This is such a hard subject and while I love so many of the "fighting breeds" I have to say I would never trust them , even when raised by a highly knowledgable dog person , and this is why . My brother in law had a rottie , from a reputable breeder , raised in a loving home , very obedient , raised with 4 small children , NEVER had any problems with him . One day my oldest son , 1 & 1/2 years old at the time , WALKED past him . Just walked , didn't tease him , or go near his toys or food or anything , just walked past him and that dog lunged violently and went for the back of my sons neck ! Thank God my husband was RIGHT there and beat him off of my son , so there were only small wounds or my son would've been dead . This gorgeous dog that for years had such a stable temperment and so loving with children just snapped ! My husband and I will never allow our family around "fighting breeds" because of this . It's a very personal issue for us . Just my 2 cents .
