My two are on James Wellbeloved, one on the senior stuff and the other on the adult stuff, and I've had no problems with it at all. My border collie used to have problems with, well, can't think of any other way to put it..... runny poo . Haven't had a single problem since introducing James Wellbeloved about 3 months ago.

I'd recommend you gradually add it to the diet, though, phasing out the old food, rather than one sudden change, or her wee tummy might object and nobody wants that
