I for years and years fed Pro Plan dry food to my dogs. Now that I have 4 who go through insane amounts of food, I have switched them all to Pedigree. That seems to work fine although one dog very recently has started throwing up here and there. He was on Pedigree for months before this started.....but I am considering switching him to something else that isn't so "pretty". I remember when dog chow used to be big ol brown chunks. Now it is dark and light pieces, red pieces, etc. Any dog foods left out there without coloring? Other than going to a high cost food, are there any other decent less expensive foods? I currently go through about 20lbs a week for the 4 dogs....And pay about $20 for 40lbs.
