Query: Small containment area.

The Iris CI-604 Indoor/Outdoor Plastic Pet Pen, 4 Panels is a good containment facility for small dogs. Though it is not a big area, there is enough room for your dog to play a little, eat and sleep. The pen is easy to assemble and disassemble for storage. It allows you to keep your dog in an area where you can keep an eye on them, even when you are doing chores. It is light and portable and I have found that it doubles as a gate to close off an area of the house you do not want your dog to go into. Finally, you can increase the pen area by buying extra panels as required. Great product for short/term penning.
