The breeder I got Lexie from fed this too. I switched her over RIGHT away and she is doing GREAT!! She used to poo a TON and it was very watery and nasty. Ever since I switched her, she has little poos and it is the regular consistancy of poo. I feed her Ennova Ivo (All Life Stages) so I don't have to worry about her and Beau eating each other's food. She has also gained weight (the vet says she is VERY healthy now) and her energy is UP!
Good luck!
