Private instruction allows you to learn at a rate geared to you and your dog. Many of the most common behavior complaints are not covered by groups but are the focus of private instruction. While the total price of private training appears much higher than group classes, the rate may be closer than you think. The other seven hours may be spent watching someone else get help, or falling behind because your dog is distracted by other dogs. The real issue of cost and effectiveness rests with the overall results of the service.
Many pet owners benefit from traditional classes in the park.
Stubborn or difficult animals might not learn under group conditions. As with most things, a little research up front may save you time and money later. If the trainer advertises behavior modification for solving problems, ask for veterinary references. Many medical conditions mimic behavioral problems. If the trainer does not have a good working relationship with at least one veterinarian, he might not know the difference.
