A whelping box is in short, a box of sort that is used for the bitch to give birth to her puppies in and is the puppies home for the first stage of their life.
At around 7 weeks into pregnancy, we need to start thinking about the whelping box. Let’s have a look at an easy way to work out which size whelping box you’re going to need, remember you should be doing this at the 7 week point at the latest as ideally you should have the whelping box set 2 weeks prior to the due date.
The advice we give when selecting the correct size whelping box is to measure from the nose to the base of tail add several inches for the incorporation of puppy rails and free room and then go for the next size whelping box up from this measurement. (This is advice only and is ultimately down to the customer to select the correct size) The puppies will remain in the whelping box usually around 4 to 6 week, this is when they become more animated and therefore need more space to get around. It can sometimes vary depending on the breed of dog and how big the puppies are and also the number of puppies.
