Whelping Box Size, by Breed

Consider the following when selecting a size for your whelping box:

• The weight of the bitch
• The size of the bitch - for both weight and size, if you find that your bitch is on the larger end for what is expected of her breed, you may consider a whelping box one size larger for maximum comfort of both mom and puppies.
• Number of puppies in the litter - if you're expecting a large number of puppies, you may choose to get a box one size larger than what you would need with a small litter.
• Temperament of the bitch - if she's prone to jumping, you may consider getting a tall box in either the Fab or EZclassic style. If she's prone to chewing, you may look for longevity with the steel Fab box as opposed to the plastic EZclassic box.

Size Selection: Measure the rectangular space occupied by your bitch when she is lying down, fully stretched out. Add a few inches to each side for comfort. Remember to add an additional 4 inches on each side if you will be using rails.
