I respect your opinion and this is no way intended to offend you. To say the rottie is dog aggressive is not true, to say the rottie needs a hard hand is not true. Any dog at any time can be aggressive, I don't truly ever believe a dog needs a heavy hand. Its about bonding and training. I owne rotties for a long time and breed them. I never had any problem mentioned above. If you project fear a rottie will pick that up instantaneously. The corso has rottie blood in it, along with other breeds and the neo, well many of the lines do. If you study the history you will see both breeds intertwine in the legendary roman days. This is one reason why I left the breed and the ICCF, was the fact of constantly comparing the rottie to the corso. At this point in both breeds history, the corso will have a long way to go to catch to what a rottie is and can do. I do like the corso and owned and breed them. I showed them and worked them. Great dogs, but nothing can ever replace a well breed, cared for and trained rottie. The corso at this point is too inconsistent, from reverse scissors, scissors, even bites, to height, weight, head type, muzzle type, the confirmation is totally off. I love the breed and I wish to see it succeed. The corso is the breed of right now, unfortunately if there is no unity then the breed is doomed.
