Instructions
Contact one of the many non-profit organizations that sponsor service dogs. The Delta Society and Assistance Dogs International publish lists of certified trainers and training centers, and may also be able to offer personal recommendations based on service dogs with which they have worked.
Consult certified dog-training organizations for a list of the trainers in your area. The Certification Council for Pet Dog Trainers and National Association of Dog Obedience Instructors requires trainers to take certification tests and obtain a specified level of experience.
Ask a person with a service dog where his dog was trained. Word of mouth is a good way to gather information.
Ask local pet professionals about service dog programs. Your veterinarian or dog groomer may know of a good program and be able to provide you with a referral. Pet professionals network with one another, so they have probably heard which service dog programs work. They may also be able to refer you to a client with a service dog, who can tell you about their experience.
Training Centers for Service Dogs
You can get a service dog in two ways: purchase an already trained dog or consult a professional training service for your pet. Some trainers and training services provide both, but no certification program exist for these services; so finding a quality program can be difficult. However, many canine-training organizations can provide you with a list of starting places that can begin you on your search.
