Unfortunately, you really meed tp have her eating a good quality puppy food. This will help ensure she gets the nutrition she needs. There are things you should look for in a dog after she delivers. If your dog has intense abdominal pain, pale gums and tongue, sudden drop in temperature or collapse she needs to be seen as soon as possible as she may have uterine torsion.
If your dog has a Green, smelly discharge from her vulva, fever, loss of appetite and listlessness, it is possible she has a uterine infection due to bacteria or a retained placenta and needs to be seen immediately. It is likely she has metritis which is a uterine infection.
If your dog is experiences muscle weakness, muscle spasms, tremors or seizures, limb paralyses, she needs to be seen now as it is possible she has eclampsia. Calcium supplements, Tums, cottage cheese or goat’s milk may help, but it might not reverse the symptoms quickly enough.
Here is a site with more information on this.
Look for breast infections on a regular basis. If a breast becomes inflamed, red and hard to the touch, your dog will need to be seen by your vet.
Raw eggs are not good to feed dogs, you should cook them first if you are going to feed them to your dog. Cow's milk can cause diarrhea and should also not be given, but goat's milk is an excellent supplement for a new mother. Goat's milk is also very close to a dog's natural milk and can be used as a formula for puppies as well. You can try coaxing her to eat with boiled chicken and rice as well. However, the pups do need to nurse every 1-2 hours as new borns and if she isn't going to take care of them, you will need to do it or lose the litter. Here is an excellent site on orphan pups which also applies to abandoned pups.
If mom continues to not want to eat or take care of her pups or has additional symptoms such as I described earlier, you will want to have her seen by your vet. If finances are an issue, the following place might be of help.
I hope this information is helpful to you.
Hope this helps and congratulations on your puppies.
