I have a pen like the one that Magnus sent the link for yesterday and my puppy Duncan loves it. I have put him in it since I got him and have never had any trouble with him staying in it. The only 'problem' I have with it is when I come in the door (I come in the kitchen door and the pen is in the living room), Duncan gets so excited, that he starts jumping in the pen and he moves the pen across the living room floor (it is hardwoods. If you have carpet, maybe it wouldn't move as much). But he stays in it and it doesn't open or come unzipped. |
