The dog never showed aggression to anyone, like growling. All bite incidents were "explainable" from a logical perspective.
After this event, there will be no dog anymore. I can't sleep knowing that a family, living on my farm has a powerful dog, after all, I'm responsible.
The day I'm single and living in the wilderness, I may have such a dog again. No visits, no children....just me and a monster of a dog.
With guard dogs you really have to know what you are doing, can't recommend such a dog to a family. The biggest problem is, which breed of dog is a good family dog -but also protects? The answer is: There is no such dog, period. UNLESS he is from a first world breeder who has a track record in breeding "aggression reduced" dogs, the US is leader in this. Their rots, pitbulls, bull mastiffs and american bulldogs are lovely. Buy any of those breeds in Brazil -or Argentina, you may get the unmodified version -and believe me, they are NOT family dogs at all!
