Children under the age of 12 have difficulty with their own impulses and consistency so if children are doing actual training it should be with the guidance and supervision of an adult. Adults should think of their role as coach or referee who sets the rules of play, calls for fouls and time-outs and provides adequate protections and quiet-time for pets as well as children.
Children can really benefit from the structure of feeding, cleaning and walking responsibilities, and they offer the necessary socialization of dogs to a bustling atmosphere! Be sure to teach children appropriate ways of petting and handling!
Simple tricks and commands that are easy for children to try can include sit, paw, and so-on and they are fun to share with friends!
