Have them check the pups body condition if they aren’t already. If she’s losing weight then they need to feed her more than what is suggested — it’s just a guideline. I have a 5 pound Pom and a 5 pound Chihuahua. The Chihuahua eats over twice as much food as the Pom or she starts to lose weight. The Pom starts to gain on any more.
If she’s not losing weight and still ravenous, I’d have her checked by a vet for any illnesses that can cause that as a symptom — diabetes, cushings etc. Certain meds can cause it too if she’s on any meds.
