Well I had a lot of reservations towards my presa canario puppy being a good guard dog/personal protection dog and today I am completely sold. He is everything I wanted and more. I'm not sure if a switch flipped or what but he's much more confident a lot more suspicious of strangers. He's barking more when strangers approach he's more defensive and territorial.
