Cane corso/presa canario mix

Me

So I got a cane corso and presa canario puppy. He is so sweet and gentle. He is 5 months old. We have started training him already (been home for 3 days now). Anyways, we heard/read more bad stuff about this mix. All of these were personal opinions. I wanted to see if anyone had any experience with this mix or known someone? I am a firm believer of properly training a dog vs blaming the breed for bad behaviour
