If Sunny was one of my pups and I read about this I would be freakin "Sunny is socialized regularly (about 3 - 4 times a week) with my neighbor's dogs. He has two massive (110+ lbs) cane corsos. Extremely well behaved and they both love sunny" If some thing happened , even in play, you have two dogs , tight with each other, reacting with one mind . Accident just waiting to happen.
you haven't got a chance .
this is not what is meant by socializing .
