Behaviour and Training

Parson Russell Terriers and Fox Terriers are smart, energetic dogs with strong hunting instincts. Their behavior and training needs differ in subtle but important ways.

Training Difficulty

  • Training Parson Russell Terriers can be challenging due to their stubborn nature. You’ll need patience and consistency. Fox Terriers are also independent, but may be slightly easier to train.
  • Start training both breeds early. Use positive reinforcement methods. Short, fun sessions work best for these active dogs. Avoid harsh corrections, as this can make them resistant to learning.
  • Socialization is key for both breeds. Expose them to various people, animals, and situations when young. This helps prevent fearfulness or aggression later on.

Intelligence and Trainability

  • Both breeds are highly intelligent. Parson Russell Terriers are quick learners but can be stubborn at times. Fox Terriers are equally smart and may be more willing to please.
  • Keep training sessions varied and engaging. These dogs get bored easily with repetitive tasks. Use puzzle toys and interactive games to challenge their minds.

Hunting Dogs and Prey Drive

  • Parson Russell Terriers and Fox Terriers were bred as hunting dogs. They have strong prey drives and love to chase small animals. This instinct can make off-leash training difficult.
  • Teach a reliable recall command early on. Use a long lead for safety during training. Never let them off-leash in unsecured areas.
  • Channel their hunting instincts into appropriate activities. Scent work, earthdog trials, and agility can be great outlets. These activities satisfy their need to hunt while keeping them under control.
  • Be cautious around small pets. Proper introductions and supervision are essential. With training, many can learn to coexist peacefully with cats and other small animals.
