Best brand / type of puppy exercise pen that won't slide around?
Hi all,
My wife and I are planning on bringing home a lab puppy sometime in the next few months and I've started to review the different brands / types of puppy pens out there. We'll be crate training the pup, but I want to provide the pup with a bit more room to move around when we have to leave him home alone for a few hours. Would like to have the crate either in the pen or one of those built-in pen/crate combos so the pup can choose pen or crate. Does anyone have recommendations on the best brand or model of exercise pen out there? My main concern is that I want something that the puppy won't be able to push/slide around across the ground (bang into walls, etc.) I'm hoping to use this pen until the puppy is 10 months old or so, so I'm looking for something that is fairly strong / heavy duty. I'd prefer it to be free standing so I don't have to anchor it to a wall, etc.
Thanks!
