I recently got a handy dogthat is made of a number of different panels that connect using a quick connect mechanism.
The reason that I got the dog in the first place was because I belong to the local chapter of a new surf club and part of my responsibility is to host the gatherings every month. Since I have a Bull Terrier I knew that if I didn't have some way to keep him contained I was going to have problems and I couldn't just lock him in the as there are people going in and out all the time.
While checking out some different options on the Web I came across this great site with these 100% steel frame Modular Panels that you connect to aGate to make a that meets your personal specifications. The cool thing is that the individual panels connect together into whatever shape dog you want. The galvanized frames and gate have 2x4 welded wire mesh covering them and are easy to keep clean. They also use a direct drill and weld method to attach the wire mesh to the frames to keep your dog safe from jagged protruding edges. There is a weather guard cover available to fit over the dog when you have it set up but since I only have it up for a few hours at a time I didn't get it. Now whenever I have guests over or there is anybody on the property I just set up my nifty quick set up dog and put my dog in there to keep him safe as well as my visitors.
