Betty Regina Leininger was born in St. John's, Newfoundland, Canada. Her experience in purebred dogs began with the breeding and exhibiting of German Shepherd Dogs. She co-founded the Newfoundland (All-Breed) Kennel Club in 1962 and has been active in many kennel clubs over the years. She served as a Board Director of the Atlanta Doberman Pinscher Club in the late '70's, was a member of the Waukesha Kennel Club in the mid-80's and has been a member of the Doberman Pinscher Club of America since 1971.

Upon moving to the United States in 1970, Betty became an AKC licensed Professional Handler and a member of the Professional Handlers Association. During her extensive handling career she guided the show career of many top winning dogs. Throughout the 1970's Betty also guided the breeding programs of many of her showdog clients.

After a highly successful multi-breed career in handling she became a judge in 1983. As a respected judge of Working and Non-Sporting breeds she has judged widely both domestically and internationally. Betty has judged the Doberman Pinscher Club of America National Specialty on two occasions, the Doberman Pinscher Top 20, the Akita Club of America National Specialty and the Rottweiler National, to name a few. Her international judging has taken her to Canada, Mexico, Argentina, Brazil, Taiwan, Japan, Australia and New Zealand.

In the late 1970's Betty co-authored a book entitled, Preparation and Presentation of the Show Dog, under the name of Betty R. Brucker. She has conducted handling seminars throughout the continental U.S., Hawaii, Alaska and New Zealand.
