There are a couple of kinds of interventions for whelping, which is the process of a dog giving birth to puppies. Most people whelp their dogs at home and don't need much veterinary assistance. If needed, veterinarians offer scheduled C-sections and emergency C-sections, as do most clinics offering canine reproductive services. There's also a telemedicine service called Whelp Wise, which is a uterine contraction monitoring service. You rent equipment and put a uterine contraction monitor on your dog twice daily. It assesses the quality of the uterine contractions, the length, and timing. If whelping assistance is needed, injections of calcium or oxytocin can be administered based on what they see on the uterine contraction monitoring. If things aren't going well, you can always decide to change from a whelping at home to a whelping with veterinary assistance, which generally means a C-section.
