Are there any negative effects on coats by swimming a dog in a chlorinated pool?

Best advice I received on swimming a dog in your pool is:
Wet them down with a hose BEFORE you let they go for a swim....keeps the coat from absorbing as much chlorine as when they jump in dry...

...and rinse them with a hose afterward also.

Our dogs have been swimming in the pool for 25 years and I don't hose them off at all. They have never had a problem. However, if the coat is already dead and needs to be removed - it does turn browner faster on the blacks, from the chlorine

We put a pool in for the Labs 5 years ago, I couldn't keep up with the rinsing them off after business. They were in and out 8+ times a day. I just can't get all carried away about their coats--hoping they'll stay perfect for showing. They need to have fun too. I put the pool in so we all could enjoy it. And we do :)

This is something we tried

How about a salt water swimming pool? Does anyone have any experience with it?

my dogs swim every day in a great big salt water pool called the Atlantic Ocean and their coats are beautiful and clean..

MUST BE NICE!!!!!
Thanks!

My pool company told me that with the modern filtration systems it is not necessary to hose the dogs off.
