Lucy is confused

My dog was so funny last night! Me and hubby were looking through Netflix and of course, our dog Lucy had to jump up and join us!! She is such a cute thing! A pain at the same time! LOL

So we are looking through the things to watch and it makes this noise  - if you've got it or used it, you'll know the little noise.

Lucy suddenly looks at the screen with a confused look - every time we make the TV make the noise! I
love my girly!! <3  <3  <3
