Dogs may vocally warn away dogs encroaching on spaces they consider their own turf for security reasons.
Territory Alerts
Barking can reflect insecure pups feeling overwhelmed by sights, sounds, smells of unfamiliar dogs when needing space.
Stress or Anxiety
Leashed dogs strain against restraints in their eagerness to investigate passing dogs, triggering demanding barks.
Frustrated Greetings
Dogs experiencing aches or ailments may snap or bark more easily when another dog startles or jostles sore spots.
Pain or Illness
Some dogs adopt guarding roles by sounding alarm barks if newcomers seem too rambunctious around their delicate housemates.
Protective Instincts
Fences provoke "fence fighting" as dogs bark eagerly at dogs they can see but not access to play together.
Barrier Frustration
Obedience skills, structured socialization, and removing reinforcement can reduce unwanted barking over time.
