My girl is a very picky eater, I have used Pro plan, solid gold, solid gold millenium, Wolf King and pup formula's, Iams, canned mixed with kibble, protein powders to keep her weight up when she gets all finicky. What a headache she can be as much as I love her. Many people told me don't switch her, she gets hungry, she will eat. Never happened. When I did that I ended up with Aidan bringing down a deer and bringing it home to , you guessed it Beauty! I almost croaked! He rarely touched the thing but she went at it like a wild woman! I was not at all pleased. Things like that can get them killed....The reason for the kennel outside! But late at night we let him out ot go potty, and I called and called after an hour here comes my big boy with blood up to his chest and grinning! At first I thought he was hurt but the look on his face said it all! Beauty was wiggling all over the place and after inspecting the yard we found his little gift! Good god! Anyway to make a long story short, I now have her on Nutro Natural Choice Ultra, and she LOVES IT! I use a can of wet with her kibble same brand and she eats like a horse, her appetite has never been so good, nor has she looked better and nursing 14 pups!
