Awww i know how much you will miss them Rache and worry.
Am sure they will be ok, but i would be the same as you.
I havent fed Orijen, but i did feed Acana from the same company, and even though the peices were bigger they ate it no probs.
That is good and grain free aswell
The Acana is for all life stages too, so even a pup can eat that.
But if you are happier with orijen puppy that's cool aswell.
It is just slightly higher in protein than the Acana from what i have heard.
Others that have fed the puppy one will hopefully come in anyhow. xxx
