Settled tum!
I moved my collie cross onto Burns after Royal Canin and James Wellbeloved gave her diarrhea - her tum settled really quickly and I've kept her on it since - she enjoys it more than the Bonaforte she was on when I adopted her and always eats it without hesitation. She'll eat the Adult or Large Breed (and probably any other variety given the chance) - I give her the large breed to slow her down a bit as she bolts it down!
