Mother Dog Biting Newborn Puppies. This frequently occurs when puppies are between 5 and 7 weeks in age or so. 🐶 why is your dog biting her newborn puppies?

A dog who has just become a new mother will often intensely focus on her puppies. If a puppy attempts to nurse during this period, his mother might react by biting him, or by at least making a show of biting him. When mother dogs do this, they’re trying to teach their youngsters how to do things on their own, more independently.
