Here's why:
* It's dangerous to try and induce labor yourself. You could risk harming both the mother and the puppies.
* Your veterinarian can assess the situation. They can determine if labor is truly overdue, rule out other potential problems, and advise on the best course of action.
* There could be underlying medical issues. An overdue pregnancy could be a sign of complications that require professional attention.
Please don't hesitate to call your veterinarian. They are the best resource for helping your dog in this situation.
