My dog did awesome on Orijen but you could tell he only ate it because there was nothing else. He NEVER at a bowl at once. It would take him all day and all night. So we searched and searched and searched and found this, and he FREAKING LOVES IT. He will eat each feeding (2 daily) at once (this takes him several minutes, but still). It took him until mid-way through this second big bag to start looking like he did on Orijen, and I'm not convinced yet he looks
quite as good yet, but we're giving it more time. Here's the link:
Grain Free Formula
He is on the Venison one.
