12 x12 Incubator


Rated 5.00 out of 5 based on 9 customer ratings
(9 customer reviews)


The 12×12″ incubator is a wonderful size for small breed and toy breed breeders.  Rescue groups call it “the nightstand incubator.” Reproductive veterinarians use it for “that one puppy” that may need special care, such as a nebulizer that should be administered to it alone.  Small, transportable and powerful.  Don’t let the small size fool you.  The 12×12″ incubator uses the same controller, heater technology and sensor as our larger units.  It is professional grade and used by some of the top reproductive veterinarians in the country.

The 12×12 incubator features:

  • Utilizes a special construction infrared heater with encased insulation to reflect more infrared wavelengths to the puppies.
  • A proportional controller reduces electricity to the heater as the internal incubator air temperature approaches set point
  • A medical grade fast acting sensor
  • A removable stainless steel top that is both easy to clean and makes cleaning the inside of the incubator easier
  • A dense closed cell mat that absorbs radiant heat energy as stored heat energy delivery a comfortably warm surface for neonatal puppies without having electrical current near the puppies.  The mat is highly moisture resistant, and has give and grip proven to help in hip development.  The raised areas of the mat makes puppies more likely to sleep on their back and sides–reducing “flat chestedness” that can happen in come breeds
  • A glass enclosure the offers excellent visibility, is easy to disinfect, and is important to create the thermal gradient puppies need

Small and toy breed breeders will often keep the entire litter in the incubator during whelping.  Get the puppies warm and dry and feed between whelpings.

    Although we have two large Incubators we also have one small 12×12 Incubator. We use this incubator for weak puppies to keep them separate from their litter mates to keep a closer eye on them and make sure they are not piled up on. We also use the oxygen concentrator to make sure the weak puppies have excellent pure air.

    I truly cannot say enough positive things about my 12×12 incubator. I swear it and the O2 concentrator have helped me save some prety tough puppy cases the past two months, including 3 fading puppies, Cases that normally would not have survived. These are truly a life saver and I can’t wait until we can get a bigger one so we can save even more puppies. Thank you Ken and Team for this amazing invention!

    Amazing! I have the 12×12 and use it with every litter. My pups dry off in a constant temperature. The peace of mind that the pups are in a consistent environment is fabulous. The humidifier keeps things perfect for my pups. I recently kept a pup with bandages safe and warm while he healed. The incubator was amazing for his recovery. Thanks for engineering the best for my most precious pups

    This versatile small incubator is the perfect size for newborns to transfer into while delivering littermates. It dries them off and perks them up with a dose of oxygen and keeps them thermoregulate while mom is having more puppies. If there is a small runt it provides a safe haven to keep it in that prevents chilling and gives you additional time to tube or bottle feed to let him acquire the strength needed to nurse from mom in a few days. I recently had a singleton that was born extra large and stressed and this incubator perked him up in no time. Literally minutes. It saved his life. About five days later the thriving pup was stepped on by his mom and he was again struggling to breathe. I turned on the incubator and concentrater and it took about five hours but it again saved his life. He was thriving and nursing off of mom that night. This is a miracle must have product for newborns.

    I run a rescue group for small breed moms and orphaned babies. We have 6 Puppywarmers (two 12x 12 and three 18×18 and our starter 8×8) in our group. We also do a lot of special needs babies with clefts, hydro babies and many other birth defects. I am a strong believer because we had a Puppywarmer and Oxygen Concentrator we were able to save a litter of four premature tiny only one oz chi babies. They were so premature they had no hair looked like rats lol. Thanks to Puppywarmer they are all alive and well today! We have saved hundreds more that would have not made before we had Puppywarmers. The consistent oxygen makes a world of difference in these babies and their outcome. We have been doing this and special needs for years. But with Puppywarmers and the consistent oxygen, we are able to save babies we never could have before! Thank you Puppywarmer for your help save the babies.

    This was a life saver for our Biewer litter of 5, our girl Suri had some pretty tiny babies under 2oz, that were gaspers, and we thought we were going to lose them, We used this 12×12 incubator to keep them at the perfect temp, and the oxigen concentrator together. If it werent for Ken being on the other end of the phone assuring us, and this product we would not have beautiful healthy babies here today

    My 12×12 Puppy Warmer incubator and 02 concentrator keep my pups warm and dry in a consistant temperature that is safe and reliable. They are so reliable that I get a chance to get some quality sleep because I don’t have to worry about them failing. My oxygen concentrator keeps the pups pink and thriving. These 2 units give me the tools to help my pups get a better start in life.

    Thankfully have not yet had to use my set up but felt that it was well worth the investment if it would one day save even one puppy.

    • Ken (store manager)

      We will be here for you when it is time. Consider using the incubator for the first two feedings. Puppies feed stronger and getting them to the right internal temperature leads to better processing of colostrum–and a stronger immune system.

    If your a breeder, this is a must have!!! Ken’s customer service is without a doubt top notch! I recently saved a itty bitty pup that had to be tube fed around the clock for the first 4 weeks of her life! This equipment gave her a chance at life. Without I know she wouldn’t be here today! Thank you!

      Thank you so much, Jodi! We have our own itty bitty puppy. Elvis was born just two ounces, 1/4 the size of his litter mates. We tell breeders: “If you have a grandchild with expressive eyes, you need a strategy.” Many breeders make sure the small for gestational age puppies stay close–as they have bonded with these puppies like no other.
