I've been away for 6 months in Iraq, my dog was very spoiled with cooked meals while I was gone and now I can't get her to eat. Any suggestions?

Hello from sunny Pearl Harbor, Hawaii. I'm currently serving in the U.S. Navy and just returned home from Iraq. My female English Bulldog was board at a local breeder's house who I've known for years now. While I was away, she cooked for my bitch. Lesson learned, I did provide her with 3, 30 lbs bags of Evo dog food. The bully has been spoiled for 6 months by eating cooked meals and also put on 10 lbs. My dog has not eaten in 6 days. She goes to her kibble, sniffs and walks away. I think I'm more stubborn than she is. I even tried cooking some lean turkey and beef and tried mixing this in with her food and she won't eat it either. I tried mixing can food with her kibble and still nothing. This morning I did try feeding strictly can food and she did eat half a can. I was always under the impression that the dog has to eat solid food and not soley can food. Can you feed only can and would this be ok? Please advise on how to get this bitch to eat without cooking for her.
