Lisa and I took Sukoshi and Jolie to the Dog Beach. By chance we ended up at the very end of the beach and we were fine. But big dogs definitely out weigh the little guys. The large breeds were mostly labs and retreivers. We even saw a malamute swimming!
 
We only stayed about 30 minutes but we did enjoy our time there. 
Here are our links to threads with pictures from the Dog Beach.
