I have one doggy and he's a golden retriever.They were bred to retrieve fowl from the water during hunting. 
Aren't golden retrievers really smart?
Yes they are! They also instinctively love the water and are easy to train!
Are they a good family dog and safe to be around children?
Absolutely, they have a friendly and gentle temperament and they are the third most popular family dog breed in the US.
How long does a retriever usually live?
You know I'm really not sure but they are well suited to live in country and suburban environments.
In what part of the world did retrievers originate from?
