Why not mix a little of the previous kibble with grains in with the grain free stuff? That works for my terrier. One third kibble with grains, two thirds grain free kibble.
Yes, some dogs will have more frequent elimination on grain free, that’s not necessarily a bad thing. My dog with allergies does best on Nutrisca grain free kibble, however she does have more frequent small bowel movements (3/4 as opposed to 1/2). She is doing very well otherwise. So, I don’t consider it an issue.
