We've got a litter of second generation "Dane-Heavy Golden Danes," meaning that they're 1/4 Golden Retriever, 3/4 Great Dane, (Father is 50/50, mother 100% Dane). These pups are 35 to 40 pounds at 8-weeks of age, so a good Whelping Pen was a must!This is a fantastic product. It's easy to assemble in multiple configurations and we purchased the large size whelping pen - plus - the additional largest sized play area, (which has been a godsend, since we put a large-sized puppy "Loo" (dog litter box with the fake-grass astroturf-looking stuff), at that end to keep filth separate from food/sleep/play areas. It's worked fairly well.The edging rail system is cool and easy to assemble/disassemble, with the latter being the most important for us, as we didn't get much use out of it. I see what they were going for there - something to keep small pups out of the "wedge" where they can get smooshed by a nursing mother - but for our sized pups, this was convenient for about the first week after moving them from their "puppy pool" to this at 1-week.Once our pup's eyes opened and they became mobile, the safety rail became a booster to enable a crafty pair of them to jailbreak constantly!I LOVE and HIGHLY recommend this pen. If you've got small or medium breed pups - even large breed - this thing is going to be AWESOME for you!If you're rearing a litter, (especially a large litter - ours is 13 face-licking, gangly lunatics), of GIANT BREED dogs, just know that, by 5 or 6 weeks, the more athletic and crafty of your litter are going to find a way to escape over the wall! (We've got 2 of them that are like Michael Schofield on PRISON BREAK!) Be sure that the surrounding room is also Puppy-Proof, or you'll be chasing puppies everywhere.I do hope that the manufacturer will consider making a "Giant Breed" version in the future that will take wall height into consideration as well as length. I understand that using multiples of the same panel is price-effective, versus the cost of producing and warehousing much small numbers of different-sized panels, but even offering a panel-extension that fits into the pin holes in the tops of the upright panel junction mounts would be a good offering.Personally, I've purchased dowel rods and plastic screen from my hardware store and created a screened extension to deter the escape-artists from going over, but I don't think it'll hold up for long. Just hoping we're able to make it to 8-weeks and send most of these crazies to their forever-families!One thing to note, (and I should've taken a photo of this), the upright panel junction pieces are AWESOME! They have a hole in the center of them that goes to the floor. I went to my local Farm & Home Store, (Bomgaars), and purchased two, 4-foot metal rods, (in the welding section), and bent them each 90-degrees in a vice at about 16" from one end. I then bent a hook into the last 3 inches of the 16" bent rod and used that to secure metal-cone heat lamps to hang above the whelping pen. I then used automotive wire harness covers, (the long, black, ribbed plastic hose looking stuff with a slit down the side), to secure each lamp's electric cord to the rod, all the way to the pen's plastic upright and inserted the rod into the hole to the floor. (That was then all wrapped with electric tape to keep it secure).This gave me two heat lamps on poles that hung above the pen, which I could simply swivel out of the way when not in use, (to make easy access for changing out blankets or later gruel bowls, etc.). It worked GREAT!!!If you do this, just make doubly-sure that you secure the wiring like I did so that puppies cannot access it when they get bigger, (although in my case, we didn't need the heat lamps at the point that the pups were big enough to start chewing stuff).Final mention - If you get this, it's handy to splurge for the extra "Play Area!" Like I mentioned, we use that for a potty area. The ability to close off the pups in one area while cleaning the other has been AMAZING! Well worth the extra investment!

This was a great addition to add to the whelping box! I wanted a little extra space for momma to be able to have constant access to water without having to worry about the babies spilling it. She seems to like having her own space when she wants a break. Great quality and so worth it!

I love that the pieces were so easy to mount, the configuration could be easily changed. The panels separating each area slip in and out, giving Mum some time away and puppies safely contained. Easy to clean and store away when whelping is finished.

Wish I would have purchased the taller walls first but it worked awesome for my 11 golden doodle pups. The only thing I wish is that they made it one side smooth and the other side designed so you can put the flat side in so it just a spray and wipe kinda deal but overall I would buy this over and over. It’s perfect, well made and versatile.

Wish I would have bought when I got the original whelping box but wasn’t sure it would be needed. Ince puppies start growing and moving around it quickly becomes a must have! Mine use one side for eating/sleeping and the other side is totally for play. Gives everyone a little more needed space. A little expensive but it truly is worth the money.

This was the perfect addition to give the pups a little more room to stretch as they grew. Easy to assemble and move with help.

After the puppies started running and playing I put this addition so they can have more room. They love it
