Can animals sense a walk in?
 

I've been trying to figure out why my dog has been acting differently lately and came across some information that points out that a possible walk in has happened.

If said thing has happen could that explains why suddenly she acts nervous or shakes a lot and tries to hide under the bed? I've had her since she was born in july of 2007.

look at yourself as what am I doing differently before she started to act like this and afterwards... I think a walk in is more concious of things than you are now, no offence here.
