Domestic dogs are the world's most widespread carnivorans, displaying an unparalleled diversity of shapes, sizes, and behaviors shaped by thousands of years of selective breeding. They possess an extraordinary sense of smell and a unique ability to read human social cues, making them invaluable partners in work, companionship, and therapy. While most live as cherished household companions, free-ranging and feral populations play complex roles in ecosystems worldwide.

Why interaction risk is low
Can deliver a defensive bite if threatened or cornered; always ask the owner before approaching unfamiliar dogs.
Why it is dangerous
Can inflict painful bites and scratches if startled, possessive, or defending territory, potentially transmitting pathogens like rabies.
How to recognize a risky encounter
Look for warning signs such as growling, bared teeth, a stiffened body, flattened ears, or raised hackles.
What to do
Avoid direct eye contact with an aggressive dog, stand still with hands at your sides, and back away slowly.
Responsible observation
Approach calmly: Let the dog sniff the back of your hand before attempting to pet it.
Read body language: Watch for a relaxed posture and wagging tail, avoiding tense or stiff animals.
Ask permission: Always consult the handler or owner before interacting with a working or leashed dog.
