As of now, which edition is the latest of the AKC Complete Dog Book?

The latest edition of the AKC Complete Dog Book is the 20th edition. This edition provides comprehensive information on various dog breeds, training techniques, health care, and responsible dog ownership practices. The 20th edition also reflects updates in breed standards and may include new breeds recognized by the American Kennel Club, as well as modern approaches to canine care and training that have evolved over the years.

It's important to note that the editions prior to the 20th lacked these updates, and any editions beyond the 20th have not been published or recognized as current. This makes the 20th edition the most up-to-date resource available for dog enthusiasts seeking the latest breed information and training methods.
