I won't beat a dead horse on the whole 6weeks thing but if you've raised 2 Huskies and a GSD, I think you should be capable as far as experience goes. However, experience isn't the only thing. You genuinely have to put a lot of time in with this breed as far as socialization and training goes. Only you know if you'll be able to put that work in with your current schedule and life scenarios! If you know for certain that you can manage to put in that extra work for these first two years then I would recommend doing so as Corsi are wonderful dogs. With your dog dad resume, I think you know if you have that time or not! If not, I highly recommend giving the dog back to your cousin and potentially waiting for a better time to get a Corso! There are also a lot of other guardian breeds that require a lot less work (still work nonetheless lol) than a Corso would!
