Start as early as 8–12 weeks for puppy socialization classes. Basic obedience can begin at 12–16 weeks. The critical socialization window closes around 14–16 weeks — early exposure to people, dogs, and environments during this period shapes your dog's temperament for life.

Look for positive reinforcement (reward-based) trainers. This is the method supported by veterinary behaviorists and animal welfare organizations. Avoid trainers who use punishment, shock collars, or dominance-based techniques. Ask about their methods before booking.

Trainers handle obedience, manners, and mild behavior issues. For serious problems — aggression, severe anxiety, compulsive behaviors — you need a certified animal behaviorist (CAAB) or veterinary behaviorist (DACVB). Your vet can refer you if needed.

Basic obedience: 6–8 weeks of classes plus daily practice. Behavior modification: 3–6 months depending on severity. Board and train: 2–4 weeks intensive. Remember — training is ongoing. The classes teach YOU how to work with your dog consistently.
