Bitch eating habits - Page 1

This goes on welping or just nornal, she will only eat well if Im in the room., She does only what she has too  if Im gone or not there ,she is 4 now but this has gone on since 8 weeks, she has been feed raw as well as dry, no difference.She is not food agressive with pups or sire and visitors , I have to leave her 6 days a month and when I come home both water and food are the same as when I leave..I m gone 2 days at a time and worry .She is not over weight, but is a woking dog, why is she doing this?  what advise might get her to a good place with welping pups .She is spoiled but this is a bit much and at her age she should behave better !
