I received a sample of Embark and Preference over the weekend. I decided to give it a try and was really excited. I opened the embark and did as the instructions directed. (it didn't smell too good to me early in the morning, but I wasnt the one eating it.) My boy wasnt beside himself with excitement but he ate it. He had stomach gurglies and gas all day. :( I really wanted to like this food. I might give it another try, but I am glad they were free samples and I didnt buy them. I think we will stick with our Wellness Core for now.
