Can my small dog play in the large dog playgroup (or vice versa)?

For safety reasons, small dogs stay in their own designated play areas, boarding areas, and outside area. It may be true that your big dog prefers to play with small dogs (or vice versa), but the same may not be true of other dogs in the group. Additionally, placing dog of different sizes in the same playgroup would increase the chances of accidental injury, and we obviously want to reduce the possibility of that as much as possible.
