Ben Mitchell, Crewman at Sunderland Lifeboat said:
"There was a lot of risk involved in the majority of our options which would put our crewman in danger.
"One particularly large wave seemed to pick up the dog and wash it further towards the promenade, at this point we became increasingly concerned as the waves seemed more violent in that location.
"However, the two coastguard officers on the promenade were able to then coax the dog to swim towards them and effect an excellent rescue of the dog up onto the safety of the promenade."
