Dogs often make funny faces, including pulling their mouths to the side, when you scratch them due to a combination of physical sensations and emotional responses. The scratching can trigger pleasurable feelings, similar to how humans might react to a good massage. Additionally, this expression may be a sign of relaxation and enjoyment, as dogs often exhibit exaggerated facial movements when they are happy or comfortable. It's their way of communicating that they are enjoying the interaction!
