I was thinking of switching Riley to BB about a year or so ago....
After inquiring with a few personal friends, and neighbors, etc.
I found out a few of them had pups who had digestive issues with BB.
I then decided personally not to feed it.
But I also know of people, on here, whose pups do fine with it.
A friend of mine also sent me this: I just looked at it again and
there are posts as recent as yesterday.
