Jack Russell Terrier personality
Jack Russells are fearless, clever, and inexhaustibly energetic, demanding plenty of work and play to stay happy.
But breed is only the starting point. Two Jack Russell Terriers can have very different personalities — which is why the CPTI model measures each dog as an individual across four trait dimensions, then maps them to one of 16 personality types.
Sociality — Outgoing (O) vs. Selective (S)
Does your Jack Russell Terrier greet every dog and human like a long-lost friend, or warm up only to a chosen few? Neither is better — but it changes which playmates and settings your Jack Russell Terrier will love.
Exploration — Adventurous (A) vs. Predictable (P)
Some dogs need new trails, new smells, new everything; others thrive on ritual and routine. Knowing where your Jack Russell Terrier falls tells you how to plan walks, travel, and enrichment.
Cooperation — Affiliative (F) vs. Independent (I)
Affiliative dogs work with you and live for your approval; independent dogs solve problems their own way. This axis shapes how your Jack Russell Terrier learns best in training.
Emotionality — Relaxed (R) vs. Vigilant (V)
Relaxed dogs shrug off surprises; vigilant dogs notice everything first. It determines how your Jack Russell Terrier handles busy parks, guests, and new environments.
