Merlin (beagle)

Merlin is the pet prize beagle owned by Captain Jaryd Harker, MD, USS TwilightNCC-74413. The captain's beagle is a common sight in all areas of the Twilight, most especially the captain's private cabin, the Captain's Ready Room, arboretum, and the holodecks. Bold and friendly, the beagle is known to park himself on couches, beds, and once, the captain's chair on the bridge.

("Sir? I think Merlin outranks you.")  The captain turns and sees the beagle sitting in his chair. He sighs. "Merlin, get down!" (The dog doesn't budge. He sighs again, picks the dog up, sits down, and puts him on his lap.)
