If you are using our Pregnant Dog Calculator in advance of the due date for your dog, we have several product suggestions from Amazon we would recommend for helping the whelping process go smoothly. A great whelping box alternative would be the Iris Plastic 4-Panel Dog Pen (for smaller breed dogs of course). You can easily place an EZwhelp Washable Whelping Pad in the bottom of the area due to its size. If you get a larger pen, then make sure to size the whelping pad appropriately. The pad pictured below fits the IRIS 4-panel pen below closely. It also will keep the puppies contained in a smaller area. A Stethoscope is also a very nice addition to a breeders collection, along with an Electronic Baby Scale for monitoring puppy development (the Salter scale from Amazon is the one we’d recommend for its price and ability to accurately read even with movement. Also, the contoured edges will keep your puppies contained as they develop), Forceps, and a Pet-Temp Instant Ear Thermometer. This thermometer can take a dog’s temperature within one second! A dog breeder necessity!

Pregnant Dog Calculator: How to Use

Simply supply the calculator with the date your dog was first bred. The date range needs to be in ‘mm/dd/yyyy’ format in order for the calculator to work. Then select the calculate due date button and the pregnant dog calculator will calculate the range of dates when your puppies are due. The calculator uses a range of 59-63 days so it should be accurate in most cases. However, a veterinarian’s professional opinion is always recommended. The vet can also take an ultrasound throughout your dog’s pregnancy to help determine the number of puppies in the womb and also the health of the puppy fetuses.
