| Dog aggression and good mothering are two entirely different things. A bitch that lacks mothering skills should never be rebred. That does tend to be passed from mother to daughter so her daughters should be considered iffy on breeding as well.
Dog aggression however is from an completely different area of behavior. Whether it is a problem or not depends upon training and leadership of the owner. A breed that was not developed to run in a pack (such as hounds) or to work in a pack is often dog aggressive but that only shows if the dog has not received proper training and disregards the owner/handler. Neither the GSD or the Rottweiler was bred to run and work in a dog pack, but were bred to work with a person. |
