It is unlikely that a dog can sleep through labor.
Labor is a physically demanding process for dogs, involving strong contractions and the pushing of puppies through the birth canal. These processes are painful and exhausting, making it difficult for a dog to sleep during this time.
While some dogs may experience periods of rest between contractions, they are unlikely to sleep deeply or for extended periods.
It's important to remember that every dog is different, and some may be more prone to sleepiness during labor than others. However, it's generally not safe to assume that a dog will sleep through the entire process.
