Yep, I've checked it out. I love that site.
My dogs were actually both being fed Orijen, but I had to switch Luna to a low fat food because she's had pancreatitis a few times and the GO! Senior had the lowest fat content at 10%. When Suzie gained weight, we just switched her over as well. Hopefully the duck formula works out, it seems to be helping so far... but I will wait a few more weeks.
