Like i have posted here before.. A better brand dog food with Less fillers is better for your pup... Why feed them a large amount of food that is mostly fillers and have them poop it all out.
Atleast if you are feeding them a good quality food they are actually getting something from their food. Their poops are smallers and they are healthier!!!!

And by products... ack....
