Exactly the same breed that killed the woman in the San Francisco apartment building.
Who needs such dangerous dogs? Maybe to guard prisons, but a more manageable breed like a Shepherd is better for your home and family.
These are wonderful dogs and people shouldn't be condemning a whole breed by the actions of a few. I have 3 and they are great around my kids, especially my 4 year old twins, who rides them like horses. It's a pleasure to see the dogs drag the kids around the yard on their play things. We have a sled and a wagon that the dogs pull. I can leave the kids with these dogs when I go to town and trust me, nobody is gonna come and cause harm to my kids. My neighbor's German Sheppard got into our yard once and my dogs destroyed that dog to keep my kids safe. (/s)
