ok this has happened twice now. My Frenchie appears to be absolutely spooked by something. Both times it's happened in the dark. His front legs go wider, and his body won't stop shaking. His eyes are wide and he's looking around but it's like he is petrified od something. It's taken me about 5 minutes to calm him. I've googled it, and not sure what it is as he hasn't peed himself. Freaking me out. Can anyone help? (He is 2 1-2) no health problems.
