A very popular service that I provide is a 1½ hour one to one course for puppy or dog owners about managing and training their new companion. Because these are one to one classes at home they can safely begin any time from eight weeks of age when the puppy is at peak learning ability. Mass training classes teach a dog to behave in the presence of other breeds and sizes of dogs, and to behave in a church hall, but do not teach the dog to behave at home, in the park, or with your visitors and children. A home visit is the preferred choice in almost every case.
