Bayley has had some horrific breath. We had been feeding both B's the Wellness CORE and Braydi loves it (she would love anything you put in her dish...) and all was right with the world however; Bayley over the last month or so just picked at her food and it seemed to be tough for her to eat...and her breath just seemed to get worse and worse. So I saw Wellness Small Breed and switched her to that. And...she LOVES it, eagerly eats it and her breath is SO much better! We asked our vet about it and she said it is possible that there could have been a protein in there that didn't like her, or the fact that the CORE is all protein could have been a problem too. In any case, our sweet Bayley kisses are back and she seems so much happier with her breakfasts and dinners.
