I have six dogs 1 terrier mix, 1 pug/chihuaha mix, 2 dachshounds & 2 poodles ranging in age from 2 years to 9 years. I have been feeding them Science Diet Lite to maintain some control over calories because I free feed during the day when I am at work - long hours away. I am averaging $50.00 a month and currently looking for a more economical brand or a way to eliminate the free feed option but still figure out who ate so no one misses out. Any suggestions? Thanks, RosemaryB
