I would be leary, but I have two young children. My issue with these dogs is that they are often used for protection and children often act irraticly. They move quickly and the dogs can't predict what they are going to do and therefore think they are a danger and attack. My kids also have no fear of dogs and we continue to work with them about approaching dogs they don't know slowly and asking if they can pet them then letting the dog smell them.
The problem is that they usually go running at the dog and stop about a foot away and then slow downa nd ask. That's a little too close if the dog doesn't do well with kids! We try to talk with them about it and are trying to find a balance but we also don't want them afraid of every dog they see. They do what we ask by askign the owner if they can pet the dog and letting the dog sniff them! Goofy kids!
