I need a regex expression which returns the start to the x=ANIMAL for
only the x=Dog fragments so all my entries should be start ...
(something here) ... x=Dog . So I am really interested in fragments 1
and 3 only.
My idea (primitive) ^start.*?x=Dog doesn't work because clearly it

The following *may* come close to doing what your revised spec

The re module-level helper functions cache expressions and their
