I had a CORSO, best dog I ever owned period. I have had Rotties, a Pitbull and I currently own Olde English Bulldogges...which I love, but my Corso was amazing.
He was house trained in two weeks, off leash trained at 8 months and level trained at 1.5yrs. A great friend, a strong quiet defender, my baby, and a loyal companion.
I am getting one again, but my wife was afraid of dogs, which is why I got OEB's for her to get use to bigger dogs from pups and to stubborn personalities so that she can understand the minds of the Corso....great family pets, but they will run yo over physically and mentally if you let them.
My bot was 32" at the back and 166lbs at 3yrs, with a 26" head...the smartest dog I have ever owned! I had him for 9yrs.
