Speaking generally -
Golden retrievers are great dogs and lots of fun to be around. From my experience (2) they are gentle, loyal and want to be one of the family.
We had a female and she was quite anxious but very intelligent, and a male who we still have. I think they prefer others of the same breed for company but get along okay with other dogs.
Our female had a couple of health problems (hips) and it was at this point we were glad we had pet insurance, as golden retrievers can be quite costly animals! Very rewarding though.
