/renew regular dog food eating after sudden loss of owner

by Aileen

Our 5 yr. old, pampered girl, is a laid-back, calm, loving friend, She was my daughter's "lifetime" buddy, inseparable, My daughter was notified she developed an extremely, rare, incurable cancer and passed away within two months. When she didn't return, the dog stopped eating, totally for almost 8 days, but drank water a lot. She searched endlessly for her partner and whined, quietly while looking. After several days of non-eating, bribery was tried with snacks, which worked but no dog food would be touched. We have tried mixing dog food with light snack bits, doesn't work well, just a very little at a time. She is a little livelier, loving especially to one or two people. However still avoids plain dog food totally but still drinks and goes walking with a few people. How long should this avoidance of dog food continue without problems for her and what can I do to help get past this loss? She is a very, loving, laid-back girl who is so gentle. Love her much.
