What I got from your story is that as a one off you fed your dog some raw pork you picked up from the grocery store and it got sick. Unless there's more to the story that you're not telling us, you've not even ventured into feeding your dog a real raw diet. It takes research, planning and effort and it doesn't only consist of meat.
I also see people here and elsewhere talking about giving their dogs white rice and boiled chicken. That's what you give animals when they are sick, because it's bland and easy on the stomach, but it's completely devoid of nutrients.
Did you make any sudden changes from one food to Orijen without slowly introducing it into the dog's diet by mixing increasing amounts into the old food? A sudden change will upset their stomach. Were you feeding the pup the Orijen puppy variety or the large dog variety? They sell 2 varieties of puppy food and 4 varieties of adult/senior.
The same people that make Orijen make another brand called Acana, you might want to give that a try...
