You mention a bulldog vet as to where you get your answers. And I'm not discrediting your comment about their being a breed different than others...yet you discredit them/bulldog knowledgeable vets in your previous post of them wanting to put the dog with stones on specific dog food for this problem...I'm puzzled, now I'm not saying the dog food would be the "best" but if it can prevent more stones then I do not look down my nose at my friend who feeds her dog this particular food to prevent more surgeries with her dog. For multiple surgeries can't be good either...and the food is known to prevent more stones. So I'm sorry I'm in favor of something that prevents dogs from having multiple surgeries...even if it's not the healthiest of foods. One must pick and chose what's important with their dogs health related issues I would think.
I'm not going to argue and if I came across harsh that was not my meaning...but I do plan on doing more research and speaking with other forums to see what they suggest is a healthy bulldog food. I prefer getting my answers from more than one source. No disrespect...but...that's how I operate.
