This week on Genome Barks we welcome Pat Hastings, a lecturer on canine structure, form and function, and the 2001 winner of the Doberman Pinscher Club of America Lifetime Achievement Award.  Mrs. Hastings discusses her structural evaluation process, the importance of breed type, health and temperament when evaluating a litter of puppies, and her caveat of never letting pieces be more important than the whole.  Mrs. Hastings also describes the developmental milestones that breeders should watch for.
