I concur with the above.

You want to switch her to chicken and rice only to switch her again shortly after? It is very possible that it will set her off. And you just added yogurt, right? That is risky in itself, particulary because it's dairy and a large portion of dogs are lactose intolerant (may not be as bad with yogurt, but the potential is still there).

I do understand the problem with rx foods, but after all we have been through with Ellie's diet, if she was feeling really well on an rx diet, we (including her vet) would be extremely happy.

I wouldn't say Apple needs to stay on the I/D for life. That is really up to your vet, or better yet a veterinary nutritionist and remains to be seen. But I'd be very careful with changing to chicken and rice with no veterinary oversight and then switching to something else and adding these other things in.

Remember that if she is taken off the I/D and/or things are switched up and she reacts to it, chances are she will need to go back on it for months to years and possibly for a life time.

Have you thought about talking to a nutritionist?
