I think every dog has a rep.....some worse than others for sure. The ones I have heard most are:

Pitbulls - very aggressive dog...not good with children, fighting dogs

Rotties-bad temper, not good with children

Poodles-very yapping

Ok so now in their defence (unfortuntely)

Pitbulls-my friend had 2 of them and 3 children. The biggest babies I have ever ever seen.....very protective on command though. Um and the kids are still alive......imagine that!

Rotties-have 2 of them......very protective of my friends kids...big babies. Have met tons of rotties-very good temper and most of the people have children and they wern't harmed at all....imagine that!

Poodles-my girlfriend has 1 and the only time i ever hear that dog bark is when someone comes to the door, or you are playing with her...........
