Vitaly- The Dam of my Corso (Capone) is Quebec. I believe that Carlos from Rivale Cane Corso has more of a working line then Apex who shows more in confirmation. Amore is the partner kennel of Rivale and has nice dogs as well. Boguart is looking great! He is out of Mac! Mac is truly a Mac truck and one of the best working dogs in the country. I would be comfortable to say that either kennel is great. Rivale being my frist choice. I will try to post pictures of my pup Capone. He just turned a year the beginning of October and about 115 pounds with a head that accounts for half of that weight! HAHA! Let me know if you have other questions. By the way I do know others here local to me that have dogs from Rivale and have great drive in working and look good doing it. Good luck!
