One of my doggie friend Baby have a situation. She thinks that her mum might have installed cctv at home to spy on her. Baby, I'm gonna teach you how to check if there really is CCTV installed in your home ok.
First, you gotta climb up real high so that you can reach the highest point to your home (e.g celling)
Then, use your paws to feel for any unusual objects... If there is no camera, the celling should feel smooth.
Then use your doggie nose to smell for anything fishy...
If there is nothing unusual then you are clear of any suspicious spying equipments in your home.
Hee Hope this helps. :P
