As many mothers will likely attest, having a child is hard on the body. Most shiba mothers-to-be will go into the whole process with a thick plush coat only to end up looking a little worse for wear when all is said and done. In the end though, how could anyone argue that it isn't worth it? *ahem* (when done responsibly by reputable kennel club registered breeders).
(Keep in mind I can say this with the absolute conviction of someone who will never have to worry about giving birth).
