A dog’s body posture is a significant indicator of its current mood. When a dog becomes stiff, with muscles tensed and ears pointed forward, it could signal discomfort or impending aggression. This rigid stance, often accompanied by a hard stare, is a way dogs communicate unease.

Ignoring this sign might lead to escalation if the source of the dog’s stress isn’t removed or addressed. Being vigilant about your dog’s body language helps in preempting aggressive behavior.
