Uses for a Dog Exercise Pen
Most exercise pens are made of wire mesh, chain link, or sturdy plastic and are collapsible and portable for a wide variety of uses. Take it to the park so Rover can play in peace, and you won't have to watch his every move in public.
You can also set up an exercise pen in your home during the day if you work outside the home. This gives him more room to move around than his crate. Make sure to include his water bowl and some food.
If your dog is large and primarily an outside dog, you might even want a dog run, which is just like an exercise pen, only much larger. This gives big breeds plenty of room to stretch their muscles and get the blood flowing, while at the same time staying protected and safe from other people or even traffic. Dog runs tend to be more permanent than exercise pens, but are easily installed or even constructed on your own.
Dog Exercise Pen Accessories
Depending on how you use the Dog Exercise Pen, you'll also find a wide variety of accessories to make your dog's exercise time more comfortable. 
Many pens come with sun shades to keep Fido from the extreme heat, and others are expandable with extra snap-in sections so you can customize the space to your dog's needs. If your dog is a great jumper, you may want to get a pen with a roof to keep him confined.
No matter what kind of Dog Exercise Pen you choose, it will be better for any animal than tying it to a tree or a lamppost. Tying your dog up can be dangerous because he can wind the rope or chain around his legs or even neck. It also leaves him open to dangers like other dogs, teasing children, and automobiles.
In the end, all dogs need plenty of human interaction and attention from you and other family members, and making the pen his permanent home would prevent that. Dog Exercise Pens should be a temporary way to keep your dog confined if you're out for a couple hours or maybe a day or so.
