No offense taken. I prefer the ears cropped too. I drive over 4 hours to this one vet to get my ears done. They are the best that I know that is remotely close to me.

How big of a dog you want? I have a female pup that was over 110lbs. She is on the large side for a female but certainly not the largest. The average male is around 125lbs. I have a friend that has 110 acres farm. When I visit him with my dogs we run them with his golf carts. My dogs and his dogs cam outrun the golf cart. My son takes them for bike rides with him. Of course they can outrun the bike, but he has on leash and then they just keep up with him. But with the golf carts it is all off leash. They can give us a head start and pass us by and then wait for us only to leave us again.

But another big dog you can look at would be a Tosa, Bull Mastiff, or South African Boerboel. Thise are a few that come to mind that are larger than a presa.

I've had Rotts, American Bulldogs, GSD but the presa is my favorite of them. They are special. I haven't owned one but I like the caucasian ovcharka. The only thing that kept me from getting one is that I don't want another long hair dog that shed a lot. I have an ACD that I rescued. I love him, but the hair everywhere is too much.
