Species-Specific Behavior and Development
Why species matters
Behavior is shaped by evolutionary history, sensory capacity, and developmental stage. Dogs are social scavengers with sensitive olfactory systems and read human gestures; cats are solitary hunters with strong territorial and predatory drives and are often stressed by change. Rabbits are prey animals that freeze rather than appease. Birds vary enormously: parrots are highly social and cognitively complex, while many small species are flock-oriented. Know the critical (sensitive) periods for socialization; puppies and kittens need broad, positive early exposure, and gaps produce lasting fear or avoidance.
Normal versus abnormal
Distinguish species-typical behavior from problem behavior. Normal canine behaviors include sniffing, chewing, digging, and vocalizing; normal feline behaviors include scratching, climbing, and hunting play. Problems arise when these needs go unmet or are punished rather than redirected. Stereotypies are repetitive, invariant behaviors often linked to barren environments or frustration. Separation-related distress differs from boredom or house-soiling for medical reasons.
Development stages
Puppies pass through neonatal, transitional, socialization, and juvenile periods. Kittens open their eyes around one to two weeks and socialize in a comparable window. Fear periods can make an otherwise confident animal suddenly reactive; trainers should increase support, not pressure.
Traps
Questions may describe a normal behavior as a disorder. Do not assume a dog's behavior is dominance; dominance is a relationship pattern, not a personality trait to punish. Also avoid anthropomorphism-interpreting behavior through human emotions rather than observation.
Rule of thumb
Before labeling behavior abnormal, ask three questions: is it species-typical, is it serving a function, and is the environment meeting the animal's needs? If all three point to unmet needs, the intervention is environmental enrichment and redirection, not punishment.
