For the next three and one-half months, "Sea Dog" operated out of Subic Bay and, on 12 January 1946, set a course for the West Coast, arriving at San Francisco, California, on 2 February. Overhaul at Mare Island followed; and, in June, she returned to Pearl Harbor to prepare for her second postwar deployment to the Far East. During July, while en route to the Philippines, she conducted a mock war patrol. In August and early September, she provided antisubmarine training services to Seventh Fleet units in the Tsingtao area; and, at the end of the latter month, she returned to Pearl Harbor.
