Narrative:

After loss of all fluid in right hydraulic system shortly after takeoff with me in control of the aircraft; I directed first officer to declare an emergency with ATC. We performed the abnormal checklist for the hydraulic system; climbed to FL70 and advised ATC of planning to dump fuel and return for landing. The fuel dump checklist was accomplished as well as the emergency landing checklist. Due to the normal difficulty with communication with this TRACON; the first officer was busy with the checklist while I was flying so I instructed the relief pilot to advise the flight attendants via the normal test information while at the same time; the relief pilot was contacting the company. After things settled down I made a PA to the passengers advising of the situation and to follow flight attendants instruction and that emergency vehicles would be present as a precaution. We returned to an uneventful landing. After gate arrival I was informed by several flight attendants that they were never instructed to perform their emergency landing checklist so that was not accomplished. I was under the impression that by giving the test briefing and time for the planned landing that this was their instructions to begin their emergency landing procedures;but apparently that was not the case.
