Is a presa canario the right dog for me?

[CJL]

Reposting this question because I didn't give enough information the last time. I have previous experiences with large dogs. I had a Newfoundland dog who died last year and a Doberman who died 3 years ago. All my dogs were very well trained. I seen a page on
Facebook that breeds presa canarios and I fell in love with those type
of dogs. I heard the dogs can be dangerous and I am looking for more information from someone who has one or who's been around one. I can't go to a breeder and ask because they are very hard to find where I am living and this why I'm posting the question online. I have a house with a very big backyard. I also have a 6 month old daughter and a shih tzu puppy that I bought for her. (I take care of him.) I'm good at handling large dogs I just want to know if my daughter and my shih tzu will be safe if I get one. Just looking for more information. My daughters and my shih tzus safety come first. Although people say a
Doberman is a dangerous dog but I've had no problem with mine. I don't know much about the dog and I am just looking for more information before I go ahead and buy one.
