Have you had her tested for worms and coccidia?
Sounds like round and/or hookworms
Because if she has either of those, and if you didn't deworm her she does have worms, she will never gain weight even if she ate a bag a day.
Hook or round worms most likely cause.
If she has either get some pyrantel from the vet.
Pups will have it too if mother wasn't wormed as they need milk for six weeks. They get the meds through the milk.
Mother should have been on puppy feed in time of nursing as well.
It is with our judgments, as with our watches; no two go just alike, yet each believes his own.
