Your family sounds very much like ours! At the moment we have seven dogs between four houses but at the most we had 13! Generally speaking we don't take the dogs with us for family gatherings because having several dogs which aren't "done" means that they have a tendency to squabble when they think their territories are being encroached upon but they do get walked together quite regularly and spend their summer holidays together! It's interested finding caravan sites which allow a large number of dogs at the same time but they do have a fantastic time together running on the beaches and playing in the sea! I can't understand anyone who sends their dogs into kennels whilst the rest of the family go on holiday ... I like to keep my family together!
