Hello, the diarrhea should resolve within 3-5 days if this is just secondary to the milk. If there are older tha. 4 weeks of age, you can dry to wean them off mom and transition them onto puppy food. If the diarrhea is worsening or if the puppies become lethargic and not eating then you should seek immediate veterinary care. Hope this helps and best of luck
