I have never personally had one but I think Golden retrievers are really good dogs! My best friend had 2!
I've had one, as well as Labrador Retrievers.  Both breeds really love water.
Do they? I didn't know that! What else are they good at?
Well, both were initially bred as gun dogs.  They were trained to retrieve shot game, often over water.
Oh wow thats crazy! Are they fast runners? Also how long do they live?
Well, they aren't super fast.  They love to roam though, so they need to be kept in a fenced yard.
Oh yes the adventurous pups. Are they good with kids?
Oh, they are simply amazing with kids.  They have the most even temperament of any breed I have encountered.
I agree, even though they were my friends dogs they got along with eachother and were the sweetest to me and all the other neighborhood kids too. 
I bet.  Because of how gently they are, they make great assistance animals, as well.
