Physical Cues

Pay attention to your dog’s overall body language; a happy dog will have a loose and relaxed body, while an aggressive one may stand stiffly with raised fur.

Look for signs of playfulness like bowing down, play-bowing, or inviting you to play with toys when they show their teeth.

Facial Expressions

Focus on the rest of their face – are their eyes relaxed and soft, or tense and focused? Happy dogs often have a relaxed face with a slightly open mouth, while aggressive dogs have a wrinkled snout with narrowed eyes.

Observe the position of their ears – forward or relaxed ears indicate a happy mood, while pinned back ears could signify aggression.
