How long has he been eating it? Some will say just do a cold turkey switch (that’s what my fosters get), and some will say to do a transition period. It all depends on your dog’s gut health. Things that might help with transition tummy troubles: canned pure pumpkin puree, ground psyllium, probiotics, digestive enzymes.
Also, one suggestion is to go from Beneful to a quality grain-inclusive food before transitioning to a mod-high protein grain free food. I like only gluten free grain foods like Nature’s Logic. Solid Gold Sundancer is like that also. Not sure which manufacturer makes Sundancer though.
I will say that my fosters eat Nutrisource grain free Lamb, Nutrisource Heartland Select, sometimes Nutrisource small/med breed puppy (has rice), Brothers Complete Beef and Turkey, and Nutrisca Lamb. It’s all mixed up together in varying amounts and they get probiotics and psyllium.
Frankly, I wouldn’t go from Beneful to Orijen. But that’s me.
