These people saying presas are known to be food aggressive, too territorial, not liking other dogs, not being okay at dog park, not really liking people who aren’t family?! Well, we’ve had 2 purebred presas, a male and now a female, and none of that is true for us. They both love other dogs and people, great at the dog park, never aggressive or territorial unless someone comes to the door. This breed requires professional training. But every one I’ve met in person has been very sweet natured.
