My question is that I am trying to determine what dog is the Alpha dog out of my three dogs. I have a 2 year old Male Presa Canario (Mastiff), a 5 year old Male Pit Bull and a 10 year old female Pit-Bull mix that I am pretty sure is the Omega. But the two males that I have had since birth exhibit Alpha traits. My Presa is pushy, shoves the other dogs out of way and does not allow the other dogs any affection before him or maybe on somedays not at all. He is not food aggressive toward me or the female dog but will not let the male Pit-bull eat his food/and then takes ownership over the food. I must separate my male Presa or he will be very vicious towards my male Pit bull.
