I use the Earthborn great plains and it has bison in it. I really like it! I used Fromm since Lola was a puppy but went grain free and it didn't agree with her so my vet suggested Earthborn grain free and I love it! The gas is gone and she doesn't go poop like she used to. Both my girls like the taste of it as well and they eat it right away. I know several others on here use it also and I haven't heard any problems yet.
