I never pickled hotdogs so that would be a question for somebody else. I only refrigerate my pickled eggs for 30 days till they are pickled then they go on the counter. I bought pickled eggs cheap from a bar in northern Wisconsin once on my way way home from Rhinelander. They were over a year old and none of his customers were eating them, I made an offer for the whole jar of eggs, he accepted, my brother and I had eggs to eat on the way home and he was out of the pickled egg business. In fact I still use that jar to make my pickles. The old eggs were fine. As long as the liquid covers the eggs you are good. Pickled fish went into the pantry after they were done but like my eggs they don't last long so I don't know about long term storage. Somebody keeps eating them. Mother in law was the pork hock eater and they sat on her counter but they never lasted long either. That might be a good question for the forum.
