Five weeks ago, a 1-year-old German shepherd-husky mix with startling blue eyes fell off a fishing boat in the Pacific Ocean north of San Diego. The dog, named Luna, was miles from land.

She was reported missing on Feb. 10 by her owner, fisherman Nick Haworth, who told authorities that Luna was a strong swimmer and would head toward land. But the nearest shoreline was San Clemente Island, home to a U.S. naval facility and about 2 miles from where the dog fell into the water.

Sandy DeMunnik, public affairs officer for the base, said staff helped Haworth search the island for the dog, but with no luck.

"He stayed in the area for two more days to look for her, and after a week, we considered her lost at sea and presumed dead," DeMunnik said, according to ABC News.

Crushed, Haworth made peace with Luna's death, posting on Facebook, "RIP Luna, you will be greatly missed."
