all of this negativity is ridiculous. im positive half of the people complainig are jus on the bandwagon n want to agree with others complaints. this new formula is faaarrrr superior to the old and is now being made at diamond along with almost every other high quality dog foods an the market today.and for all that say any dog food is gluten free has no idea wat they are talking about all carbohydrates have naturally occuring glutens. canidae just doesnt add gluten like many other companies. and although there is diversified carbs now the overall meat content has been raised. to address the diarhea: of course dogs mite be having some issues. with a richer more meat based formula it is more digestible so it takes time to get used to that. think what happens if you suddenly started eating way more steak n meat protein you may have an upset tummy for a while! also for all those that say they switched foods n there problems were solved is because the majority probably switched to a cheaper more carbohydrate filled food which will firm stools up because of lack of meat protein!!! I just had to vent because there is sooooo many ignorant and uneducated comments about the recent canidae changes!!!maybe try it for yourself instead of listening to haters. it is an amazing food that all my dogs love. if they have lose stools feed them a little less n stick it out for a while till it firms up!
