Here's why:
* It could be a serious condition: Vomiting white mucus in a pregnant dog could indicate a variety of problems, some of which could be life-threatening to both the mother and her puppies.
* Only a vet can diagnose and treat: A veterinarian can perform a physical exam, run tests, and determine the underlying cause of the vomiting. They will then be able to recommend the most appropriate treatment.
Please contact your veterinarian or an emergency animal hospital immediately. They will be able to provide the best care for your dog.
