Here's why:
* Possible causes: Vomiting in a nursing mother can be caused by many things, including infections, parasites, food poisoning, stress, or even a serious condition like mastitis (inflammation of the mammary glands).
* Risk to puppies: If your dog is unable to produce milk due to illness or dehydration, her puppies will be at risk of starvation.
* Urgent care needed: A veterinarian can diagnose the cause of your dog's vomiting, provide necessary treatment, and ensure the puppies' health.
Here's what you can do:
1. Contact your veterinarian immediately. Explain the situation clearly and ask for an appointment as soon as possible.
2. Keep your dog hydrated. Offer her fresh water frequently.
3. Monitor the puppies closely. Make sure they are nursing and gaining weight. If they are not gaining weight or seem lethargic, contact your veterinarian right away.
4. Keep the puppies warm. They need a consistent environment, and a cold room can make their situation worse.
