and dogs can bloat after they have had the surgery they just can't twist
Right. Sorry Monab!!! I was thinking you meant it could twist again....duh....
Motosmom, the foods you named are some of the most low quality and cheapest around, and this means they are not very digestible. Not very good for any dog, and especially not for yours.
Your dog needs a high quality food that will be easily digested. It may seem more expensive, but you will feed much less of it, so the cost is really comparable.
