name suggests, basic and brown. Basic Browns are brown and slightly larger than the Common or Garden Dragons.
Basic Browns have no specialized abilities, and are average in hunting, flying, and fire-breathing. One interesting trait, though, is some individuals can be almost completely vegetarian, which is unusual when dragons are almost strict carnivores.
In the first Book, the young Viking must catch their first Hunting Dragons from the Dragon Caves during winter, when most dragons hibernate. Hiccup grabs a Basic Brown, but upon seeing Fishlegs did not get a dragon, Hiccup gives him this basic brown. Hiccup grabs another dragon, which later turns out to be Toothless. Fishleg's basic brown is named Horrorcow, and is almost exclusively a vegetarian. She is a poor hunter, but very good-natured.
