Hello Shelby's Mom, Matthew answered a similar question a while ago and below is his post

There is a chance of any mammal, humans included, dying from giving birth. In dogs, most that do die, will die from a heart problem, a whelping problem or a post whelping problem.
1) There are a couple of nasty genetic heart conditions in boxers. Cardiomyopathy is one, Aortic Stenosis is one. These are diseases that can be fatal in a boxer. Both can be screened for and this potential for death of a dam is one reason why breeders should vigourously test their dogs for signs of these diseases. It should be considered that some of this testing can be expensive and should be factored into breeding costs.
2) Whelping problems that can cause difficulty are inertia, both primary and secondary. Primary is when a bitch does not actually go into third stage labour (delivery) and the pups are virtually left in to rot if they are not removed by emergency C-Section. Secondary inertia will eventuate in difficult labours (the bitch gets tired) or in big litters. Both these inertias can lead to uterine haemorrhage and/or a later dose of pyometra (literally pus in the uterus) both of which can be fatal to a bitch in labour.
3) Post whelping problems can be the afore mentioned secondary inertia. "You *think* she's finished", in rare cases eclampsia (lack of calcium, "milk fever" in cows) and haemorrhage.
Most or all are avoidable but one has to know what one is looking for.
Next, I'd have to question whether "fun and wonderful experience (not to mention all those cute puppies for 8 weeks!" is a good enough motivation to have puppies.
One edict breeders are taught early is to only breed to improve the breed. That is, can you make a better boxer by breeding. There are hundreds of boxers in shelters the world over, many of which come from reputable breeders no doubt but many more that come from novice breeders who didn't know what they were on about.
I don't put Peg in this category as at least she is asking at an early enough time to way the pros and cons.
Peg, a litter costs a fortune if done right. And no doubt you want it done right or you wouldn't be asking.
Starting with a 5 month old bitch, you have some or all of the following costs
Purchase price of the bitch
Cost to feed the bitch to breeding age
Cost of vaccinations
Cost of health screening for genetic disease.
Cost of worming the bitch till breeding age
Miscellaneous costs that crop up. A case of kennel cough requiring treatment for example
Stud fee - high because you will want the best dog available
Cost of feeding a pregnant bitch
Health checks on pregnant bitch
Cost of equipment, heating lamps, whelping box, towels scales etc etc
Puppies born
Cost of feeding nursing bitch (often triple normal)
Cost of post whelping vet check and probable oxytocin needle
Cost of vet check on new puppies
Cost of weaning puppies
Cost of vaccinations for puppies
Cost of worming puppies
I don't think I need go on.
I have a litter of 7 day old puppies right now, as the board knows and the cost of this litter so far is well over $3000.00
And we have 7 weeks to go
So here's some food for thought

This site takes you through breeding from mating to whelping 'virtually' and you might find it useful as well
