Welcome to Big Chief Service Dogs!

Big Chief Service Dogs is owned and operated by Bill and Mindy Pereira of Bellevue, Idaho. Service dog trainer Bill Pereira has been training retrievers for 40 years. Over the last 8 years he has specialized in training Labrador Retrievers as Diabetic Service Dogs. A Type 1 insulin-dependent diabetic for 47 years himself, Bill understands the need for accurate ways to avoid Insulin Shock or Hypoglycemia.

Our dogs live in our home with us from the beginning of their training. We train our dogs to be confident, focused and ready to detect and alert their diabetic owners to hypoglycemic episodes in their daily lives. We primarily train English Labrador Retrievers. The English Lab is the perfect breed for a service dog as they are extremely sensitive, very mellow, have great minds and temperaments, and are easily trained for diabetic scent training.

Please continue to browse our web site to learn more about how Diabetic Service Dogs can change and enhance your life, and don't hesitate to contact us with any questions or comments you may have about these life-saving companions.

Thank you for visiting!

Chief has saved Bill's life many times and prevented him from going into insulin shock. He has become a valuable member of our family and we can't imagine life without him.
