It is in fact a group of rocks, made up of two needles (north and south). A summit block next to the north needle and a lower block below the south needle. These needles are built like a stack of compact boulders, which at first make for disconcerting climbing. But with a bit of practice, you'll enjoy it and come back for more.
The east faces are the most interesting. In the warmer months, it's nice there in the afternoon. The ridges face south. The Rocher du Chien has been completely refurbished as a "sports
site" by the CT FFME 58 in recent years. Several parts of the site lend themselves well to the installation of stoppers and this sector is suitable for initiation to trad climbing.
The foot of the routes is sometimes awkward with children, but the small river at the foot and the nearby undergrowth offer refreshing splashes and great walks for young and old alike.
