What kind of dry puppy food do you have? You have got to get her to eat. Her temperature sounds good. Do you have Nutri-cal on hand? You should be giving her some of that. If you don't have any then try to get some from the vet or Petsmart if you have one close to you. Also you can syringe feed her some Pedialyte. Chicken alone won't have all the nutrients she need. Pedigree canned dog foods are the only ones I ever recommend because they are soy free. Pedigree puppy and Pedigree Healthy Digestion are good choices for nursing moms. Good luck at the vets. Please keep us posted.
