Kim Trafton has been training and titling my dogs in field events since 2000. I totally trust her. She doesn't teach classes but sometimes holds training days and opens them to interested people who want to come throw birds for each other and learn a bit- sometimes someone will be teaching puppy table manners, sometimes someone else will be working with the kids, and someone else will be doing bird boy training. And pot luck dinner around a fire- lots of fun! She specializes in training conformation bred Goldens in field and obedience. A little niche that is helping to preserve our precious breed's bird abilities!
Obviously I am one of her biggest fans,and would suggest you talk to her about a puppy and it's training.
