Ditto dogaware! Also check out the series of articles Ms Straus published in Whole Dog Journal, very good stuff.
I use the NRC levels [these are 20 years old, current ones are published in Optimal Nutrition by Monica Segal]
http://books.nap.edu/openbook.php?is...034965&page=44 and
http://www.nutritiondata.com/ to be certain my dog is getting what she needs. I make up a recipe including anything I might use and put the value to .01 if not used this time. The nutrient search tool is handy to find that missing B6 or manganese.
More meat, some liver and some calcium for starters. Sassy gets 50% meat by weight daily and that is only because she is sick, otherwise she would get at least 75% meat. Feed what you have prepared and fiddle with the recipe a bit as you learn and it will work out fine. Dogs get over cooked rice and chicken when sick for weeks on end and are fine, nutrient reserves are a good thing! If you are concerned just use the good stuff as a kibble topper, replacing 25% of the kibble calories.
