I’m not familiar with that brand of dog food, but I looked on their website, and the listed fat content is 27%.

I’m not a medical expert, so I can’t give an opinion as to whether that fat content would have any effect on a healthy dog with no genetic predisposition toward liver issues, but it seems possible it might have an effect on a dog who has such a genetic predisposition. And, unfortunately, we often don’t know that a pup has a genetic predisposition toward an issue until it actually goes from predisposition to disease process.
