Nice Corso bro I've got one who turned 10 months yesterday he's 121 pounds already I got him from one of the top breeds around my area and couldn't be happier with the breed Love the Corsos
He probably got bit by one at some point in his career, lol. I'd be wary of a vet who "wasn't a fan" of a certain breed, it just bothers me for some reason. I had one who insisted on muzzling my GSD's because he was bit by one once, I walked out and found a new vet.
It's like a doctor saying he isn't partial to Italians or blacks! It's racism, flat out. Just dog racism. Fk that vet, find another one.
And I love the black/dark one on the right. Very lab looking head. Awesome dogs. My neigh or had two growing up. Absolutely huge, but sweet as can be. Enjoy every minute brother.
