1. **Body Language**: Aggressive dogs often display stiff body posture. They may stand tall with their tails raised and rigid, and their ears may be perked up or pointed forward.
2. **Growling and Snarling**: Vocalizations such as growling, barking, or snarling can indicate that a dog is feeling threatened or aggressive. Pay attention to the tone; a low growl is often a warning sign.
3. **Bared Teeth**: If a dog shows its teeth, it can be a clear sign of aggression. This may be accompanied by a curled lip or a snarl.
4. **Direct Staring**: Dogs that are aggressive may fixate their gaze on a person or another animal. This intense staring can be a challenge or a sign of dominance.
5. **Lunging or Snapping**: If a dog lunges towards someone or something, or snaps its jaws without making contact, it’s a clear indicator of aggression.
6. **Raised Hackles**: The fur along a dog’s back may stand up when they are feeling aggressive. This is known as piloerection and can be a sign of fear or aggression.
7. **Defensive Posture**: A dog may display a defensive posture by crouching low to the ground, tucking its tail between its legs, or rolling onto its back in a submissive manner while still showing aggression.
8. **Resource Guarding**: Dogs may become aggressive when they feel their possessions (food, toys, space) are threatened. They may growl, snap, or bite if someone approaches them while they're eating or playing with a favorite toy.
Understanding these signs can help you intervene before a situation escalates. If you notice any aggressive behavior in your dog, it’s important to consult a professional dog trainer or behaviorist to address the issue safely and effectively.
