I am a Kennel owner/operator, and I can tell you first hand Tosas can be whatever you make of them. Our dogs are unshakable guardians that double as kid's "ponies" on the holidays. You will have a hard time trying to find a better family dog. Sometimes it is easier with younger dogs to get them socialized and sometimes it is not, that depends on the dog. But the ultimate factor is whether or not you're gonna tolerate dogs that don't like other dogs. In this kennel, we have Tosas from Korea, Japan, The U.S., and Europe, and they all come to the same bottom line: If the dog thinks it's the leader it will make up it's own rules and live by them, which may include bad manners with other dogs. If the owner is the authority figure, they make the rules, and one of our first rules here is dogs can't start fights. Our Tosas have lived with my mom's poodles, my sister's labs, and other family member's dogs just fine.
