It is a relatively small warehouse in an ultra-high trans-lunar orbit, mainly servicing eccentric Moon-L2 routes as well as potential routes to interplanetary destinations. Currently the only interplanetary destinations in existence are small research outposts orbiting Mars and Venus, but there's a marginal market for speculation on future interplanetary development that keeps Dogtooth operating.
Dogtooth has a fairly common layout for a high-space cargo depot. It consists of the "wet hold", a massive spindly steel superstructure used to hold cargo containers, as well as a "dry hold" cargo bay, a smaller pressurized warehouse used for storing any goods which might be damaged in the vacuum of space. Attached to the cargo bay is a small crew habitat which houses the permanent on-site staff.
Everyday station functions are mostly automatic, but a 4-man skeleton crew are stationed permanently on-site to handle maintenance of the logistics machinery. This is a minimum operating requirement to remain insurable.
