At Green Collar K-9, green dog development begins at seven weeks of age for selected puppies. Each is given a thorough and detailed assessment. Comprehensive assessments detailing socialization, exposure and response to stimuli are documented weekly through three months of age. Monthly assessments are conducted through six months of age. Individual files are maintained and include health records, photos and videos of each puppy. Working with experts in all facets of K-9 development from conception to completion, gives us an unrivaled understanding of what creates excellence in a working dog candidate.
