Long story short, vet told me to put him back on his normal dog food after the special food, but I just wasn't comfortable doing that while I feared the food was the problem. I started looking around online and found that Canidae had changed their formula and it has made a bunch of dogs very very ill. The change was about a year ago, so all I can assume is that I've just now gotten a bag with the new formula (it's not very popular around here and there are only a few stores in the state that sell it). Some dogs died from it. I certainly hope Albus is on the upswing. He's acting better, but hasn't had a poop since the new special food. If you feed Canidae keep an eye on your pets please. I'll be switching his food...I'm thinking California Natural, but I'd be open to suggestions from everyone.
I'll note too that the vet said he may have eaten deer poop that made him sick. I'm always out with him on a leash and I've never seen that happen, but as you all know, the are fast when they want to hide something. He had no little buggers in his stool sample though.
