Do golden retrievers have any health concerns?

I hear that golden retrievers are possibly susceptible to Hip Dysplasia especially if you got the dog who came from one of those infamous puppy mills/factories.

The more popular the breed the more puppy mills try to knock out as many pups as possible. Bad breeding practices lead to higher rates of genetic diseases.

Here's a link to the basic genetic diseases that are often associated with the breed:
