MY dogs get very precise measured amounts of food and it will vary according to work loads and how they do with it.
For example during the winter we feed 4 level measured cups of food each day with multivitamin, Raw egg and a few other things. The dogs get weighed every 5-7 days and a desired weight is maintained. For Rebel it was 60-61lbs during the winter, about 5lbs over what he competes at. When he is weighed if I see him falling under then he get a half a cup of food more, if he is gaining half a cup less. Believe it or not 1/2 a cup can really change their weight as to what the metabolize.
Now that the season is under way we go back to 3 cups a day and excerise. Once we have reached our target weight,(TW=weight at which the dog is leanest/strongest WITHOUT losing muscle) then I feed accordingly to maintain that weight. Rebel is currently 57lbs and that is where I am going to hold him. I can dry him out the night before a show and bring him in on the scales at 55lbs, the bottom of his class where I want him.
Here recently I have really really been conditioning the dogs so as Im weighing them now every 3 days when I began to see the weight drop some due to the increase in work, I increased the food accordingly.
As far as kibble and raw yess we do more of that as the season gets under way. I like to get them high protein sources straight from meat 2 weeks before a show I increase their protein intake considerably, usually by using raw liver, very good for them! Also you can add B-12 and B-15 but if you dont know what your doing I wouldnt give it through injections.
