I would definitely not move there- the people nxt door are probably not going to be good or nice neighbours because their dog is aggressive- its how a dog is reared that makes it aggressive- so what does that tell you about those people?? My DD had a staffie from a pup- sadly it died last year, (getting on a bit and had developed illness) BUT, it was the loveliest, softest dog you could meet, they had dog before the kids, but still it wasnt jealous,(it even used to let my GD pull herself up on it when she learned to walk) it loved all the visitors/visiting kids, and never barked or growled at them.It even got me used to dogs, and im a cat lover really.As i said, its the people, not the dog, so really, if their staffie is aggressive, then they too are aggressive.Id say its a big mistake to move there.
