No you're not being stupid at all :)
of course everyone has been an inexperienced owner at some time in their lives
Bullys are strong dogs and "some" do have issues with other dogs which not everyone realises. The rescue centres have to err on the side of caution so that the dog isnt returned or rehomed. Have you visited any sbt rescue centres and maybe help out. That way you would gain experience and decide if this really is the breed for you.
Where do you live by the waY ?
