Golden Retrievers are one of my favorite dogs!
I know they are a large sized breed of dog.
yes they are! They were first bred in the 19th century in Scotland. 
They were named retriever because of their hunting ability to retreieve already shot animals.
Yes they were very popular with the british for that reason 
Yes, they have such a long coat and dense inner coat that keeps them warm.
Yep! They have a life span of 10-12 years. which is great! Maltese has the highest lifespan of 12-15 years.
They need alot of outdoor exercise, because of their tendancy to roam around.
Yes i agree completely. They need an environment fit for them! Large yard, Lots of walks and action!
