You Lied To Me
This is the face of a dog that realized they were tricked into going to the vet. His owner probably coaxed him into the car with treats and toys only to drive him here. It’s clear that this dog knows what the linoleum tiles and people in medical garments can mean one thing and one thing only: the vet.
The look on this dog’s face shows the sting of betrayal and now distrust towards his owners. He also has never been more disappointed in his life and will never get into a car again.
