Abstract
A latching dog includes a dog body, at least one engagement arm protrudes from an outer radial surface of the dog body in a transverse direction, and at least one retention fin protrudes from the dog body in a longitudinal direction. The at least one retention fin maintains the latching dog engaged with a housing surface to keep the latching dog at a desired axial and/or rotational position while milling the housing and latching dog.
