Preservatives in Dog Food

[TheBandit]

I was wondering if anyone knows anything about the preservatives in dog food, like which ones to look out for and which one are OK. On the dog food that I buy, it says that there are multiple Tocopherols with Vit. E in brackets beside it. Now I heard from a couple of different people that Purina wasn't a good brand because they used chemical preservatives that aren't very good for your dog, but the bag says the exact same Tocopherols preservative as the kind that I buy, so does any body know if what this is? ?
Does anybody have any suggestions as for what is a good food to feed your dog? I just got a new puppy and had to take him to the vet as he ate a toxic plant, anyway the vet gave me some Eukanuba food, which I thought was supposed to be one of the best, but it has Chicken By-product meal in it. If anyone has any suggestions that would be great! thanks alot!

scroll down to "Preservatives".

The problem is that manufacturers don't have to declare anything they don't add to the food, so if they buy for example chicken fat from a manufacturer that is already preserved with BHA, they do not have to declare it.
