So we have adopted a 18 month old staffy about a month ago. We kept the cats separate by using a baby gate on the stairs and they stay up there. We've been trying to introduce them slowly by bringing one down in a crate and letting our dog get near it whilst on a lead but she just goes absolutely mental, wants to attack them, barks constantly in a terrified kind of way and we just don't know what to do! The cats are obviously scared of her when she starts being aggressive and going for them so they hiss then which makes her way worse. I can't keep them apart forever and I have a baby due in October!!! Please help!!!
