I have a golden retriever! I think they're the most friendly, gentle dogs!
Oh my friend has a golden.  Very sweet dog!  Are they smart dogs?
Very smart! They're a very popular breed that's used as disability assistance dogs for the deaf and blind.
My setter/corgi would knock over a blind person, I'm afraid.  It's good there are dogs who can work with people with disabilities.
I agree! The only thing you wouldn't want a golden retriever for would be as a guard dog. They are unsuited for that job due to their sweet, gentle temperaments! 
Ha ha!  I guess that means goldens are good with kids, too.  My kid climbs my dog all the time.
They are fantastic family dogs! They're actually the third most popular breed for families in the US! My dog is great with my kids!
