I have a carne corso among them. I specialize in guard dogs and bree d a total of 7 breeds but will be getting another pair soon
I have
rottweiler
dogo canario
cane corso
dogue de bordeaux
argentine dogo
tosa inu
Alano

Alanos are exceptionally rare and have no current club except a pure alano club. They are like great danes on speed. Great big guys, but with muscel. They are ALMOST as tall as a great dane. but exponentially stronger and with a more intelligent looking head.

I plan on acquiring several other breed pairs in the future. All but the dogue de bordeaxs that I currently own are breed by me for at least one generation.

I am thinking of getting a neopolitan mastiff and a fila brasileiro

I have obviously had pit bulls with this ling of dogs. but have never breed them. Just had in youth and before I got into breeding. had 3 all males
