One of my 2 labs has an uncanny ability to read me. If I’m thinking about going to the kitchen for a snack, she often gets up and heads for the kitchen before I make a move. Same with going for a ride.
She also figured out how to unlatch a gate, so now I have a padlock on it. She hasn’t figured that one out yet, but I’m sure she’s working on it.
Your dog is reading your body language. They are experts at it.
Our lab/golden mix has the same ability when it comes to Mrs. Mad’s activities. Spooky how well that dog can read her.
