My Penny ate her Orijen last night and her poop came out so firm

First time where she did not have any poop stuck to her hair. And she loved the kibbles too. This morning I found her near the Orijen Puppy bag sitting and waiting, which was so cute because my husband and I taught her to 'sit'. I'm still mixing her old food with the Orijen to transition her slowly but she leaves the old puppy dog behind
