I can't say about the specific brands; I don't think we have them here.

I can say looking at the ingredients, I have been staying away from anything with "animal byproducts." It contains a lot of stuff you would cringe at. And that stuff has a higher risk of contamination.

Just my thoughts.

Oh, I'm wondering why you are buying the food at the vet to begin with? Do you not have pet food stores like we have? Or is one a prescription food? It didn't sound like it, though.
