I like presas but I seem to see a lot of sway backed ones, I realize they are a long bodied breed but that shouldn't equal a bad topline. Maybe it's the pics but both the dam you posted and your dog appear that way. How's their temperment?

I looked at the kennel you got them from and they look like a byb, no health testing, serious showing or working, some pics of the dogs working sleeves in a backyard but that's nothing to write home about. Unless there is something I'm missing they look like a typical peddler who jumped on the guardian breed wagon.
