What would be a good liquid Vitamins for Pet's

Does anyone know what would be a good liquid vitamin to give to my little dog? She won't eat that much, never has but when I put a powder on her food she will not eat. I feed her range free beef and buffalo and organic chicken. I also feed her Wysong can and dry food. I want a liquid multi vitamin and mineral supplement I can give her. Anybody have any suggestions please let me know. They have these at the Vet's office but the first ingrediant is corn syrup. I don't know if liquid vitamin us humans take will be O.K. or not.

Thanks
Jerry
