Gary- I would be cautious about changing your pups food so much at 11 weeks and when you also just got him home. It’s important to let him establish a level of comfort in his new home before you go ahead and make a food change. These behaviors could be his nerves from being in a different environment.
Keep him on whatever the breeder had him on at least for a few weeks and get him on a schedule of eating. Keep him on a schedule for going potty too. When you do decide to change foods switch him overly slowly so as not to upset his stomach and look for foods that have a similar GA as the Royal Canin.
I know you’re not happy about feeding RC, however for his sake I think it’s best for a little while longer.
