I did a lot of research before deciding what I wanted to feed Eros, and finally ended up going with Orijen 6 fresh fish as his main kibble. The vet thought it would be too high protein, but they also don't think twice to recommend Science Diet ick! He also had never heard of Orijen before. I think the high protein diet actually works well for Eros because he only really likes to eat his food once a day and even then it's only 1/2 a cup. He's been on Orijen for a little over a year and loves it. He's very healthy and has not gained weight from it (he's 5 lbs). He may not be a working dog, but he does tend to wear himself out running around the house and trying to get us to play "tag" with him. So I think in his case at least it's working out very well, and I see no need to change his food. Sometimes I give him Innova- Evo red meat small bites to change things up a bit, and Merrick's Before Grain canned food. He likes all three, but Orijen is his favorite. Every dog is different, so I think the best thing to do is try it and observe the changes in your dog.
