I saw one of these at the dog park today and it made me curious about the breed. They seem to be gaining popularity. I like their looks but I don't know much about them at all. To those who own them, what's it like to live with a Corso? Do they coexist well with other dogs (the one at the park surprised me with how dog-friendly she was. I always expected them to be a bit belligerent with dogs)? What's their activity level like?
