Golden Retrievers are very polite dogs. In-laws had one, and she was so docile that I thought there was something wrong with her.
It depends a bit on the particular dog, as with most breeds.
I had a male Golden (papers) from a shelter. He was a very loving dog, great around kids and even cats, but had a dominance problem with other dogs. And he was hyper—needed a lot of exercise. I couldn’t imagine him waiting in line like those nice doggies.
My parents have owned goldens for about 50 years. In my experience, the females are sweet and very polite. The males are sweet but extremely rambunctuous.
