A female colleague randomly asked if I had a backyard. She said she might bring her dog over for a run in it. Am I looking too much into this?

Iv liked this colleague for a while she is 29 im 48 it just seems strange lately she has said a few things that have got me thinking. She said her dog would be ok in the backyard running around. Does that mean she wants to spend time with me? Or am I over thinking as usual?
