A scared dog may cower, tuck their tail between their legs, or flatten their ears. They may also avoid eye contact, yawn excessively, or lick their lips.
An aggressive dog may stare, growl, snap, or bite. They may also raise their hackles or have a stiff body posture.
A wagging tail is often associated with happiness, but it can also be a sign of excitement, nervousness, or even aggression.
Yawning can be a sign of boredom, but it can also be a sign of stress or anxiety.
When interpreting dog body language, it's important to consider the context of the situation. For example, a dog that is wagging its tail may be happy, but it could also be excited or nervous.
