the rice can be boiled up and given cold to your pups, but i suggest that if you pre cook the chicken, refridgerate it and never re heat the chicken as you can give your dog salmonella if your not careful. you can also try scrambled egg, which will help settle the stomach. i have a 7 week old rotty pup and have just tried her with scrambled egg and it went down a treat. iams might be a bit rich for your pup, you should try something with less protein in it, to help stop the diarrhoea! something i have tried is arden grange, its a bit more expensive but well worth the money, also denes dry puppy food has been successful.
