VEVOR Whelping Box for Dogs, 28.3 x 28.3 x 18.1in Whelping Box for Puppies, Whelping Pen for Puppies, Dog Birthing Box with Rails and Washable Pee Pad, Whelping Box for Small Breed Dogs, White

I have another box that was twice this price. I like these a lot. They have smooth sides so they are easy to clean. I raise toy Aussies so this one is a little smaller than my other one and I like that. I don’t use the rails on the inside. It has worked great. The only frustration is that I lift them to change the bedding and place the edges under the sides so pups don’t get under the bedding. The sides slide out if I don’t lift them carefully. I think I would like them better if they had one solid piece for the sides rather than 3 separate panels. They are easy to clean and store. Also very easy to assemble.
