The insulated raised base floor panels keeps heat in and helps control the box temperature. You will love the strength, durability and quality of this box. You won’t find a better made Whelping Box.

Well I have to say.... I'm totally impressed. This is so well constructed and to think I almost bought a different brand. Thank you so much for all the advise and guidance with what to get. I will recommend you to everyone and explain that the quality is very outstanding.–Jeff Little

To begin with, I really did not want to spend too much on a whelping box. I finally gave up, and ordered one of yours. I have to say, this is a SENSATIONAL box, and can't ever foresee needing another, unless I need TWO boxes at once. This is such a quality product, I just had to write and tell you how pleased I am.–Lynn Stuby - Nevar German Pinschers - Martinsville, IN

I have owned the Jonart Whelping Box for over 10 years. It is the best and ONLY box of it's kind. I would recommend it to every breeder who is looking to get the very best in quality, reliability and usefulness as well as ease of assembly and durability. After several litters and loaning it to friends, it still looks brand new. It is truly a great product!–Jill Farrington - Buckram Bearded Collies - Doylestown, PA

"We have the Jonart Whelping Box and we love it! We have just whelped a litter of Whippets and it has been a perfect addtion to our breeding program. We received it exactly on the day that you promised and we were amazed at how easy it was to assemble. It is incredibly easy to clean and sanitize. We plan on using this whelping box many times in the future. We are very pleased and gladly recommend it to anyone considering this product!"–Ken Felts and Paul Wellons - Eloine Whippets - Atlanta, GA

After having used several different whelping boxes from homemade to the "latest" and "greatest" on the market, I still wasn't satisfied with the quality and/or durability of each one. Homemade was okay, but bulky and not easy to clean no matter the finish put on it. Other manufactured whelping boxes were flimsy to say the least and after a few uses, it was clear they were not going to have a long life span at all. A friend of mine mentioned that she had purchased a new whelping box and it was incredible. Always anxious to find a better "mousetrap", I asked her for the information on it so I could "see it myself". After several years of using my Jonart Whelping Box, I cannot envision EVER whelping a litter without one! It still looks as good as new, it's easy to store when not in use, extremely easy to clean and so durable I know this one will last forever. It is truly an investment worth every penny for the last whelping box you will ever need to buy.–Susan Lybrand - www.brandmarkennels.com - Lucas, TX

I purchased the Jonart Whelping Box when it first came out several years ago. I still have and use that very same whelping box. I have been using my Jonart box for almost 11 years now, and I wouldn't whelp a litter without it. I have recommended it to countless other breeders and as far as I know, they have been as happy with the product as I have. In my opinion, it is simply the best whelping box available to breeders.–Penny Hanigan - Brigadoon Bearded Collies - Newtowne, PA

We love our Jonart Whelping Box! This is a very clean, safe and well-made whelping box. The craftmanship and the attention to detail are excellent! Not only is the box useful and very functional, it's a pleasure to present! It's easy to clean, and best of all, our precious girl, Sassy ---just loves it!–Tiffany Rury - English Labradors - Granada Hills, CA

I just love my Jonart whelping pen. I have used it for a few litters and it still is in the best condition. Easy to disinfect, clean and comfortable for pups and mom. When sending puppy photos it presents the litter at its best. People have commented on the "beautiful whelping box" and I remark, "Nothing but the Best for my babies–Diane R. Mallett - Sirrocco Boxers - Vacaville, CA

The Jonart Whelping Box is a great investment! It's worth the $$$$$....  After researching and looking at many whelping set-ups for our first litter of puppies, my husband decided that we would order the Jonart Whelping Box. He is in the construction industry and was familiar with the materials used to build the box. He was convinced this was the best whelping box on the market (regardless of price) and he was RIGHT! It's easy to clean, assemble and will be the only whelping box we will ever need to buy because of the well thought out design and sturdy construction. Here's a tip: order the liners for the bottom of the box....they will protect your floors.–Monique Childers - Palm Springs, CA

I wanted to finally thank you for your help in rushing the whelping box to us. It arrived in plenty of time for "Angel" to get used to it before her delivery. The puppies were whelped, raised, and have finally departed for their homes - all the time they were here this box was their home. I was able to use the door pieces as needed to keep them in the box - as they grew I would use the larger piece and then finally both pieces. It not only was a breeze to keep clean daily but I was truely amazed at how easy it was to clean and put away. When you say it is the only box you will need, you are exactly right. "Angel" is a Labrador Retriever and weighs probably 65 pounds - she wasn't always gentle through the entire whelping & raising process - but not a scratch can be seen on any of the pieces. Please feel free to use this on your website - it is a great product! Thanks again!–Susan Dean - Oakview Kennels - Gordonsville, VA
