On a recent afternoon, 3 - year - old boys and girls
assembled paper puzzles, strung beads, built sand castles and played with
large wooden blocks
in Room B of the Deerfield Park District Nursery School.
If your doggie door is
in a
larger room, you'll need to use an exercise pen — a multi-panel gate that can be
assembled to create enclosed areas of different shapes and sizes — to make an enclosure of the proper size just inside the dog door.
