The additives used to keep this food from expiring makes me worried it will impact the dog so I have stopped buying this for my dogs

I don’t trust that it comes in a tin with “real beef”. So what’s keeping it from going off? Preservatives etc. I avoid it for food for me and really avoid it for dogs

My little fur ball only eats the food bought in these small foil trays, so I buy them regularly. The fact they’re individual serves is good, no need to store open cans in your fridge
