I love golden retrievers, I have two of them
Nice, do you have hunting and shooting parties with them?
Definitely not, I just like to go to the park and let them chase each other
You must at least let them swim right? They have an instinctive love of water.
Only once in a while, but we should let them swim more often!
They're a long-coated breed, with a dense inner coat so dont be afraid to let them swim every now and then!
I will, I'm sure they'll like it!
Yup they need substantial outdoor exercise and swimming is the best kind of exercise. 
You're right!
I would suggest training them as a hunting dog!
