I have not found one, unless you start feeding them crap. No offense. I feed mine the exact same thing. I pay $26.00 for a 40lb bag. But I am in Texas. SO a bit of a differance there. Is it upsetting your dogs or something or you just looking to save some money??
well IDK about the other formula's but I just put Penny on Canidae ALS formula. It is a grain free. For a 17.6lb bad it was $28.00 and some change. ANd for the 35lb. bag it was like $42.00 and some change. Expensive stuff. But it is helping with her seizures and her weight
