Pedigree has got to be near the bottom of the list of foods to feed any dog. Lili, why do you try to scare folks away from owning filas? A ranch, a 7 foot iron fence and lots of money? I don't have a ranch, I have a corner lot in town. I don't have an iron fence, I have a 6 foot vinyl privacy, and I'm not a millionaire. Proper medical care for any breed is not cheap. Yes, Filas do have a special temperment and yes, I think mine is the best dog I've ever owned, but physiologically, they are not different from any other large breed. Chicken bones don't cause gas, which causes bloat. No, they're not good for the dog, but they don't cause bloat. Bloat can be caused by eating too fast, drinking too much water too soon after eating, vigorous activity after eating, and also stress is thought to contribute. One thing to consider is to have the gastropexy surgery done preemptively. I had my girl done when she was spayed. God forbid she should bloat, but if she does, it won't lead to torsion. Saves money, gives me some peace of mind and reduces the chances of her going under the knife again.
