I agree! A lesson on dogs playing would be very helpful and might cover situations where 3?several? dogs must live in a home with existing dog(s) for extended period of time on short notice. In most of the cases I can think of, the dogs might be somewhat familiar with each other as other family members might be called upon for care as opposed to boarding at a kennel.
– a lengthy family illness
– people move and unable to take their dog(s) for a time
– someone goes on extended holiday where dogs aren’t welcome
– change of employment that requires long hours away from home
