What is the best way to keep water out of my ears while swimming freestyle? - freestyle swimming pants

I'm holding a giant mammal with big ears and it is obviously impossible to water in my ears. Use earplugs swimmers? Wax? What can I use? As the swimmers to use? I avoid freestyle, because the problem is immense pain. Only swim breast.
