It sounds to me like you are doing everything right, just keep up the good work!
I also once had a Golden Retriever and a Yorkie.....they were just like night and day in terms of potty training. I raised the Golden at the same time as my human baby and we decided that the Golden had an IQ of about a 3 year old child, which is a lot of intelligence if you really think about it! (After that point, my daughter understood words and commands that the dog did not.) Our Yorkie still had accidents until he was over a year old, but at least they were Yorkie sized accidents! The Golden accidents were monumental!
Best of luck to you...........
