The 4 Best Dog Whelping Boxes
1. Unipaws Whelping Box for Dogs – Best Overall
The Unipaws Whelping Box for Dogs is a beautifully designed box that will help dogs and puppies feel comfortable and safe. It’s made with durable medium density fiberboard and smooth surfaces that are easy to clean and maintain. The entrance can fit up to three removable door panels that are used to adjust the door height. The inner walls are lined with a pig rail to keep puppies safe and prevent them from getting squeezed by their mom.
It’s also quick and easy to put this whelping box together, and it only requires one Allen key to finish assembling. It comes with a removable metal arm that you can use to mount cameras or heat lamps. The entire whelping box is easy to disassemble, and it folds flat for easy storage.
This whelping box is most suitable for medium-sized dog breeds and can be a bit too cramped for larger dogs. However, it’s also designed to be connectable, so you can combine two whelping boxes to create a bigger space for your dog and her puppies.
- Adjustable door heights
- Lined with a pig rail
- Quick and easy assembly
- Folds flat for easy storage
- May be too small for larger breeds
2. Hudson Screwless Whelping Box – Best Value
This whelping box is a raised garden bed, but it can be an affordable option for a whelping. It is made from high-grade vinyl, guaranteed not to rot, crack, or warp for 20 years. This means it can withstand puppies chewing on the edges and other rough abuse.
The inside dimensions are 42.25 x 42.25 inches, with 11-inch-high walls. This size is ideal for larger breeds who can step over the walls easily. On the plus side, it will keep the puppies secure within the box because they won’t be able to escape. The Hudson is easy to wipe down when a pup makes a mess, and since there is no floor, it gives you the freedom to use a material you prefer.
Assembly is a breeze, and it is easy to move from one place to another. On the downside, there are no puppy rails, but they could be added fairly easily with a few extra supplies. Since it is not an official whelping box and doesn’t have all the features of a traditional one, it’s in 2nd place, but we think it’s the best whelping box for the money.
- Affordable
- Made of strong vinyl
- Large box
- High edges
- Ideal for large dogs
- No opening
- No puppy rails
3. Lakeside Plaza Whelping Box – Premium Choice
The Lakeside Whelping Box is an excellent option for those willing to spend more money. It is made of FDA-approved HDPE plastic that is strong and durable, so you know it will last several years. The surface is lightly textured but still easy to clean and disinfect. We like that this box is easy to assemble and has slip-fit connections, so no tools are required.
There is a removable door with an adjustable height to customize to the size of your dog and puppies. There are ledge chair rails to protect the puppies from being laid on by their mother, and the box isn’t difficult to move from room to room when using the handles on each side. Plus, with no bottom, the bed is lighter and gives you more options for the type of material to use as the floor.
The medium size measures 42 x 42 x 18 inches, which is plenty of room for a medium-sized dog to stretch out with her litter. This did not reach the first two spots on our list because it is a pricey box and may not be affordable for some.
- Easy to assemble
- Handles
- Removable door
- Durable
- Easy to clean
- Pricey
4. Shirley K’s Whelping Dog Box
This whelping box has a low, wide entrance that allows moms to get in and out easily whenever they have to stretch their legs. However, this also means that puppies will be able to get out pretty easily, especially as they begin to walk on their own. So, we’d recommend this whelping box for the early days, but it’s important to build a secure fence to ensure the puppies remain in a safely contained area.
- Durable and crack-resistant
- Won’t absorb odors
- Easy to clean
- Low entrance for easy entering and exiting
- Puppies can escape easily
Buyer’s Guide – Choosing the Best Whelping Boxes for Dogs
Otherwise known as a birthing box or nesting box, a whelping box is an essential item to have when your dog is expecting. You want to create a safe environment for your dog and her puppies. This is why finding a good box can be frustrating. There are many factors to consider when choosing a box, but our buyer’s guide provides resources and tips to help you find the right one.
Considerations When Buying a Whelping Box
Size
To determine the size of the box you need to purchase, you need to know the size of your dog and the average litter size for her breed. You want everyone to fit comfortably within the box, with enough room for the mother to stretch out and the puppies to move around. If it is too large, your dog may feel exposed, making her feel uncomfortable and less secure.
The height is also an essential factor. If it is too low, the puppies could escape and be exposed to harmful situations. While if it is too high, the mother may be unable to get in and out easily.
Materials
There are pros and cons to each type of material. Generally, a box made of plastic will be easy to clean, and there are different grades of plastic, with some being stronger than others. If it is too thin, it can be broken with enough pressure. Vinyl is durable and lightweight, though if it breaks, there can be jagged pieces. Both plastic and vinyl won’t absorb fluids, making them more sanitary and less likely to harbor germs and parasites.
You need a durable box unless you are going to use the box only once; in that case, you can purchase a disposable box. Disposable boxes aren’t as durable but may work well, especially for smaller dogs.
Design
The typical design of the whelping box is one with high sides and a “door” for the mother dog so she can get in and out more easily. There should be puppy rails along each side that prevent the mother from accidentally pinning a puppy against the wall and smothering it.
Some brands have handles to make it easier to move from place to place, and the box may or may not have a bottom. The advantage of this is that you can place materials of your preference, and it makes the box lighter and easier to move around.
Cost
You will notice that whelping boxes are not cheap, and some are more expensive than others due to the quality of the materials. If you are on a budget, try to find one that fits your standards and offers the features you require. If you will be using the box for the long term, it is important to purchase one durable enough to withstand the rough abuse from the puppies.
Comfort
Your mama dog will want a comfortable spot for her and her newborns. Line the box with plenty of newspapers for your dog to use as nesting material. You can add additional accessories to the whelping box to make it nice and cozy.
- Heat lamp: Have the light offset so the dogs can move away from the heat if they become too warm.
- Liners: These should be water-proof and provide protection for the bottom of the box.
- Whelping pad: Since these are fleece-covered, they will help keep the newborn puppies warm.
Conclusion
As you can see, the whelping box is more than a place for your dog to have her babies; it’s a home and should provide security and comfort. Providing the best box will ensure that your dog is happy, and it reduces your worry about keeping the puppies safe.
The Pet Nap is our top pick and is molded from strong, flexible plastic; it will last for many years. For a whelping box made of premium high-grade vinyl, the Hudson is easy to set up and large enough to accommodate your dog and her litter, which is why we chose it as the best whelping box for the money. For a premium whelping box, the Lakeside may be pricey, but it is made of HDPE plastic and can be assembled without tools.
We hope that our reviews list helps you on your journey to finding the most appropriate dog whelping box and one that meets your expectations. Keeping your dog healthy is vital, but once you have a female dog, it is a whole new experience.
