At 9 weeks old it is a slim to none chance that he’s experiencing a food allergy or sensitivity. Grain allergies are also extremely uncommon dispite what people on the internet say.

Anon101 had the best suggestion of wiping his feet off when he comes in from outside. Constantly switching his food at only 9 weeks is liking to do more harm than good. Realistically his food shouldn’t have been switched until he had a chance to adjust to his new environment since the move can be stressful on them.
