My Dog Had Puppies And I Dont Think She Has Enough Milk How

  a responsible breeder would be weighing the pups twice a day, 12 hours apart and keeping track. each pup should gain a little each day.
What makes you think she doesn't have enough milk? For the first little while, it's not actually milk that the pups will get first, it's a thick substance that will transfer the mother immunities to the pups. Plus, milk doesn't actually look like milk, so if it's just because of the appearance, don't worry about it .

Are the puppies nursing? Or is she pushing them away? If the pups are having a hard time nursing, put one on the nipple, place his paws on either side, and use your fingers to pump back and forth on the breast. That will start the milk flow. The pups will eventually start to get the hang of it. You can call a vet, or a shelter, and get their advice.

There is little chance that there isn't enough milk if the mother is healthy. If there is a problem, the mother will soon push the pups away. Talk to a vet if things don't start working soon, but don't just start feeding the puppies. You'll need professional advice to find the cause of it.
Why is your dog having puppies? Do you realize how irresponsible that is anymore? Take ALL of them to the vet and leave them. Hopefully someone who knows what they are doing will come along and adopt them. Take them to the vet and let him/her check them!! That's part of the responsibility of letting a dog get pregnant ...
Well if the puppies don ' t feed about every half hour, it might be something wrong with the puppy (take to vet if this happens.) But if you put the puppies to her breasts, and they don't eat then there is probably something wrong.
you need to speak to the Vet ... chances are that she does have enough milk ... nature usually takes care of things like that.
what does your vet and/or mentor say?
