It’s a very sad way to have to learn something, and I guess I believe it should be up to breeders to make sure that prospective puppy parents know about the possible health problems of their breed, but a lot of them don’t. They just want to make the sale.
There are plenty of dog foods that contain more normal or average amounts of fats, but when you start feeding for low carb protein and fat go up, unless you are very careful to get very lean meats. But as you said, you don’t really know if that was the problem, so it may be that no matter what you had done the results would be the same. It’s just so hard to know. You can’t second guess yourself.
