That's because sadly there is no magic thing we can do. Even the most knowledgeable and experienced could possibly lose a bitch.
There are multiple things that could go wrong before, during and after birth. Learning what could go wrong at each stage, how to spot it and what to do is important. Personally I wouldn't totally trust the internet for that research, some of the crap u can find online isn't helpful. When I was considering breeding I got a few books the best by far was the book of the bitch.
Then as others have said mentors. Reading about doing something is one thing, actually doing it can be another. Having someone on hand to help or at the end of the phone for advice for all those stupid little worries or big worries is a massive help. My girls breeder and my friend were massive helps with my first litter despite all the research I had done.
So while lack of knowledge and experience can put a bitch at higher risk and good knowledge and experience can put her in better odds it's still not 100% guarantee all will be well.
Wish u all the best with your girl.
