My brother in law died on Saturday and we have now got his 2 staffies. One bitch spayed and one dog unneutered. They are 12 years old, brother and sister and always been together. We have a 7 year old sprollie and a 3 year old pointador, both bitches and spayed. The staffies are dog aggressive, the male more so than the bitch. At the moment they are shut in a separate room (not all the time) so that they do not make contact in the house with our dogs. We are starting to walk them together (staffies on the lead), does anyone think there will be a time when we can have them in the house together in harmony? Any tips would be most welcome.
