There are no plastic welds, hidden slots, fasteners, or corrugations that capture and retain contamination and are nearly impossible to clean and sanitize.

Puppy rails are self supporting so there are no legs or supports to trap and endanger puppies. MagnaBox whelping box can be used without the puppy rails however the puppy rails cannot be removed without disassembling the whelping box. Once assembled, the MagnaBox whelping box can be lifted as an assembly and moved for cleaning or relocation.
The MagnaBox whelping box has a 'no bottom' design which allows for your choice of whelping pads, heaters or alternate flooring.
Whelping pads made from veterinary bedding (fleece) are recommended for flooring (sold separately). The MagnaBox whelping box sits directly on the oversize pad holding it in place and discouraging digging and clumping. Excellent soft absorbent surface to comfort puppies while keeping them dry and providing outstanding grip for small paws.
The entrance door features unique 1/3 and 2/3 height sliding doors which allow you to adjust the height of the opening depending on the size of the puppies.
Optional heat lamp stand is available and mounts with the same hook and slot design. Heat lamp of your choice can be clamped or mounted to the stand.
Optional playpen/Extension is available and attaches to the front of the MagnaBox whelping box. The MagnaPens are similar in size to the MagnaBox and doubles the containment area.

These are our current lead times per brand:
Note that Covid-19 has created significant logistical issues for our manufacturers and lead times are longer than normal. Also, a large portion of our items are made to order - this helps manufacturers keep costs down, ensuring a better price for consumers, and also to customize each order. In some situations, rush orders may be available. Please contact us at cs@petprosupplyco.com or 1-855-PET-PRO1 to verify total fulfillment time for your order.
Note: if the lead time is too long for the product you wanted, take a look at our list of fast-shipping brands per product category on our Fast Shipping Page.
Transit time after shipment: please add 2-5 days for lighter and smaller items shipped via regular carrier (Fedex, UPS, USPS) and add 5-10 days for heavier items shipped via LTL freight truck. Transit time depends on distance from the point of origin. All of our items ship from inside the United States. Please note the times below are listed in business days.
Our policy for free shipping on orders over $499:
- Items from Lucky Kennels, TK Kennels and Little Cottage Co. do not qualify for free shipping (their items are much larger and heavier than typical orders); the shipping cost for items from these brands will be shown at check-out
- International orders (get in touch for a custom quote including shipping costs)
- Orders shipped outside the contiguous United States to Alaska, Hawaii or other territories (get in touch for a custom quote including shipping costs)
- Very large items or very large orders that must be shipped via Freight that are subject to price surges by freight companies; though these situations are rare, if this occurs we will notify you of any potential additional costs and give you the option to keep the order or receive a refund.
Order Confirmation
As soon as you place your order you will receive an order confirmation e-mail and we will immediately notify the appropriate supplier to begin processing your order.
Item Availability
While we almost always have the most up-to-date inventory information, there are rare occasions in which an item may be unavailable or on back-order. If the item is unavailable, we'll let you know and give you the option of receiving a refund or ordering a similar item. If the item is on back-order, we will contact you directly and provide you with an updated shipment date. From there you may either choose to cancel the order or continue with the updated shipment date. Certain made-to-order items may have a longer than normal lead time. If this is the case, the lead time will be specified on this Shipping tab.
If you would like to confirm the availability or potential lead time of an item prior to purchasing, please email us at cs@petprosupplyco.com or call us at 1-855-PET-PRO1.
Delivery Estimates
For standard orders and for items in stock, we normally ship within 1 to 3 business days (as per the table above) and you can expect to receive your goods in 3 to 10 business days total. Fulfillment times vary widely if your order must be customized, made to order, is for large or heavy items, or must be shipped by LTL freight truck (as opposed to standard carriers such as Fedex or UPS). Please consult the "Shipping" tab for each specific product, where we list current lead times. Please note also that Covid-19 has severely impacted global supply chains and several of our manufacturers are experiencing extended lead times. If you are not sure about shipping times for your product or require a rush order, please contact us at 1-855-PET-PRO1 or cs@petprosupplyco.com.
Shipping Confirmation
We ship from warehouses all across the country, depending on the item(s) ordered and your location. Depending on the physical size of your order, items will ship either by freight or a regular parcel carrier such as USPS, Fed Ex, or UPS.
LTL FREIGHT SHIPPING INFORMATION
LTL (less-than-truckload) Freight is used when shipments are 120 lb+ or for oversized equipment, which results in a truck with a large container delivering your order. Our freight carrier will contact you once your order makes it to the distribution center closest to the delivery address specified, and set up an appointment time for delivery.
Pet Pro Supply Co. Free LTL Freight Shipping - Curbside Delivery
Our standard Free Freight Shipping option for LTL deliveries is curbside, which is to a delivery to a Commercial Address and does not include a liftgate. If your order is to be shipped freight, you will have the option to specify whether the item will be delivered to a Residential, Limited Access, or Commercial address. If there is no option to select a shipping location, then this cost is already included in the price.
We strongly recommend adding the optional Liftgate for all deliveries to locations without a loading dock or forklift.
Freight Delivery Locations
This option specifies whether the delivery location is a Commercial, Residential, Residential Business, or a Limited Access address.
- Commercial - These addresses are those defined by our freight carriers and/or zoned by local municipalities as commercial sites. Typically these addresses are zoned as commercial real estate or are used exclusively for business. Most commercial sites have tractor-trailer access and a loading dock.
- Residential - If the address used a residence, select this option. This includes Apartment/Condo complexes and dormitories.
- Residential Business - Any business being operated from a home, apartment, or other dwelling where people live on the premises is considered to be a Residential Business.
- Limited Access - Locations where deliveries are restricted, limited, or very far from a distribution center. Examples include:
- Place of Worship
- Restricted Areas - Secure Research Facilities, Military Bases/Installations, Correctional Facilities, Government Buildings
- Farms, Ranches, and Rural Areas
- Recreational Areas - Camps, Parks, Fairs, Carnivals, etc.
- Individual Storage Units
- Sites - Convention Centers, Construction Sites, Mines
- Schools and Universities
- Commercial establishments not open to the walk-in public during normal business hours
- Farms, Ranches, and Rural Areas
- Recreational Areas - Camps, Parks, Fairs, Carnivals, etc.
- Individual Storage Units
- Sites - Convention Centers, Construction Sites, Mines
- Schools and Universities
- Commercial establishments not open to the walk-in public during normal business hours
Freight Liftgate
A liftgate is a hydraulic lift that is attached to the back of a truck that can lower freight to ground level. Freight carriers prevent their drivers from assisting with the unloading of heavy equipment other than using a liftgate to ground level.
We highly recommend any delivery address without a loading dock, select this option.
However, please know that for certain very long items, such as kennels over 6' in length, a Liftgate will not be able to bring the entire order down to ground level. Please have the necessary manpower available to receive your items with limited delay to the driver.
