We use the Local Group satellite galaxies as probes of dwarf galaxy formation processes within the framework of the hierarchical structure formation theory. As the Local Group dwarf galaxies are not unambiguously verified to be dark matter dominated, their three-dimensional and global kinematic properties are a part of the evidence to discriminate two building mechanisms of dwarf galaxies described above: cosmological building blocks or tidal dwarf galaxies? The spatial and orbital properties of the satellite galaxies of the Milky Way and Andromeda are studied. Statistics are developed to compare these distributions with random distributions expected from CDM simulations. Internal properties like mass-to-light ratia of model galaxies, initially set up to resemble tidal dwarf galaxies that orbit in the gravitational potential of a host galaxy, are analysed.
